    diffuser problem

    Its probably from the sugar yeast mix, use a check valve between the mix and the diffuser and that may help stop the flow of yeast to the diffuser, or maybe the mix is overdone.

    Absolute diffuser nightmare

    I never got more than 2 weeks out of glass diffusers without a clean before they dropped in performance. So Victor is probably right IMO, a weekly clean is probably best for peak performance especially if you only give them a 5-10 minute clean as I used to anyhow .

    Inline diffusers??

    Is the 8 the inner diameter of the tube?? I think it might be, not entirely sure though.

    Inline diffusers??

    I reckon you could get away using less flow when you use these because these things are so effective, the mist produced by the diffuser is so fine that it easily gets blown around the tank, the bubbles produced from my boyu diffusers usually head straight for the surface once out of the range of...

    Inline diffusers??

    I am a recent convert to UP diffusers but have used many many boyu diffusers over the last couple of years with good success I should add. IMHO the UP diffuser is far superior to the boyu diffuser, the UP diffuser is a different class altogether, way way better, if you think the boyu diffuser is...

    c02 Reactors

    I have made several DIY reactors that are made from parts easily available from B&Q. For about £25-£30 you can get enough tubing and the other bits and pieces to make several reactors. All the reactors I make work on the principal of gravity, none of them contain any media or bio balls etc...

    CO2 atomizer and DIY reactor

    Similar question to the above really, has anyone got one of the large size diffusers on a Tetratec Ex1200, is it a tight fit? does it fit at all? would hate to shell out £20 and find it doesnt fit snugly. Pity the boyu ones dont come in larger sizes they are a quarter of the price for exactly...

    Azoo CO2 Regulator Review

    Nice find, even better value when paying in Euro's :D be interesting to see how the needle valve behaves over time.

    Adding CO2 to a Tank with a pH of 6

    Are you sure the pH kit is ok, is it in date and what make is it, its not those strips by any chance? I would say its possibly wrong, I could be wrong as well mind you, Im no expert. But I would expect your GH/KH to be practically zero for the pH to be reading 6. Your GH is 2.24 degree dH and...

    Mazzei venturi

    Thanks mate I will see how I get on, I found a mazzei but he's looking for $50 and $20 postage, I will have a look around and see if I can get one a bit cheaper, the orange one you have linked is usually advertised as an ozone venturi for saunas, so not sure if its the same thing, I will try and...

    Mazzei venturi

    Hi Charlieh, thanks for that, any idea where you bought the mazzei, any links? the 384 mazzei comes in 2 sizes 1/2 and 3/4 inch any idea which one you are using, also what size tubing is on the filter that you have? The reduced flow rate sounds about the same as if you put a DIY external...

    Needlewheel CO2 diffusion

    Happy enough with that method alright but thats on a tank under 100l, this idea is really for a bigger tank circa 200l, atm Im useing a DIY pipe reactor on that tank and its reducing the flow of the filter. The maxijet is just an ordinary powerhead isn't it? I would prefer a dedicated...

    Needlewheel CO2 diffusion

    Hi Steve, Not totally sure tbh, I presumed the pump was plumbed inline after your filter, I dont think you could get CO2 mist into your tank if it went through your filter after going through the pump. I would need to check though how its plumbed in but I believe its pretty straightforeward. I...

    Needlewheel CO2 diffusion

    Just wondering if anyone has tried Needlewheel CO2 diffusion and what equipment/pump did you use? how successful was it etc. Not sure if anyone here has tried this method yet but it looks very interesting and should work very well, a good alternative to an inline reactor (which slows down my...

    Ladder or diffuser

    Ladder or diffuser

    If it works it works! The ladders do work well, ugly as s*&$ though. Personally I would say its a toss up between the efficiency of a ladder and a glass diffuser, not much between them other than aesthetics especially if using it on a smaller tank. I used two DIY yeast setups with two ladders...

    Ebay Regulators

    I have 2 of the last regulator you have pictured, I probably have both of them running for about 2 years or longer, no problems to report. If you have a ready source of CO2 you can easily do without a solenoid IMHO.

    Mazzei venturi

    Thanks Clive, yes I have come across that link already, they are very expensive, they are looking for £50 for one venturi without postage costs inc. I cant work out the postage until I fill in my credit card details etc , probably another £10 or so. Anyway they are too dear. This is the best...

    Mazzei venturi

    I know what you mean about the cost alright, any mazzei injectors I have tracked down from Europe or the UK have been very expensive, I will keep on looking though, they seem to be overpriced pieces of plastic fullstop, mainly because they are patented I presume. I will probably buy them from...

    Mazzei venturi

    Thanks Clive sounds good, any idea when the article will be published? I believe some people have run them off ordinary cannister filters with a certain amount of success, although obviously this is not ideal as it will restrict the flow considerably of the filter and the pressure required may...

    Mazzei venturi

    Does anybody know a company in Europe that supplies mazzei venturis suitable for aquarium use. Has anyone on the forum considered using these/is using these for CO2 diffusion?

    Hydor Ario

    ok Garuf didn't spot that, I seen mention of them on APC thats where I nicked the idea. I would say it would definitely work alright if you placed it directly under your spraybar or lilypipe to blow the bubbles around the tank. Johnny maybe one of the UK based guys will take you up on that...

    Advice on a ph controller

    Sounds like your needle valve is duff :? or your having extremes of temperature in the room.

    Hydor Ario

    These look very interesting, stick a CO2 tube on there and you have a diffuser that you never have to bleach, and that can't be a bad thing. www.aquatics-direct.co.uk/rangeViewer.asp?categoryID=102 www.marinedepot.com/ps_ViewItem~idProduct~HD01601.html They are basically a turbo airpump that...

    Inline Co2 diffuser

    These look very interesting, I just need to find out where to get them and I will try them.

    CO2 kits

    Personally I would like dials, good needle valve, brass non return valve, solenoid could be made optional? but would have to be decent quality so it does not run too hot for enclosed spaces, the cheaper ones run hot. I looked at WeldUK before but couldn't work out what to buy when doing...
