People with plenty of Nitrates in the water also dose K2S04 as either a usual macro or in a water buffer with each weekly water change.
Which plants do you have?
Thanks for all you help. I have the long thread algae, staghorn, and the type that is a green, fuzzy carpet.
For plants, I have

1 large moss ball
3 crypts that got overcome by algae and are now small
Echinodorus Ozelot Red
