Hi all I've got a regulator which fits onto Clarke disposable bottles. I want to convert it to run FE's so I bought the D+D convertor from AE. It fits the FE fine, but has a different thread to the regulator. Does this mean that D+D have their own specific thread like Dennerle, or am I missing...

Hi all. I was wondering if anyone has come across this problem before - the co2 piping in my goldfish tank seems to break down. It's like it crazes and then releases the co2 from the cracks before it gets to the diffuser. That in itself isn't a problem because the bubbles it releases are quite...

Hi all I've been doing a bit of thinking (don't laugh - it's not funny :D), and I came the the conclusion that the solenoid I use on my welder will do the same job on my co2 system. So I tried it and it did. Welding solenoids seem to work out cheaper than solenoids designed specifically for...

Hi guys I've been using disposable bottles from Machine Mart, but I've now bought a FE so I'd like to convert my current unbranded reg to fit a FE. Will the D+D converter be suitable? It says, 'Converter for use on the D & D CO2 Set for fresh water and the JBL CO2 Set Easy system to allow the...

Ok, this is soooo strange. I've just rinsed out my 2 drop checkers. Filled them both back up again, with exactly the same solutions, one is blue and the other is a diamond green colour!!! So strange! Both solutions are exactly the same! I've retried it loads of times - the small drop checker is...

Hi all I don't think these have been shown before, so I thought I'd post them here because they look good! http://cgi.ebay.co.uk/Brand-New-CO2-Mix ... m153.l1262. I don't know what this would be like although it looks interesting (but big!) http://cgi.ebay.co.uk/CO2-Diffuse-React ... m153.l1262...

Hi all. I'm currently using 2 Hagen Nutrafin canisters in my low-tech tank, and I'm using the ladders that come with them, but they're so unslightly! Does anyone use glass diffusers with them, or is the pressure not great enough? Also, would the diffusion rate be as good as with the ladders. Thanks!

Hi all I was wondering if anyone could show me where I can buy a Co2 regulator for a disposable cylinder (like the welding ones). I've found that, as long as I buy them from Machine Mart on a VAT free day, they work out cheaper than buying a fire extinguisher and refilling it (since refils are...

Hi all I've just ordered new stuff for my drop checker because I was running out. I've ordered the 4dkh and the Refil for the JBL Permenant C02 test which is labelled bromothymol blue. I've added 3ml of 4dkh solution and 3 drops of bromothymol blue, but the solution turns a dark blue. I thought...

Hi all. Just thought I'd mention that Machine Mart do VAT free days every so often (you have to subscribe to them though, I know you can do it in-store, not sure about online), and they sell 600g Clarke Weld bottles of Co2 for £7.99. Normal price including VAT is £9.39.

Hi all. Does anybody know if you can use the larger Cal Aqua (17") with the Eheim external filters which have a 16" hose? Thanks

Hi all I need a regulator and solenoid for my FE - I saw this one on eBay http://cgi.ebay.co.uk/Dual-Gauged-CO2-R ... .m14.l1318. Anyone had any experience with this one or could recommend me a better one? Thanks

Hi all I was wondering if anyone here used the Dennerle re-fillable Co2 canisters (the classic line range)? I read somewhere that the bottles are only refillable by dennerle stockists? I can't see how that would be, but it does mean that I won't be able to go with a dennerle kit if it is the...
