hello all,

I assembled yesterday a pressurized CO2 system on my 150L tank.
I've got 80W of light with 2x biolux tubes and 2x aquarelle tubes.
My pH is around 6,x, my gH is about 8, kH is around 3, nitrates 0 and
phosphate 0,5.
My question is what should be an advisable bubble flow for minute.
I set it up yesterday and I have by now a flow of 1 bubble every ~10 secs.

TIA

Paulo M.
