i put some fungus stuff <Jungle tank buddies Fungus Clear>in my tank 4 days ago due to a fish that was acting like it had the flukes or had fin rot, i couldnt isolate the one fish cause he still was fast and hid in all the rock, i was afraid the other fish was going to catch it also so i treated the whole tank, my tank is a light green color,now for 4 days, i was going to redo my tank on monday, new substrate and rock, the question is do i want to keep this green water ?, i was going to save 50% of my old water when i first planed the redo the tank, now i dont want this green water, and i dont want to start with total new water either, what should i do
