This is weird. Twice now I have looked at my tank with the full LED's and T-5's blazing and the GHA looked enormous. Then, later that day when the lights were just dimming LED the GHA looked like the normal nuisance with which I have been dealing and not huge.

The first time I chalked it up to GHA angst. Now, I only have two theories. 1. GHA somehow "grows" in high light and then later that day in lower light recedes or 2. I am having a GHA-induced psychotic break.

Any other theories?
