Pond Heater

[420benz]

When the water was 35 the air temp was 27 at night.Both of my bird baths were frozen. The temp"s that day went up to 46 by 3:00. It has been raining for the last 3 days. This is the Water temp now.
Just remember the pond is only 19" deep 600 Gal.with a 13ft. long surface x 5ft wide.

The pond is quite shallow, now I am wondering if he might need a heater especially w/those fast temp changes? Or maybe not have so many water falls going at the same time? Never dealt w/such a shallow pond before myself.

What are the problems with having a shallow pond. And having 3 waterfalls.

Well nothing when it's not real cold. The issue might come when the current of the water moves the colder water above down below where it might be a bit warmer for the fish. Maybe turn off 2 of them and let only one continue. Perhaps someone else may have some more info on this subject w/shallow ponds in cold weather?

We will get Temp's in the low 30's. but only for about 2 t0 3 hours. Depending on how much liner is left around the pond i will try to get about 2/3 inches.

Your water temperatures shouldn't be fluctuating that rapidly, even with a shallower pond. Where are you measuring the water temperature and what are you using to measure?

The biggest issue is the stress on the fish. They are able to adapt to the temperature shifts when they happen slowly. But you're reporting some really fast shifts.

I take water from the center if the bond just off the top

I hope I’m just misunderstanding....... You “take water from the center.” Are you measuring the temperature of the water when it’s in the pond, or are you removing water in order to get a reading?

No That thermometer is floating in the center of the pond.Is is 7" long and registers the Temp. 7" below the surface.
