15 fish all under 9" mostly Koi

Water Hyacinths are browning and curling up at edges as is Water
Lettuce.....!
Although yesterday having read various postings on web I added 1 tablespoon
Potash

This dGH reading is worrying me ..what is it telling me?
Anyone have a solution please

Many Thanks

Regards
Chris




dGH is water hardness, and I don't think it is the problem. Mine is
about 55 (varies during the year) and my hyacinths do well enough that
I supply a local water garden store.

your pH is a bit high, but I would think it not enough to be a
problem.

The koi aren't eating off the roots, are they?
