I just checked the pond chem stats.

GH 75
KH 300
ph 9
Nitrates 0

Looks to me that the ph needs to come down and that that may be contributing
to the problems of the WH.

How do we lower the ph effectively in a cement pond? It is in fact higher
than usual, generally, we have been in the 8 range.

Speak, O pond muses.
