Help! New Pond Issues

Subject: Help! New Pond Issues
by Paul17357 on 29/4/2019 18:47:08

Hi All

I wonder if someone can give me some advice please

I set up a pond last October and so far so good, however my water parameters seem to fall out of the scale of what is deemed normal.


Ph 8.6
NH3 0.036
KH 13 degrees
GH 18 degrees

Tap Water

Ph 8.4
KH 11

My question is should I be worried about Ph, KH and GH?, and what would you recommend to reduce these parameters?

Pond capacity is just short of 2000L

Also I have read a lot of on carrying out water changes, is it recommended to change 15% of water weekly?

The pond is a mixture of plants and goldfish
