Sorry you lost the other one Gary! Has that tank been in use previously for fish, etc. and any strong medicines where applied on it. Same question for all decor.
If not then other possibility is an un-cycled tank due to overuse of Prime or mixing Prime with API dechlorinator. Let me explain the "Nitro Yo-Yo Effect."
When you cycle a tank/filter, you have to let the bacterial colonies grow. In order to do that they need to feed and multiply. Prime and other ammonia reducers are very aggressive so to use them as a de-chlorinator before adding tap water to tank is fine; but to add them to tank to reduce ammonia/nitrites (as the manufacturers recommend) removes the bacteria food, so they starve off and die. Then the urea from frogs adds more ammonia but now the bacteria have to repopulate again, so in the meantime, ammonia levels rise. Then the aquarist (or frog keeper) test kit shows ammonia... OMG! So we add more neutralizing chemicals (Prime, Amquel, etc.) and so begins a series of mini crashes and your ammonia levels go up and down like a yo-yo. Also, your tank will never cycle correctly or take forever to do so.
My recommendation is to use Prime or whatever only once on tap water before adding to tank, and then let the biological cycle establish itself without chemical interference for a month (2 weeks if add Seachem Stability or similar). Good luck!
