Got the back glass cleaned of coraline at last. Oh boy that was a killer on the arms. I'll get to the sides this weeks.

So, with no PO4 dosing I'm still getting superfast growth. It's almost like nitrate is preventing the whitening tips I was experiencing, and the small amounts of traces are keeping the lush green color. I wish I could prove this outright but it's only my observation.

I'm switching out the skimmer for an internal filter in the sump. I want to test if it really is aeration that was my issue when I pulled the plug on the skimmer the other week. I can say for certain that it doesn't pull out skimmate, but it does a fine job at gas exchange. Did I experience a burst of carbon or oxygen limitation?

I also should be receiving a bag of goodies from CA within the next week. Let's hope the weather plays nice for shipping.
