what ph will my biological filter perform best at?

[poswhatever]

my ph is always at 7 but i was wondering if just raising it a little would help it break down ammonia nitrite and nitrate better?

Stable Ph is better then trying to change it.

agree, bacteria can live in a wide range of pH, no problem. Just keep your parameters stable and your bacteria will do all the work for you. However I prefer my tanks to be mild acidic so that the ammonia in the water isn't toxic to the fish

pH

The optimum pH range for Nitrosomonas is between 7.8-8.0.​

The optimum pH range for Nitrobacter is between 7.3-7.5​

Nitrobacter will grow more slowly at the high pH levels typical of marine aquaria and preferred by African Rift Lake Cichlids. Initial high nitrite concentrations may exist. At pH levels below 7.0, Nitrosomonas will grow more slowly and increases in ammonia may become evident. Nitrosomonas growth is inhibited at a pH of 6.5. All nitrification is inhibited if the pH drops to 6.0 or less. Care must be taken to monitor ammonia if the pH begins to drop close to 6.5. At this pH almost all of the ammonia present in the water will be in the mildly toxic, ionized NH3+ state.​
