I need to know a good way to detox a tank in a rush, in the last couple days i have noticed some of my snails belly up in the bottom of the tank, i proceeded to flip them over to help them out, and now i am seeing about 5-6 empty shells and a couple of my hermit crab shells belly up, so i took a chem test and as suspected the chemicals were to high. So i need to know a way to detox quickly. I used PRIME chemical, it says it detoxes/removes amonia, nitrate, nitrite from the water. PH was still fine 8.4 and the bottle of prime says to remove nitrite in a hurry add 5 times normal amount, so i did that. Should I do anything else to remove prevent further lose to my snails and potential lose to fish?
