Keeping the pond bottom clean/winter frogs
I keep the bottom of my pond as clean as I can. Last year all of my frogs
froze because there wasn't enough muck to bury in. What do I do about that?
What should I put in the bottom to help them make it through the winter? I
have a 125 gallon preform with airstones running in the winter and the fish
have overwintered fine for the last four years.
Thanks,
Anne
