have you either feshwater dipped or tropic marin dipped the zoos yet? I would if you havent, but there still seems to be something else wrong since you are losing everything, have you checked all the basics? salinity, PH, copper, stray voltage?
try putting in a polyfilter pad to pull any chemical issues out, and if you dont have a grounding probe get one just for the heck of it. just some ideas
