How big is your tank?
Do 2-3x a week water change, 50% etc, clean off all you can each time, turn lights off for 3 days, disconnect CO2 during this time, add Excel at full lablled rate after each water change.
You may do a daily water change+ Excel+ blackout for 3 days to really beat it back good.
However, you need to really work on CO2...........
DIY CO2+ high nuke light?
Excellent way to culture Rhizo........
You cannot induce it other ways, at least I never have after 15 years.

Ferts are not the issue.
CO2 is/was.
While you might have plenty according to a test now, did you test and did you pay attention to the tank like this poor to the algae bloom?
Once induced, the algae will often hang on aggressively, I might say literally, for dear life, and adult algae are much much tougher than spores......even if you correct the normal parameter issue that induces the spores.
So you have to be more aggressive to get rid of what is there or/and more patient.
Then keep up on things in the future.
Even if you reduce the photoperoid, you still have an insane amount of light.
Your Achillies heel is the DIY CO2.
Do more water changes for now, do the blackout + Excel for now and then do 2-3x a week water changes and cleaning/pruning.
It's not a hard alga to get rid of, but requires more work than some seem to think/want.
There is little trick to algae other than providing good consistent conditions for plants.
More light= more CO2 demand= less stability, harder to maintain and keep up on but faster growth.
You'd be much better of using 2x 39W T5's for this tank.
There is no plant you cannot grow using that and it's 3x less light.
Add Gas tanks for the CO2 rather than too much light.
$ much better spent.

HC is low light plant.I've had my run in with this algae recently as well. It doesn't seem to vacuum easily and attaches to my plants and substrates pretty well. I may need a stronger vacuum/suction I guess.
I think high light is definitely a problem. I have a similar setup but I use pressurized CO2 with a drop checker that goes from dark green to yellow/green by the end of the light period, which is about 8 hrs. Riccia and all plants pearl like crazy. I dose modified EI (modify dosing depending on need).
I will try the suggestions made here by Tom. The reason why I got the high light to begin with was to ensure that my HC grows low to the substrate. Would it still grow low with only 3WPG?
I guess time will tell.
Consistency for one, stability, adjustability.......why spend $$$$$$ on light then go cheap on CO2?Hi Tom,
Why would a pressurized CO2 system help solve this Algae problem than a DIY CO2 system?
Thanks.
