Fish load...no idea. Lots of little fish, guppies, mollys, platys, oto's...constant fry. Too many. I gave away 15 platy's a few weeks back and need to do that again.
N03 - @40ppm before water change. WC - %50 weekly on Saturday with prime and excel.
Dosed thrive on Sunday...checked N03 on Tuesday and it was back between 30-40. I have reduced feeding to once a day and added a lot of plants.
