Check your lights if they are tubes you may need to replace them
What are the nitrate levels?
Feeding schedules?
Using tap water?

These are all things that will effect your corals etc as well.

I don't want to start over either. As for your questions,
Lighting is LED. (Vertex illumina 1200)
At max 50%
Nitrate & phosphate is undetectable,
even after my massive scrubbing,
Have always ran carbon and started running GFO this last half of this yr.
other parameters are
CA 420-450
ALK 9-10
MG 1600-1800
PH 7.9-8.1
Temp 77

water is topped up with a 4 stage RO/DI and I've never let my TDS go over .005 and use an auto top off with a kalk reactor
Feeding schedules for the last yr and have been cut to a single feeding every 48hrs ( auto feeder) and I only use high quality low phos foods.
I also run filter socks to trap and extra detritus
And I know its not from lack of skimming due to having a deltec AP703 on this system and recently swapped that out to a bubble king 200.
So I'm at a total loss and this is going to be my final take at this battle before i call it and its a tear down

You are running a skimmer and thus your oxygen should be decent but how is surface agitation in your display tank.

Keep it simple - algae has 3 major variables.

1: lighting is covered by your LED lighting.

2: fertilizer which is covered I your supplements

3: Co2

So my guess is the tests are missing something.
