I read this post and the original one posted awhile back, I see no mention of a
filter except plants. In addition to 9 fish in 500 gallons she also has
tadpoles and snails. That many fish, regardless of size, puts a heavy load on
the ecobalance of the pond. Unless she had a 500 gallon filter, water quality
will suffer and the fish will start to die off until it comes into its own
balance, then it will clear. Telling her a UV will solve her problems is not
giving her a fair assessment of what she is dealing with. This is a new pond
and it is overstocked.

I don't think that's a fair conclusion. Inches of fish is far more
important than actual numbers as well as the amount of food being
given. As to the filtration, it seems more than able to handle the
load, with lots of WH, lava prefilter and reasonable aeration. If the
picture and description still holds true.

This water would probably be green without a single fish in it.

Add a UV, see your fish again this week. Keep on eye on your water
quality and change 100 gallons a month... fill the tub with WH,
protected from the fish.
