I accidentally added too much fertilizer(API Plant Food, liquid). Will it harm my java ferns? I have 4, 2 babies that sprouted from the leaves, one that has no leaves, but its rhinozome, and one that has two leaves. It turned the tank water a light yellow. It is a medium kritter keeper(a 3.2 gallon). And i plan to add a few anacharis or elodea, amazon swords, a moss ball, and a diy sponge filter. So, will it harm my fish or plants, can the yellow go away(i changed 50 percent of the water.
