ok so I cleaned out my freshwater tank pretty good, took all the sand out washed it out pretty good, cleaned the sump out spotless, the hoses, pumps etc... and have refilled it and have been cycling just freshwater for now, but before I put in salt water im wondering about snails. since all the plants I had in there prior I have a million little snails in the sand that come out at night go on the glass then go back on the gravel during the day. should I some how try to sift and take them out? im just worried that when they die from the salt water, they will mess up the new salt water, or will it even matter?
