    Fixing a leaking seal

    They knocked money off for me as I've become a regular customer in recent months. The regulator retails at £79 and the solenoid at about £60 I think. I got them for less than that. The beauty of this is that the two are separate so you could buy the regulator first and add the solenoid when...

    Fixing a leaking seal

    After discovering a few other problems on my dodgy ebay system I decided to give up and bought an Aqua Medic unit from TGM yesterday. I got a great price for it and fitted it in seconds - no problems, great, simple little unit. My dad always says "Buy cheap, pay twice"!!!!

    Fixing a leaking seal

    It is threaded. The weld comment was supposed to be a joke. I thought CO2 penetrated all kinds of PTFE tape?

    Fixing a leaking seal

    Hi everyone, I have a bit of a problem that I need help with. A few days ago, literally a few hours before going to France on a school trip, my CO2 went off. After checking I realised that the bottle, which should have lasted for months, was empty after only two weeks. I had no choice but to...

    Tweaking CO2 levels

    I have recently changed my pressurised CO2 system and am having some difficulty in adjusting the bubble rate. I currently have the main valve on the CO2 bottle just over half open and am using the fine adjuster attached to the solenoid to control the amount but it is VERY sensitive and I seem to...

    D-D CO2 unit and microbubbles

    Sorry beeky, I've not been online for a while, I wasn't being rude by ignoring your question. I live on the Wirral but I've ended up sorting this out myself. After looking around in lots of places I settled on the 3kg bottle from TGM in Wrexham. Although it's slightly more per kg than some ebay...

    D-D CO2 unit and microbubbles

    Well I bit the bullet and ordered/blagged loads of stuff last night from various places. Thanks again for all your advice. I do appreciate it and hope to be able to do my bit in return for other idiots once I've gained a bit more knowledge. Just one more thing. You said the hard part is finding...

    D-D CO2 unit and microbubbles

    I like that suggestion because it's cheap! Trouble is my tank is 4 times the size of yours so to keep CO2 at a decent level would mean changing the bottle every 3 weeks at the most. Besides I want a system for my nano so I'm going to put the D-D one on that and go for the fire extinguisher type...

    D-D CO2 unit and microbubbles

    I'm almost sorry I asked now! But you are right, I've spent this much it's all or nothing now. I can't move the current unit any lower as the tubing is already pretty much stretched and if I'm going to buy more tubing I might as well change to a more appropriate unit. So, if I buy the one from...

    D-D CO2 unit and microbubbles

    Sam, thanks for the suggestion I'll have a look at that kit. ceg, thank you so much for the time you put into your reply. I'll try to put up a picture later on but for now I'll answer your questions: That is the right D-D unit you found but as I said it came with a power head. My tank is 65cm...

    D-D CO2 unit and microbubbles

    Thanks Sam, I'm running at 2bps at the moment that's why I'm surprised it's not having much of an effect, especially as I'm running on 100% RO (with added minerals to acheive GH of 5-6 and KH of 4-5). I wondered why the optimat was so cheap. If an offer looks too good to be true etc. Can you (or...

    D-D CO2 unit and microbubbles

    Hi everyone, I've recently (and reluctantly) gone a bit more high tech and added a CO2 unit to match my high-ish light output. I bought the D-D unit online and should have received a simple bubble counter/diffuser in one to sit inside the tank (that's what is shown on the website I bought it...
