I have not tried this but the last time the ice on my dock was moving around I thought it would take out the hole dock. So I was thinking ahead for the next year and bought a 40 lb. sack of salt. I would pour around posts so ice would melt there first. Small amount of salt like that would not hurt a pond. Just my 2 cents worth of advice.

61 acre water shed lake. bass, channel cat, black crappie, wiper, walleye, redear sunfish, blue catfish and bluegill. To many bullhead and common carp
