I have 100lbs for sale if you are anywhere near London SE9? Used in my tank for 2 years. Incidently, I used 100lbs in a 180l tank. 3" depth is ideal for this substrate.

This stuff just keeps growing and growing. Its turned very thready - is this actually GDA as is no longer dusty?!? Obviously never seen it get this bad before. Its starting to form bridges between the glass and plants at the front of the tank.... Assume I just carry on for another week before...

Can't even see a fish now - absolutely covered in the stuff! Gonna be a long 3 weeks.... :(

Clowns mean no snails me thinks.... :twisted: I have recently installed a new light on the front panel of my vision 180 so xs light on the glass is a very likely issue. I've played with the reflector to try and keep the light off the glass - see how it goes. Gave plecs away as they did all...

Having an outbreak of GDA which I am struggling to get rid of. Scrape it all off and it just returns within 4 days... What's the best solution in people's experience? I hear differing advice from leave it for 3 weeks to run its cycle and then remove, to changing phosphate dosing / lighting...

Well looks like I'm going to take it all back....! When I moved to 5bps, I got home from work to the beautiful sight of all my fish gasping away - seems I over did it somewhat! That's the first time I have had such an effect with CO2, certainly something the Vario diffuser could never achieve...

Bravo, very tidy :mrgreen: A great DIY.

Dave, I'm seeing the same, or at least the air has dissolved fully by the time I get up in the morning. It's weird that I seem to be getting excellent dissolution, but the drop checker just isn't moving from blue. Running at about 5bps now, and solenoid is coming on 3hrs before the lights...

So far I've got about 2" of gas build up per day so that will mean daily venting. My bubble rate is higher than yours so will mybe reduce a little as I know you are easily achieving 30ppm from what you have previously said. Interesting that your gas build up suddenly stopped. Can't understand...

Well done Mr C - as always know what you are on about! :wink: Your test worked as you described. 2cm or so of CO2 was dissolved very quickly, then the gas line stabilised at the same level as before the extra CO2. As you said, the bubble does travel up the cylinder very quickly. The mesh...

Hi all, On James' recomendation, I upgraded my very average JBL vario diffuser for the Aquamas CO2 reactor hoping it would give me higher and more stable CO2 levels. Its not been running in the tank for 24 hrs and I am less than happy after spending £50 on it.... See pic for the set-up...

So is it a load of rubbish that you shouldn't use water directly from your homes' hot water system? Thought this could contain high levels of metals, so best to heat up cold water before addition to your tank?

Hi Eds, I've been using them for the best part of a year now on my Vision 180 alongside some T5 PC's. You need the brushings set as well so make the unit water tight. I certainly saw a difference when using them cf T8's. Not a massive difference, but did see more prolific pearling in...
