so the visual indicator would be nuisance algae?

I don't do anything.

I have tested for phosphates in the past and run phosphate removers but I never noticed a difference in the test kit results when I did so nor did I notice a difference in the tank inhabitants... so I quit.

I'm pretty sure I have phosphates and nitrates out the waazoo but until my corals start screaming for help I won't do much about it

Maybe you should have an option for algae scrubbers, although I suppose that could fall under macro-algae even though it is micro-algae?

I had an algae scrubber running, although I recently took it down due to a bunch of plumbing changes I made for the new fuge. I am growing macroalgae, (several kinds), and also have a bag of GFO in the sump. The macros will also serve as fish food.
