I had a chance to tear down and clean some pumps and powerheads. The only rust I found was a small amount on a magnet in the return pump. I have ordered a replacement part and cleaned out as much rust as I could. I can't go without a return pump for the time being.
The only other thing I can thing of is some of the acrylic projects I have put in the tank lately. Maybe the solvents used to bond the acrylic weren't fully cured, but that seems unlikely given the volume of solvent used and how thin the items bonded were.
I decided to do a few big water changes over the next few days, and hopefully that will clear out some problems. I think I should probably turn the carbon back on tomorrow, what do you think?
