If I believe my test results I usually have between 20 to 40ppm nitrates, 2 (or so) phosphate and around 100ppm potassium. I do overdose potassium but that was under high light for giant hygro (sorry don't have proper name). So not sure on that potassium reading.
BBA has been a pain. Very little green spot algae. One plant has some hair algae.
Since sorting CO2 injection, dropping lights to 6 hours, increasing glut dosing and possibly help from fish/snails; the BBA has reduced over last month or two. First couple of weeks nothing seemed to happen but now I can see a difference. Recently swapped back to T5HO (from LEDs) so will so how that goes. Running lights for 7 hours.
This tank used to get green spot algae on one side that had a little natural light.
The best planted tank I did was one where I was away for 6 months. That had no algae at all.
There was no ferts dosing, never replaced bulb for years, never knew what I know now eg on water changes, no co2, gravel substrate with ugf. I can only guess I hit some balance that the plants liked (although I wish I could go back in time and test ph to see what the swordtail fry were swimming in).
How do you test your K? My test kit doesn't work right.
I have heard a lot of stories about how increasing PO4 got rid of green Spot Algae.
