does co2 make fish lethargic?
In my 100 gallon, I inject pressurized co2 with a ph monitor. My ph out of the tap is 6.8 and by the end of the day, my co2 gets it down to 6.3. Today for example the ph reading got down to 6.2 which usually doesnt happen and everything was pearling like crazy, which is good. But my fish didnt even get excited to get feed this evening like they usually do. I think that they werent used to the amount of co2 that was in the water. FYI I have my co2 on a timer to where is turns off at night time and my o2 turns on fo about 6hrs at night.
My questions are:
I want to start increasing my co2 amount in my tank so the ph monitor gets to 6.2 or lower. Will my fish slowly adjust to the increased co2?
What should be my target goal of co2 in my tank?
100g tank:10 small angelfish, 1 harlequin rasbora, 2 albino cory, 2 clown loach, 1 rubberlip pleco, 1 bristlenose pleco and 1 apisto borellis.
Rena Filstar xp3, 2x32 and 1x96 watts with no co2.
