I didn't expect any problems with painting my kitchen. The house was all closed up & the AC running. I have to finish the job, so I'm doing just a little at a time at night when it's cooler. I had to shut off the AC & skimmer,& open all the windows until I can't smell any paint fumes. I'm using water based paints. The skimmer looked like a Mr Bubble bath! That won't happen again.It was bad. I literally removed a film of what appeared to be paint from the skimmer cup & micron sock. The fish could care less but the corals didn't like it one bit. What was I thinking?:smck:
