CB1 do you know how a lowered pH affects the denitrifying bacteria?


First of all it's not that big of a deal as you just add a little acid for every water change. Muriatic acid is cheap and a gallon lasts weeks in a system the size of Bruce's. We do this all the time in aquaponic set ups.

As far as lowered ph effecting nitrifying bacteria as long as the ph is dropped gradually the bacteria will adapt. In aquaponics 6.8 to 7.0 is a compromise as the plants like it even lower, but you don't want to go lower than 6.8 for the bacteria.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
