Missed the "Wipe Out;" yes can use it if rinsed well afterward. You can fill with spring but will need to rinse many times if not using a strong 10X dechlorinator solution to detox any possible remaining bleach. Unless you have all those enclosures on hand; it's cheaper to go ahead and invest in the size that will hold the number of adults you plan to keep. Good info on Greys in here: http://Gray Tree Frog Care and Breeding . Good luck!
