Excellent product
I was facing diatom issue for months, I try many things to reduce diatom, at last some one told me try microbacter7, my tank 120 gallon reef tank mixed. The result was not quick but after 2 week unbelievable tanks looks so clean sand bed, rock, water it’s a miracle, inside daily 20 ml. From last month I am dosing 20 ml every day.
