I think I am having an issue with EI dosing.
My plants have not been growing for a long time. Some step plants that I should be trimming to keep from taking over have not grown more than 6 inches tall. I have been dosing with liquid fertilizers but the plants did not grow well. One that was sold to me as L. aromatica (which I am not sure its a ludwigia of some kind) seems to have K deficiency, even though I was dosing k. I tested the water and it was stripped of NO3. I decided to do EI dosing with dry fertilizers
It seems the BBA loves it more than the plants do. One week into dosing and it seems BBA which I thought I had eradicated has made a come back and may take over my tank. I figured the plants would suck the nutrients up faster than the BBA, that does not appear to be the case.
Should I wait it out and hope the plants start sucking up the nutrients soon or should I be looking at changing routines?
NO3 ~10 ppm
KH ~9 dkH (I know its high, but Im trying to get it done. Not sure why it is so high.)
GH ~8 dkH (same as KH)
pressurized CO2 (KH 9/ PH 7.2 CP2 should be ~17-20 ppm)
PO4, I do not have a test kit for that. I have to order it. Hope to get it soon
Just did the first weekly water change since starting the EI dosing. hope things improve.
