Hi all

Newbie here please advise.!!

Pond is about 9 months old with a 55Gal Biofilter + (UV installed this week)
Plus a newly setup Veg filter 300gals
Plus 2 waterfalls (in and out of veggie filter) for oxygenation
2000 Gals in total

Water Temp 60 degrees (Noon today)
Amonia= 0
NO3= 0
NO2= 0
PH= 8.5

How high does your pH tester read? If only to 8.5, perhaps it is much
higher? Very few plants can take the nutrients they need out of the water
at 8.5 and up. They actually become less effective removing nutrients after
8.0, but can manage, also filter bacteria don't do as well either.

Salt 1% or 0.1%? Big difference, every plant in your pond is gonna succumb
if it truly is 1%.

How old are all your test kits? ~ jan

dKH= 4.5
dGH= 21.....................????!!!
Salinity= 1%

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
