You want to control algae and Chara really well in that pond with no bass, put around 5-7 pounds of tilapia in it as soon as the water reaches 65F. Since there is no bass present maybe you can use small tilapia 2"-5". Blue tilapia work well but others are also acceptable. Check with local aquaculture or aquaponics guys who often raise tilapia indoors. Craig's list is a good place to start searching.
