Lots out there here's another example https://oa-aquaria.co.uk/18x18x18-lhw-aquarium/

Ok, a bit more analysis. I've made some assumptions as follow 1 - Your tank height including stands is 1.5m 2 - The pump is running at 100% Your main tank is ~600 litres. Taking into account the head on the pump, you'll be getting 6000l/h The main open drain will flow ~18000l/h running fully...

@warriors Just for clarity could you confirm the function of each pipe in the weir photo, and also the role of the four pipe in the picture showing the right hand end of the sump. The idea with a Bean overflow is that all the control is done using the gate valve, which is on the primary drain...

@DrPhilG Can you provide more details of your sump setup, drains & weir configuration. People can then probably help out, probably best as a new thread.

Here's another variation on DOOA currently on KickStarter https://www.kickstarter.com/projects/terraplanter/terra-planter-the-inside-out-hydroponic-planter-pot

The key thing here is that you've actually tested it too many people don't. You might want to think about putting the return pump on a float switch, in the event that there's not enough water in the return section to prevent it getting burnt out.

Using the diagram from @Andrew Butler the pump chamber is 9l of water, you need to be able to hold this in the main tank in the event that the inlet blocks, which means that the water surface needs to be 2.1cm from the top of the tank to prevent water spilling out of the tank. That's assuming...

I'm currently talking to Sigma Aquatics in the West Midlands about a custom opti white tank. Might be worth getting a price from them https://sigma-aquatics.com/

Interesting, 500mm height will be down to the 12mm glass thickness, I'm guessing. Real shame I've only got room for a 1180mm long tank!

One of the main things to think about is the size of the 'overflow' which then comes down to all sorts of maths around hydraulics. The width of the opening into the filter section (lets call it a weir) along with it's height will dictate the maximum flow rate that can be achieved. Of course...

Not sure I'd like to use that as a stand, you're relying on the fixings holding the top horizontal member to take the weight and not sheer.

Personally I'd be looking at 2.5mm2 cable. Whilst in theory 10x300w is within the limit of a single 13A plug it's a bit close, blowing the fuse on a 13A plug will take 10 tanks heating off line. The other thing that you have to consider is what you're plugging the 13A plugs into ? If it's three...

Two sheets of 18mm ply, with some 34x34mm planned battens in between, gives you the required 70mm Battens:https://www.wickes.co.uk/Wickes-Redwood-PSE-Timber---34mm-x-34mm-x-2-4m/p/9000036468

If you read the assembly guide, the top shelf actually has the best construction for load transfer, I've included screenshots below. But effectively load is transmitted directly down into the legs, with no parts of the construction being exposed to shear forces. It should be noted however that...

Something to note here is that other tank manufacturers also adopt this approach Red See do it on their Reefer range of tanks.

Out of interest, how big is the tank ?

Take a look at the following YouTube channel. https://www.youtube.com/channel/UCEhx1ZATHf4YjV4dDNfpDEQ Although be warned, specification creep will take place after watching :)

Get in touch with the author of the YouTube video. Certainly knows his stuff.

Now if there was a 0-10v speed controllable heating pump that you could modify......

Ok, now you've got my interest, is the based on the price of a new pump, if so can you point me in the right direction

I'm not sure there's much cost saving in using a converted Grundfos pump over the Aqua Medic DC Runner range.

Ok this is interesting, looks like there isn't actually a flow sensor. From the Fluval FAQ "The system measures the water flow by reading the electrical parameters of the pump, and it has been calibrated by referring to a standard application, i.e. intake and output hoses of the same length...

I think the aquastop leaver is just being used a mechanism to enable the flow in a single action, later in the video it's clearly down.

I know it's been mentioned earlier in the thread, the following demonstrates building a stand out of scafolding parts. here's what it looks like with tank and stand covered. Should add this isn't my tank!

For those in the UK/Europe, currently £41 from Amazon for the Chihiros https://www.amazon.co.uk/dp/B07J4SR5SN/

Ah well, anything useful appears to have been removed by the OP

There's a review in Feb 2019 issue of Practical fishkeeping. Scores maximum marks across the board.

Ok. Think I've found the thread that you're talking about, really doesn't make good reading for ND to be honest. I've also just explicitly asked A4L on FB, here's their response. They also provided some pictures of their facilities, which they're currently expanding Lots of examples of...

Where are you getting the Aquariums4Life reviews from ? I'm not convinced that A4L and ND are related in anyway.

For those after more info, here's the detailed spec for the 100w unit https://www.ledgrouprobus.com//catalogue/product/sonic-100w-led-highbay-ip65-130lm-w-1-10v-dimmable

Sanj, where did you source all your rocks from ?

It's probably not just the filter itself, but the stand acting as an amplifier. Maybe try moving it round in the cabinet, or even adding a house brick/large stone next to it to damp the vibrationss

Mega flow.....

PFK had an article https://www.practicalfishkeeping.co.uk/features/articles/the-secret-to-setting-up-a-better-river-aquarium

Facebook page for them here, looks pretty good. https://www.facebook.com/Aquariums4life/ They're also pretty good at responding by email with custom requests / quotes. Not the cheapest out there, but certainly comparable to some of the better brands

New range from Evolution Aqua now available through Maidenhead Aquatics: https://www.fishkeeper.co.uk/eafreshwater Would like to see more detail about what you actually get but could be of interest.

Hi Folks, I'd be interested in what people think the minimum cabinet height would be to house a 5KG FE CO2 setup ? Thanks

You might want to take a look at the PLC thread here https://www.ukaps.org/forum/threads/how-to-use-a-plc-to-control-your-fish-tank.42993/ Of course every solution has it's pro's and con's , the key if you're using any form of automation is to understand the failure state

Quite like the idea of steel stand as well. Interesting that braceless tanks only get a one year warranty compared to three for braced. From what I can see on the pictures / videos silicon work is really good.

Certainly following this with interest, website http://www.aquariums4life.co.uk/ certainly has lots of info, and pictures looks good. Was considering an EAReef Pro 1200s, but A4L might offer a similar system for the same price, but with a few more customisations.

Be interested to see how this works out. I know Innovate marine do a similar 'sump in the rear' design http://www.innovative-marine.com/nuvo-aquarium/sr-80.html http://www.innovative-marine.com/nuvo-aquarium/sr-80.html

I agree, a sump is looking odd on favourite.I'm going to have the base of the aquarium drilled which means I've got multiple options in the future. Cost is a factor, but not a deciding one, but if you consider on a ~500L aquarium you're probably looking at 2 large canister filters, then a sump...

Thanks for the response, I've update the first post with tank size. I'm thinking about a sump, or possibly canister filters with direct plumbing in the back wall as I'd like to keep the rim of the aquarium as 'clean' as possible. Obviously with a sump come some down sides, mainly off gassing...

Looking for ideas on 'out of tank' heating, so either in filter, I believe Oase, and Ehiem have offerings, or in-line, hydor used to be the go to in-line heater, are there any others out there. **NEW INFO** In response to replies: I'm looking at a ~400L tank, 120x60x60cm internal dimensions.

As part of redecorating the lounge (more like rebuild) I've had the suspended wooden floor enforced, and I'm now able to have my 'dream' tank, 120x60x60cm. Which will sit in an alcove. Plan so far is to run this with a sump, the tank itself will be rimless and have an optiwhite front panel. The...

Ok, completely different place. The ebay one I listed ONLY does tanks, stands, and canopies, and is based in Leicester.

Oh, eBay feedback looks ok to me. Be interested in 'other' feedback.

@zozo - Thanks. Looks like getting them from the US is going to be cheaper. @hogan53 - Nope still not got that nice flat front face.

Nope not getting anything useful.

Thanks, It's the low profile front I'm after to get as flush to the aquarium glass as possible.

Hi Anyone know where I can get a bulkhead fitting like the one in the picture, ideally slip slip (no internal thread) in the UK. Several suppliers in the US.

Try here: https://www.ebay.co.uk/itm/Custom-Made-Aluminium-Fish-Tank-Hoods-Aquarium-Tops-Pelmets-build-to-order/202072210015 Not used them myself, but planning on getting my next tank from them.

Not sure if there's anything that can be done, but if images are used in a conversation, and then in a thread, then they don't appear visible in the thread. A good example can be seen here https://www.ukaps.org/forum/threads/how-to-use-a-plc-to-control-your-fish-tank.42993/page-3

Spot on the key here isn't accuracy, it's repeatability.

More good stuff. Looks like the image bug strikes again though :( Will raise it as a forum issue.

Citations needed for this one I think.

This might be worth a read :) https://www2.le.ac.uk/departments/npb/people/barber/files/sticklebackcare.pdf

The actual limit with the TC420 is 4A per channel, the amount of power therefore varies with the voltage of the supply to the TC420 and hence on to the LED's. Do you know what the output voltage of the power supply for the Chihiros A Plus light that you have is ? If so, divide 65 by the output...

I don't think the price is actually too unreasonable if the all of the listed features are included. More details on the product range here http://www.biopod.com/compare/

Just a heads up, wonder if anyone had seen these https://charterhouse-aquatics.com/shop/aquatics/aquarium-aquariums/biopod/biopod-grand I'm sure there's plenty of potential here would be interested in your thoughts.

Turns out the £10 is because it's an out of warranty repair ;) Seems I was far to honest with my initial email :(

All, I've got a couple of second hand TMC Aquaray 400 tiles, one of which has a whine when being dimmed. TMC will remove a component for £10. Does anyone know what they remove ? I'm sure if I knew what got removed I could do it myself saving £10 and the time to send and return. Cheers Stuart

I don't think cutting a 'notch' is going to be something that can be done in glass without specialist tools, drills, saws, jigs etc. But take a look at the following for an example tool

It's two pictures of one piece of wood :) It's within Efteling just outside the monorail.

Zeus thanks, really adds value.

Here's some of the missing bits.....

Spotted whilst holidaying in The Netherlands this week. It's a single piece about 6' tall, 6' long, and 3' wide. If only I had a tank big enough.

Defiantly missing from the "Zeus PLC Build" post above.

Thanks guys. Zeus, looks like some images are missing from you posts.

Ian / Zeus, How valuable is having the display on the PLC, I notice that there are units available without it. Cheers.

The question was quite simple, or so I thought. I'm not keen on the style of gauges provided currently with Co2 regs and wanted to gauge opinion on how easy it would be to replace / remove. So in summary, and after a little further research on-line it looks like replacement / removal won't be...

Just getting some opinions, I'm not thinking of running without gauges, just not with the gauges supplied.

Looking for recommendations of a a dual stage regulator to be used on a FE that I can easily (and ideally in warranty) remove the gauges from.

That's going to be a member of the Gunnera family. Just be aware one (Gunnera tinctoria) is listed on Schedule 9 of the Wildlife and Countryside Act in England and Wales therefore, it is also an offence to plant or otherwise cause to grow these species in the wild.

If you're looking to retain the connector take a look at http://www.maplin.co.uk/p/din-2-pin-line-socket-with-screw-terminals-fm43w You should be able to attach this to the output of an equivalent PSU

http://www.bbc.co.uk/news/uk-england-london-37600533 Not sure about the "polystyrene insulation under the floor appeared to swell" looks more like it simply floated ;)

Ok. Just asking the obvious question really. How about as you've previously suggested plywood for the main body of the tank. If you went with acrylic for the viewing aperture you could have a single piece bent to fit without any seams, joins or obstructions. Some pointers for a plywood aquarium:

Are the dimensions on the top drawing correct ? 60+30=90 so there's no space for the angled piece using the dimensions you've initially provided.

Wonder if anyone has given thought to a planted 'drop-off' tank. Like this one http://s774.photobucket.com/user/flofromaustria/media/Stufenbecken/20150606/DSC_2382_zpscfl1m5pn.jpg.html

I doubt that you'll see any compression of water in a typical industrial water plant. At 40MPa (equivalent of 40KM depth) you get 1.8% compression. For more details see: https://en.wikipedia.org/wiki/Properties_of_water#Compressibility

Brilliant pictures. As others have said flow could be interesting here, I can't help thinking that some sort of vertical spray bars could be the solution ?

I've been thinking about a new tank with the following dimensions 120x45x45cm. Having contacted a couple of tank builders prices are coming back at ~£270 plus shipping of £50-70. Over the weekend I go in touch with my local glass supplier, and they've quoted £150 for 10mm float glass cut...

Just got the following price from belio.pl for a 120x60x45 Optiwhite tank, shipped to the UK Tank - 370 Euro Shipping - 100 Euro Thoughts ?

Great scape, those rocks real give a sense of depth, it's only the spraybar that gives you a true sense of scale.

You might want to consider the following from Ikea, http://www.ikea.com/gb/en/catalog/products/80079363/ , see here for more detail http://www.ukaps.org/forum/threads/diy-ada-aquasky-style-led-luminaire.30044/#post-315220

Thanks for the detail. Taking the 48x24x24 tank and 3w LED's how many LED's would you be thinking about ?

I'm always interested by comments like the one above, how are you defining decent, and what's reasonable from a price perspective ?

OK. So your typical "wall wart". Still be interested in power loss.

What's an adapter style plug ?

Don't suppose anyone has run an aquabar through a plug in power meter ? Curious to see what the loss is in the PSU

Like it alot, what rocks are those ?
