i just finished a couple of weeks ago digging my new mud pond. its 5-6 ft deep and has about 2 ft of water in it so far.i have a few questions. being fall there have been many leaves fall into the pond , will this hurt anything? being a freshly filled pond ,how long should i wait to add the fish i am wanting to winter in it (25 fish)? i will be adding a fountain or aeration to it but havent decided which. most likely aeration. im in middle east tn so the winters can get cold but they dont stay below freezing for long periods of time most years. so any help or advice would be great.
