Q about the dosing regimen sticky
I need help understanding something:
The sticky sugests for a 75Gal tank:
For a 60~80gal
+/-3/4Tsp KN03 3x a week
+/-3/16Tsp KH2P04 3x a week
+/-1/4Tsp K2S04 3x a week
+/-15ml Trace 3x a week
+/-4-8ml Fe/Iron 3x a week
If I compare with Chucks calculator, it would give an amount of 9.07ppm Nitrate
He recomends 5ppm, and I've read somewhere that the target should be between 5-30ppm. So 9.07pmm is okay I guess.
For phospaphate, 3/16 chucks says it gives 2.11ppm, I've read that it should eb in the range 1.0 - 2.0ppm, but also read in this thread that up to 5.0ppm is fine as well.
For Potassium 1/4tsp by chucks gives 2.37ppm potassium, he recomends 20ppm and elsewhere I've read a range between 10-30ppm.
Am I missing something about potassium? Why is the dose recomended so low in the sticky?
