HEy
I have a customer who has an approx 300L pond, it has no filtration (apart from a small water fountain), she was maintaining the algae by adding algae fix to the pond every fortnight and all the was well.
Anyway she stopped adding the algae fix as she got busy, so its been about a month without it, now the algaes quite bad and all the fish ( 5xlarge comets) are all dead.
I tested the water pH is at least 8.8, ammo 0, nitrites 0, nitrates 0, phosphates 0.5
Now im am asumming here the pH has killed the fish.
I didnt know what to tell her to do to the pond to lower the pH, as ive never come across a pond with such high pH.
Any suggestions???
