Last night I was moving my flexwatt over a bit and noticed a strong urate smell. Upon closer inspection I found urates on the flexwatt. I removed it and dried it well. I searched for a source but found no obvious holes but I did notice urate in the unused right side temp probe slot so maybe from there? The flexwatt seems fine ave even after going overnight was running correctly so I believe it was unharmed.... Gonna search in Loki's side tonight. Once I find it what are my sealing options? Will hot glue work ok? I know tape is a no no inside the tank. I thought about heat tape outside the tank but will that reflect heat back at the flexwatt?
