So my tank is about 2 months, it might be coincidence that i'm getting a diatom outbreak right, but i was wondering if it's possible for an diatom/algae outbreak to happen after cleaning my equipment. I cleaned the HOB, heater, and powerhead (and replaced the filter floss).... all before a water change. I only have a 10 gallon and it just hit me that even if my tank was mature... would this spark an algae outbreak in a tank? or is it just new tank cycling woes?
