Is it true that ph is higher in the evening when your lights have been on all day?.
I have no experience with the buffer additives so I really can't say how they are supposed to be used. Sorry.
I can tell you though it's more important to have a stable ph than an ideal one. If this is what your fish are used to and they are doing well then your probably ok. Constant ph fluxuations are hard on the fish.
The best way to buffer your water is through water changes as there are natural buffers in the salt mixes and it should keep your ph stable. Here is an article that may help. HTH
And yes, you ph will change depending on what time of day you test it.
