Help me.

My fish are dying at a rate of 2 - 3 per day. I don't know exactly why.
But I suspect it is a combination of temperature and pH. (pH around 8.0)
How I don't know...

My pond is in full sun and can get quite warm above 80F easy. But now the
pond is cooler sense the outdoor temps have become more tolerable.
Anyway,
I noticed I was loosing some fish. I tested the water and everything came
back OK except the water hardness, and pH. Both were way high. like a pH
of 8.0. Ammonia and nitrate levels were great. Hell, I've even noticed
the
string algae that started to grow dropped deader than a hammer as well!!!!
Something is in my pond water and its killing my fish.

Any ideas? Can temp cause a high pH level? Should I make my pond deeper
because its in full sun and can get quite warm? The current depth is
18-24
inches and approx 250gal. I had about 20 goldfish averaging 3-6 inches in
length. I'm down to about 8 and they're moaping around like the grim
reaper
is on their shoulders.

You say your params are OK. Is your ammonia zero? In warmer water, you'll
tend to have less oxygen. In a small amount like 250 gallons, you are more
suscetible to swings in chemistry, and the fish are more at risk. If you are
losing 2-3 per day...how many do you have in 250 gallons?

Are there any outside issues? Chemicals being sprayed, etc?

Are the plants OK?

Are any other critters dieing?
