Hi Andy. I've used the JBL Spiral in a few tanks and found them to be quite poor overall. In my experience they benefit from a good flow running past the diffuser to remove the CO2 enriched water, but even then the overall dissolution rate is quite low compared to others. I've recently switched...

Not sure what thread welding bottles take, and whether it's universal throughout? They'll fit fire extinguishers straight out the box though..If you can get around Mum's worries then that'll be your cheapest option :)

Going the Fire extinguisher route something like this: http://cgi.ebay.co.uk/CO2-Regulator-Ele ... 6557wt_941 Or this: http://cgi.ebay.co.uk/CO2-Regulator-Dua ... 3496wt_941 Would be your best bet - they're 'all in ones'. Then you just need some CO2 line, the FE, a drop checker and diffuser.

Yeah, 800psi is normal for a fully filled Fire extinguisher. ~40psi is fine for output also. Did you notice what high pressure read when low pressure was at 0? Have you tried switching the extinguisher off, removing and reconnecting the reg? Is the o-ring seal intact/seated properly in the...

Just hook everything up with a full cylinder and dunk in a bucket of water, will be pretty obvious if there are leaks. And to be honest, you'd be better leaving the pH controller in the box :)

The product is called "Carbo Plus" Been around for years, bit of info on it here: http://www.barrreport.com/co2-aquatic-p ... ystem.html For the purchase cost - ~£140, you can purchase a good CO2 kit. For the replacement block (which doesn't last more than a few months I've read) cost - ~£25...

Correctamundo. Don't buy that reg, it's useless and rubbish talking from experience!

The gauge with the larger scale, probably reading around 50-60 bar is the pressure inside your cylinder. Atmospheric pressure is 1 bar, so most cylinders are compressed 50-60 times that of atmospheric pressure when full. Obviously this falls as gas is expelled. The smaller scaled gauge, which on...

Yeah, have ordered one - looks like the best solution by far :) Also noticed this beast..! http://cgi.ebay.co.uk/6-way-Brass-Co2-s ... 1|294%3A50 :lol:

I quite liked the taste of my sugary, fizzy alcoholic concoctions after a couple of weeks on the windowsill! Only the slightly bewildered looks from people stopped me consuming much! :lol: I did wonder what sort of % alc. it got upto though :roll:

Cheers guys! That looks pretty neat LD, nice find! :D Bit more expensive, but for all the hassle it'll save it's probably worth it! Do you have one or not? Looks pretty solidly built so can't imagine it will be shoddy.

I'm just wondering what the easiest way to split one CO2 canister into multiple tanks(96L and 40L) is. Is it literally just a case of putting a Y-splitter on the airline from the reg, and then putting a needle valve inline from each piece of airline? Would I need special Y-splitters, or would...

Neither of their 'pressurized' systems come with a solenoid. For the money you'd be much better off with something like the D-D set. The disposable canisters are far too small for a 180L tank and the reg that would be compatible with larger, refillable canisters is really flimsy - I wouldn't...

I'd personally be terrified of using a flimsy reg like that on a FE. I've tried it before and the results weren't good. I'd agree with Simon - bite the bullet and get the proper stuff!

As you said, Excel isn't stable enough to be dosing once a week. That'd be like switching your pressurized CO2 on for one day a week! Seachem state that it has a half life of no more than 24 hours, so daily dosing is the best for good results :)

Shame, I threw a couple of these Hydor regulators away last month, really should have offered them up here!! :roll: The regulator in the latter of those 2 ebay links fits standard fire extinguishers.

+1. This actually works really well! I just use a limewood diffuser sitting below a koralia powerhead. Small bubbles get blasted around the whole tank, and it seems to be working great.

Don't buy the all-in-one shop kits if you're after saving money. They're very expensive compared to buying things separately online. You should be able to do it for £120 ish.

I'm using 2x2L DIY on a 100L tank and my CO2 is just about right, so I'd have though you would need more/bigger bottles for a 180L tank.

You've just said you've beaten the algae, and things are growing well, so why bother changing things? :)

Yeah, just needs a new o ring, same happens occasionally with regulators for diving. Definitely won't be cause for a new reg!

Bromo works as an indicator between pH 6 - 7.6. So I'd imagine any that measure between those 2 values will use it.

How cheap are these getting? I'm going to be tempted to go pressurized again soon! :lol: :evil:

Hey mate. I went down the welding regulator with everything else in-line, and to be honest it was a lot of trouble and hassle. If I were to set up again I'd definitely go for one of those 'all in one' type regulator setups, even if it does work out a bit more expensive.

Cheers Matt - made a bottle last night and it's bubbling away nicely. Just need to track down some tube to make my diffuser :)

Very small bump..:o

Right, I'm officially flummoxed! Can't really make head or tail of the Tom Barr reactor. Are there any other guides out there with step by step pictures? (And maybe big text with bright colours.. :lol: ) What's the function of the venturi loop thing? Is it basically a better version of...

Excellent, thanks for the link. I have a spare tube from a broken gravel cleaner and an old Juwel powerhead, so that could be perfect :D I know what you mean about the hassle. I just have no income right now so as much as I wish I could, I can't justify going pressurised :roll:

Hey all. I'm currently just dosing easycarbo, but have all the equipment still lying around for DIY CO2, so thought I may as well set it up again to run alongside the easycarbo. So two things 1) What have people found is the best recipe?I have some fancy champagne yeast which is supposed to keep...

Hey. I used to use one of the Hydor systems, though I forget which. One of them comes with an adapter for using other CO2 bottles, I take it you don't have that? I think I might still have my adapter stored away somewhere, I can have a look for it if you think it'd be any use..:)

Cheers Ed, I'll see how it goes :)

Ok, I'll try some bleach and see what happens. What ratio of bleach to water would be suitable? Well the bubble rate is steady without the diffuser on - if I just leave it coming out the CO2 tubing into the water it maintains that rate. But then again with the diffuser on I don't see where it...

Hi all. I've got my regulator etc sorted, but broke my Rhinox 2000 while trying to remove the co2 tubing (they seem very fragile!) So I thought I'd try out this diffuser, see how I get on: http://cgi.ebay.co.uk/Aquarium-3-Spiro- ... dZViewItem But no CO2 is coming out? :?: I think at first the...

4mm would have been pretty impossible. Lucky I found some slightly bigger kicking around. Just about managed to get that on after using the boiling water trick, cheers :)

It's going to need to stretch a fair amount..I'll give it a go and see what happens, cheers

Hey all..I ordered a regulator from Weld UK; http://www.welduk.com/Details.asp?ProductID=82 along with this nut to connect the co2 tubing; http://www.welduk.com/Details.asp?ProductID=291. However, the outlet from the nut seems to be around 6/8mm tubing diameter size, whereas I have, and all the...

Ok, I've ordered the regulator and part from the welding site, and the needle valve from ebay. Is this the right order of set up? Fire extinguisher----Regulator----Needle Valve----Solenoid----Non return valve----Diffuser Cheers Paul.

Thanks for the help James, appreciate it :) Would this be suitable? http://cgi.ebay.co.uk/Needle-valve-Fine ... .m63.l1177 I'm now wary of CO2 related things from ebay, hah! I also found this, wondered if anyone has any experience with it? http://cgi.ebay.co.uk/Wave-Twin-Nano-Me ... .m20.l1116...

Cheers Clive, makes perfect sense now! :D Seeing as I already have a solenoid, are there any dual stage regulators on their own that you'd recommend? Would, for example, this one be suitable? http://cgi.ebay.co.uk/NEW-SINGLE-CO2-RE ... otohosting I suppose if worst comes to worst I can sell...

I guess in retrospect I should've just bought a complete kit that was known to be good such as D&D - I've probably spent about the same so far! Anybody else got any advice on those regulators I linked to, or others that are more suitable? One thing I still don't understand is..if I buy a dual...

Quick look an ebay, would any of these be suitable or not? :roll: http://cgi.ebay.co.uk/mig-welding-regul ... otohosting http://cgi.ebay.co.uk/NEW-SINGLE-CO2-RE ... 0215409056 http://cgi.ebay.co.uk/Co2-Heavy-Duty-Re ... otohosting Cheers Paul.

Cheers Andy, makes sense :) What would the cheapest dual gauge regulator I could get? I don't really want to be spending a lot if I can help it.. Is it possible to attach a needle valve onto my current regulator in any way, or would I need a different one?

I am using proper CO2 line, but I guess at that pressure anything would give way. I've scrapped using the bubble counter because the water kept draining out. I'm just relying on my drop checker now. I'll run it 24/7 and see how I get on, whether oxygen concentration remains sufficient before...

Damn, that's a bit annoying! I guess it's what I get with opting for budget buys off ebay! :P Could I maintain surface agitation and run CO2 24/7, therefore cutting out the problem of the solenoid? Cheers Paul.

Cheers for the help James! Am I right in saying then, that if I had a dual gauge reg, but hooked it up in the same way as I am doing now, that the co2 line would still burst? Surely whatever pressure the regulator is set to the airline would eventually give way? Just a bit slower? It was only...

Hey Clive - the yellow knob is a needle valve as far as I know - it's turned to control the flow of CO2 out of the extinguisher.

I have the above solenoid, and this regulator: http://cgi.ebay.co.uk/Aquarium-Single-P ... 0220430124 I don't see any way the 2 could be connected together without the airline? I just put it together in what order seemed to make sense at the time :roll: :oops: The reg is attached to fire...

Hi all. I bought the £20 solenoid off ebay; http://cgi.ebay.co.uk/CO2-magnetic-valv ... 0209216803 Works fine switched on during the day, and is programmed to turn off at 8pm. Today was the first proper day it was set up, and at about 8:15pm there was an enormous bang and the CO2 air line had...

Yeah, I think I'll give the Rhinox 2000 a go, cheers :)

Hey all I'm new here! :) I have a 2KG FE setup in my Juwel 96, but I'm looking for a decent diffuser, but one that doesn't cost the earth..(cheapo :D ) I've seen a few on ebay, like these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... :IT&ih=011 http://cgi.ebay.co.uk/Co2-Diffuser-9000 ...
