I have java fern (windelov) but it doesn't matter which Java fern I try it, always gets black on the ends. The rest of the tank is ok except for the anubias which turns brown and then melts in spots. Someone said I might be short on Potassium. I am using EI for my 46g and everything else is growing very fast. The stuff on the fern almost looks like burned leaves. Any idea what might be missing?
I do get what I call sludge on the gravel and in the filter. If it is diatoms it does look the same on the two plants. I am going to test my tap for silica to see if that is why the brown sludge. Not sure what to do if the tap has to much silica, for I added the pelts for that to the filter and they turn dark brown in a week. R.O. is expensive and a pain to do because you then have to add back in. What to do next?
O, O, 6 ph 6.5 80 degress
