Wow,75 tor & friends . Sounds like you might need to thin out your stock in a year or so. Wes, did say he wants a pond in his backyard to growout his bambusa and some tor. These tor will blow away most other pond fish when they get some size to them in beauty and feeding fun. I am just getting my ponds going again and hope to have my fish with some size in the near future. Oh, never trust a tor to not jump out. Sooner or later they try. All my ponds are covered with mesh now. I think your pond is covered, yes? I guess your clear water is a result of uv and your algae on sides and bottom. I have been running plant filters exclusively since 95 with aquatic swamp fern as the current media, but I am changing plants now looking for a less messy plant. I have a few I am working with. I am going to try a pressurized filter filled with K3 or similar media for algae and solids removal soon.
