question about treating for ich

[shortbusldtang]

I have a 12 gallon nano and about 8 pounds of small rock in it. If i treat with copper will it hurt the natural bacteria on the rock? I have no corals ... purrple seuda chromis two molly miller blennys a slippery ---- wrasse three crabs and one turbo... 3 inch live sand bed. The purple one has ich badly. was wondering best way to treat. Thanks

Since all you have is LR, wouldn't you be able to hypo the entire tank?? I hear hypo is a better treatment and less harsh on the fish.

So hypo is harmful to lr ... Any other suggestions.?
