cloudy water, bacteria bloom?

My tank has all of a sudden become cloudy. I am 99% sure it is due too a bacteria bloom. I have read that it makes pH drop rapidly, which is what I am currently experiencing. My tank is fairly new(3 months). Diatoms are gone, water is good, except pH. There is a bit of green algae on glass, but I believe it is from an accidental overdose of phytofeast. I am currently dripping a solution to maintain pH. The day after I stop dripping the pH will fall to around 7.5. Any way to get rid of this without dosing anything unnatural, unless its my last resort. Or is this a game of patience? Thanks.
