Day 1 of dry ferts now 2 dead cories
Yesterday I started dosing dry ferts from GLA and when I came home from work today there were 2 dead panda cories in my tank and 1 Molly that looks like its on its way too. Did I overdose my tank? Are there certain fish that are sensitive to dry ferts? I have a 46 gallon medium but not heavily planted. I doses 3/8 tsp kno3 and 1/8 tsp h2hpo4 one day after a 50% wc where I also dose 4ml of flourish comp. Also doing flourish excel in this tank. I tested nitrates and it looks like they're in the 40-80ppm range using API teat kit. Any opinions, advice, and suggestions would be much appreciated, thanks in advance.
