Hi
I had a Fluval Roma 90 which was running pressurized CO2 with a ceramic diffuser which I purchased from ebay, it use to be good, but for months now the bubbles are not as fine and some are quite large, I could deal with this in my 90 litre and still have a nice green in my drop checker.
However I upgraded to a Fluval Roma 200 and have only internal filters so I can't use a reactor and I don't plan to keep an external as I'm paranoid about the potential of a leak, so I have 2x fluval u4's, and I read if you let the filter suck up the CO2 it could harm the filter? so I normally put it below the outlet so when the bubbles rise they get thrown around the tank, however my fire extinguisher has already been going for about 5 months strong on my 90 litre and still has a good amount left...but a week in on my new tank and its dropping to fast for my liking since I've raised the bps, so I hope someone can give me some advice on how I can diffuse my CO2 better, I did some research and some people mention a atomic diffuser or Rhinox 5000.
I cant be sure how many bps I am at, I'm getting about 115 bubbles in a min, so its nearly 2bps, not sure if that's good or to less for a 200 litre, my 90 litres was probably 1bps either way I guess it don't matter as long as my drop checker turns green.
Hope someone can offer me some advice.
Also just to add my new tank has loads of tiny bubbles floating on the surface, I can only presume this is the CO2 that didn't dissolve, but it looks like someone has sprinkled loads of food in the tank. So is this normal? and if anyone can tell me which co2 tubing is best and where I can order some that would be great, as I'm just using plain air tubing, but I never minded if it was "leaking some co2" as it was lasting for ages on my old 90 litre, but I want to save as much co2 as possible now.
