Looking fantastic. Drooling over your tank. Set mine up last week and already i'm swamped in algae, definately havn't got the knack for getting the balance right in larger tanks.
Ian, are you using a solenoid + regulator on this tank, or just a regulator? I'm getting REALLY inconsistent CO2 in my tank atm. I turn it on in the morning (yet to buy another timer) and it can be running at 1bps roughly, then just before i turn it off about 7pm it is running the same. Then the next morning i turn it on again and it may be about 1 bubble every 3 seconds. Infuriating.
Hi mate. Just a thought. I used to get water coming back up the CO2 tube towards my bubble counter. I consequently found that it took a while for the CO2 to push the water back before it started flowing at full rate. Are you having the same problem because if you are, you can rectify it by putting a check valve (non return valve) close to your diffuser. For a couple of quid it is worth a try. You can buy solenoids for about 20 quid and they are well worth having.
(sorry to butt in on your thread Ian)
