Around day 35 of my cycle, I started having algae and the tiny white worms, forgot the name. 0 ammonia & nitrite and 20-40 nitrate with lights on for 10 hrs.
I did not have a fish in there, but had 1 golden mystery snail, 4 Amanos, 8 baby RCS free roaming in the 5g planted tank.
I decided to turn off the lights every other day, after i did 50%WC, removed all the stringy grey hair color algae, stopped adding adding liquid ferts, and fed the invertebrates every other day. The situation corrected itself in a week.
