I know of no solvent available to the public that gives bubble free joints (and if they do it's at the cost of bond strength), They've always been found wanting, if you know of one that doesn't I'd very much like to hear about it. computer cutting is not the issue, making sure it's level FLAT...

that may sound expensive but it's not, reasons are: 1) the joins will have better quality, no bubbles 2) it is a fair amount of work cutting the pieces right since making sure they align almost perfectly so application of the acrylic cement gives the desired result 3) and I'm sure their acrylic...

another thing that's just occurred to me is that trickles filter, especially those with rotating spray bars and DLS, get the media UNIFORMLY wetted due to the gravity forcing effect. Channeling is virtually non existent, this make for an extremely efficient use of the biological media. With a...

you can have a totally silent sump setup if you know how to do it, that's my point. the biggest noise contributor to my fish only sump setup is the Eheim 2262 pump! Deltec HLP pumps are probably the quietest available, if they were on Eheims canisters you'll hear no noise. The only problem...

funny, I was about to mention rotting waste as well. And having it trapped in our filters is not a good thing. With a sump arrangement like Simon's he just takes the sponges out, gives them a scrub and rinse and puts them back in again. With a canister filter I have to disconnect, open the...

Clive, It was a long time since I read Thiel, but he stated that biological filtration takes a lot of oxygen, it's just that I don't have the laboratory equipment to find out how much. When you say the plants supporting the fish etc, it's not only the fish but also every other oxygen consumer...

That's not correct. It depends how you engineer them. Usually it's because people have bad overflow or syphon box design and they get gurgling etc. . . Noisy pumps don't help at all. :o Will drive everyone round the bend. :shock: If you use a trickle filter the sound is actually very...

considering the size of the tank, how thick is the acrylic and how many people did it take to move it? Pretty scary proposition, but a whole lot less scarier in acrylic obviously. I take it at 70cm that should just fit through the front door? :shock: I take it that it's braced? Also, who made...

Clive, from what I've been told it's 8 mg/l is the equilibrium level for water (of course this depends on temperature and altitude etc), but let's take that as our figure to work with. So no matter how much splashing around one does, this level cannot be increased since it's the equilibrium...

Re: 10 day old tank, stem plants sick - advice please. EI t Good God! I NEVER knew LED lights could be THAT strong. If you want to halve your light intensity double the distance from source to light (since light radiates inverse square), who knows you might have sufficient ceiling room, and...

use lava rock or alfagrog, just as good as SIPORAX and efisubstrat and nowhere near as expensive: http://www.ketteringkoi.com/acatalog/Filter_Media.html I quite like the ADA bio rio myself but could not get hold of it, it's basically lava rock, but in smaller pieces, so even Amano had the...

I don't get this thread. Why would anyone advise using SIPORAX in a CO2 reactor? That would literally be nuts!! A CO2 reactor is basically designed to do one and only one thing: put CO2 into the water. It is not meant to be, and should never be mistaken for, a biological filter (supplementary...

the question here is maintenance, the 2078 is easier to maintain, but it only has 8 litre filter capacity (with 0.6 litres for the prefilter) I won't be running my 2260 like most people, I will feed it via its own prefilter arrangement which means that the whole canister is NEVER touched at...

Re: 14 foot Planted Tank ................ is it possible ?? has anyone ever done any CO2 measurements in sump setups? let say, for the sake of argument, that water when gone through the sump and returned had all its CO2 taken out, this would undoubtedly mean that we have to use more CO2 to...

this is just a guess since I'm an amateur, and you'll have to excuse me since I'm not a chemist so I'll have to make educated guesses and assumptions, which I'll gladly have corrected: well a large water change will take out spores and drop the ammonia levels as stated, but is would also reset...
