Well, it's like this. Only blue so I think it's essentially the same. Not sure the wattage.
Anyways, I live in AZ and I've been watching the water temp at it's been pretty safe so far (73-78 degrees). But yesterday it dropped to 67 degrees. No bueno. So I decided to throw the heater in just for the night and it kept the water a safe temperature.
My question is this (don't I have a knack for drawing things out?): will this heater be safe? I was concerned about him burning himself or gnawing on the molding and getting sick? I've heard of people using a PVC casing, but I lack both PVC and a power drill so...yeah.
Any tips would be nice! I recently upgraded from a 10 gal to 20 gal if it helps.
