Muriate of potash, 0-0-60, from any nursery/garden center. I just grabbed my
box to confirm price.. 5 pounds for $4.99.
5 pounds will last you multiple seasons!
Try it.. it should help.
Almost forgot.. dose is one ounce per 1,00 gallons of water every 2 weeks
for 3 doses!
Let me know how you make out. You should see improvement following the
second dose, unless other elements are lacking.
Happy ponding,
Greg

Thanks all for your response!

Greg, can you expand some more?
Are you suggesting that I add potash to my pond?
Where do I buy potash from? The least expensive approach of course.

You are right though because my string algae are totally out of control,
yet
my WH are not doing well, except in the veggie filter.

Try adding potassium (potash.. 0-0-60) every 2 weeks for 3 cycles.
I have hard water, pH of 8.2, and the hyacinths didn't do well either.
Once on the potassium the higher level plants outcompete the hair algae
(which loves higher pH BTW), and the hair algae's growth slows way down.
My hyacinths then bloomed like crazy. They may, in your case, be lacking
other essentials, unless you do routine water change outs, in which case
that shouldn't be a factor.
Happy ponding
Greg
