Just wanted to be sure that the generic version of Nolvasan is fine to use to clean the tanks for our corns? Do I need to let it sit? Or Rinse? A local lady gave me quite a bit of the generic but I'm wondering if I need to go ahead and purchase the Nolvasan instead since I can get it relatively cheap ($14.99 locally)? Also how long does the mixture stay good once you've mixed the recommended amount with water?
Thanks So Much
