Hey Ron, Im using boiled peat moss water and mixing it at a ration of about 1:3 with aged tap water. Once in a blue moon when I get leuc eggs I have used this water setup with no problems. Im actually starting to cheat right now with the vents and have placed about 12 additional rearing sites for the adults within the tank. All of them are filled with tads atm so hopefully the parents will be doing a better job than I did. I dont know if you guys remembered but I mentioned I left one tad for the parents to raise and... well he made it SLS free... so im going to try a new method for rearing vent tads I guess... Ill get a pic up in a bit.
