awd79 Posted July 30, 2022 Share Posted July 30, 2022 Hi everyone- Was running a quarantine on some new fish. 20G cycled tank and running for months, no plants I added about half a capful. Kinda guessing the 2 teaspoon measurement. Anyway, tank is very blue. I am not sure if I added too much and what I should do. I also added Erythromycin and General Cure. Only filtration is sponge and HOB with sponge, no chemical. I read after the fact not to mix with Erythromycin but no where does it say what happens. I also they read after on the bottle it can cause an ammonia spike. Should I do a water change to dilute? Link to comment Share on other sites More sharing options...
