Bottom drain diffuser all winter?
My contractor recommended that i turn off my waterfalls, filter, skimmer etc, but let the diffuser on my bottom drain run all winter long to keep a hole open in the ice.
Is this ok to do?
My pond is 3 1/2 feet deep, about 2500 gallons. Im in zone 6
Does anyone leave their BD diffuser on all winter? Is it safe to do so?
