I got my new plants about 4 days ago, ive had them in qt tank without light and filter, just water to see if there was any snails or anything...I did have a snail but it appeared dead in the delivery bag...I havent seen any other snails but I would like to get these plants in the tanks so they can get some light...i dont think these plants were ever in a fish tank with fish, i ordered them from a nursery so im not too worried about my fish getting anything but i would like to disinfect them before placing them in the tank...is 4 or 5 days enough time for qt and should i just use salt to disinfect them...if so how?
