an air stone is the best way. yeah, over 75o or so you need to push air into the
water. kmart air pump is fine for that sized pond. Ingrid

Besides plants, is an air stone the only way to increase the oxygen?
This is the first full summer for the pond and it is HOT. Is there a
danger zone temp where water HAS to be cooled or air MUST be supplied?
I don't have electicity out there yet. I could run the trouble light
out there and throw in a small aquarium stone i have, but it would
have to be during the day when no one else was home.

This is a 60-70 gallon job and I have 2- 4 inch goldfish and about 30
toadlets.
