EI Dosing help with no KNO3
My tap water has all the nitrates I need (lucky me) so I don't add any when dosing. I'm getting my BBA cleared up by still having issues with some plant growth. Most of my easy plants grow really well. Loads of various anubius, a couple different crypts, a couple of mosses, several different buces, a few different java ferns. My s repens stays alive but only get about 2 inches tall with bare stems and small leaves on top. Other plants have just barely hung on or dissappeared I tried to get things adjusted properly without the KNO3 but I think I had levels wrong and have just recalculated. I was dosing 1 tsp K2SO4 and 1/8 tsp KH2PO4 and on alternate days 1/4 tsp CSM+b, not sure how I arrived at that but now as near as I can tell the KH2PO4 and micro level is ok (maybe a slight decrease) but should be using 1/2 tsp of K2SO4 I think that will provide the 5ppm of K that I'm missing by not dosing the KNO3. Does this sound right? I want to get this close and run this way for a couple of weeks to see if some of the plants that are struggling come around.
92g tank calculating dosage for 80g
I think I have a strong medium light (It's an odd array of fixtures)
degassing water now ph usually around 7.6-7.8 right between the high end of the normal test and the low end of the high test. About a 1 point drop with CO2
KH & GH both 6
Temp 82 I'll be dropping it back to about 77 (ich is gone)
50% weekly water change.
I'd appreciate any input on these dosing levels.
