Hi all,
@AquariusPeter, honestly you need to concentrate on plant growth. Plants need light, it is their fundamental requirement.

Just think of it like triage, you are worried about the cut on your patients finger, while they are bleeding to death from a severed artery.

Hard water, I'd add sequestered iron regularly, several times a week.
Trim infected stems/vacuum out all blue green algae religiously.
Whack up the light intensity but don't illuminate the tank for more than 8 hours, as an experiment.
Add loads of floating plants, lots of different species.
Add a yeast and sugar 24 hour CO2 system.
Forget about macro nutrients until you get good growth, and ignore light elimination, it damages plants as much as algae, just give plants the basics, light, CO2 and in hard water, iron.
Only advice, each to their own.
