Hello, I have a 36 gallon tank which I purchased about 4 months ago. I recently spent about $100 on fish. They all died of ich. I also have 5 snails. I was given copper treatment by local fish store only to find out it will kill the snails. So my question is can I reintroduce the snails at any point after treatment? There are currently no fish in the tank. I also read that you should never treat your main tank? I'm so confused! Any help will be greatly appreciated!!!!
Thanks
Thanks
