I may try to call and get it swapped out I still might have time I dont think it has shipped yet.Keep running carbon and change it often. I'm sure it was the loss of the UV that caused the set back.
26 watt is pretty undersized for your tank unfortunately. The manufacturer's size recommendations are for completely different applications. Hopefully it will help but it's less than optimal. The 57 watt would have been great. Jaebo also makes a 55 watt that is much less expensive, but still works well.
Thanks for tip about Jaebo as well
