I had thought that might be it, but was hoping there was something magical
I could add to recreate the dramatic pearling I get after a water change.

That does make sense.

Actually, I normally forget to add the larger amount of TMG for at least
a few hours.

I've got 240 watts over a 75g. It's a mix of Tritons, and 5000K and 6500K
daylight tubes. (2 of each)

I want! I want! Actually, I do currently need to trim about that often.
My main thing is that I love seeing the solid lines of bubbles rising in
the tank. It just looks so cool!

Actually, I just noticed some evil blue-green algae on several clumps of
frogbit. It was just a tiny bit. I'll be keeping a close watch for any
more of it!
