my tank always reads ph6 or below and i have 1.0 ammonia. my tank has been set up for a year now and my bass are a good 45 cm. My problem is that its always been like this and i have tonns of filtration and the bass a fine but i worryed that the low ph is not letting bacteria grow?? is this true?? also if i was to raise the ph how do i do it safely coz i know its not the bet to do??? my tanks 180 gallon and 3 monos. i do 2 watere changes a week of 50% and 1 fx5 and a massive diy wet/dry with 2 retern pumps pumping 1150 leters each per hour. what can i possibluy do to get rid of the amonia?
