I noticed when I had a bacterial bloom it glowed a funny color due to the light spectrum over the tank. I would like to suggest however that you install a bio pellet reactor and use microbacktor 7 with it. they accidentally told me 6 milliliters 2 * a week for my tank size and it was way too much. once I got it right though this stuff is great. the tank consistently reads 0 nitrates since doing so.
