Tunze Osmolator pump seized, WD40 reside safe for reef tank?

Ok, but Rustoleum has fish oil in it!

I knew when I responded to this thread I would jinx myself. I've gone through several pumps in the 7 or 8 years. Your post made me reflect on the fact that the current one had "lasted quite a while". Well sure enough...it died yesterday! I knew I should have knocked on wood or something!

I replaced it, the new pump seems to run slower, and I am eventually going to have to strip back the main wires, as there is some corrosion on them. I of course used WD40 on the wires

I would like to know why my halimeda has been dying off. I removed most of it this morning, as my tank was cloudy and I had to a water change.

Hi Tim! long time to talk to. We should get together soon and talk tanks. Need any hammer coral.

I would like to know why my halimeda has been dying off. I removed most of it this morning, as my tank was cloudy and I had to a water change.

First guess is calcium and alkalinity. If either is low then that could cause halimeda to do poorly. If that's not it then lighting spectrum (old bulbs?) would be my next guess.

HTH,
Tom

If theres an oil slick, just call BP and see if you can get a little dispersant. LOL I know I spelled that wrong.
