Okay thanks for adding the thought that potassium is unlikely to be too much and cause harm. I can "experiment" a bit more freely with that in mind.
A question on the calculator. I have looked at it but was unsure how to read it. I assume it expects one to be dosing Nitrate and phosphate when looking at the dose of K2SO4. So my question was If I was high on both of those (I am!) can I safely/ simply dose a one for one of K2SO4 to replace the potassium not dosed by dropping both N and P. I've been doing that for about a week now and see no change in the one plant that I am really working.
Situation? I have a 20 long with too much many weeds but it works well for me to use it to watch my nitrate and phosphate. Those two tend to be way too high in most of my tanks so the little tank is a better place to try to sort things out a bit. Red myrio, Java fern, Java moss, narrow leaf sag and different swords seem to grow very well. But at the same time, I have an anubia which does so little that algae tends to take over. Watching progression closely, I now see it tends to get what I thought was black spots of beginning algae, then develop yellow spots which progress to black holes which fall apart and the leaf dies. New leaves come on and seem normal for a time while the old dies.
I was working it as a potassium def. but not seeing progress.
Very hard, alkaline water Nitrate 20+, P of 1.0+, injected CO2 which should be plenty and other plants grow and spread but this one does this. Try not to look at the red and blue. Too many small fish to keep them out of the picture.
Open to suggestions, hints or even wild guesses!
Maybe it just isn't trying very hard?
