I’m adding 2.5 ml of Kent Freshwater Plant Supplement a week to the 15 gallon tank and turning the light on from 7am to 8am and 1 pm to 8 pm for a total of 8 hours a day to control the algae in the tank. It’s not bad right now with some film, beard and spiral algae, but I don’t want it to get out of control. I’ll also lightly feed only every other day.
In the future, once the algae’s under control, I’ll increase the photoperiod by 1 hour a day and increase the supplement by .5 ml a week.
