The Fluval heater in my 50-gallon tank broke right down the middle. Not sure when, I just woke up this morning to find it that way. Maybe one of the plecos hit it wrong.

I've removed all the parts and broken glass that I could find, but I'm concerned about the possibility of dangerous chemicals from inside the heater entering the tank. I saw some rust-colored water come out of the broken tube while I was removing it.

This tank just recovered from an ick outbreak last week, I don't want more fish problems if I can help it...any advice?

I'll replace the heater first thing today.
