Hi..

Here is my new dosing plan for my 15 gallon wide tank (2.7wpg, 35-42ppm
CO2, fish load: 8 harlequin rasboras, 3 saes, 3 otos, 3 clowns, 2 corys):

35-42 ppm CO2 = 35-42 mg/l is to much.

15-20 ppm CO2 were o.K.

What does anyone think?

I think fish is the decisive factor.

30 ppm seems to be the norm these days, many people run much higher without
any ill effects. I keep mine around 35 ppm, which seems OK. I get too much
growth for my liking actually.

I thought his PO4 and K were rather high though. Not to mention too many
large fish for a 15 gallon.
