Koi fish are addictive

[IRescue452]

I went and put the 3 smaller Koi into the extra 10 gallon tank. They are only about 4 inchs long. I hope this will reduce the cloudiness that keeps happening. The other 4 that are about 8 inchs are still in the 55 gallon tank. I am also vaccuming the rocks every day. So I hope that helps. SUggestions are welcome. I am learning as I go.

You need to learn how to cycle a tank (not with the fake cycle stuff sold on the store shelf). Cycling grows good bacteria that keeps the ammonia levels down. Normally you do this before you get fish. You'd need a chemical testing kit. Unfortunately your tanks are so overstocked that there is always going to be too much bad stuff for the bacteria to keep up with. I suggest you vacuum the gravel daily and change a good amount of the water, but rarely clean any surfaces in the tank, especially not the filter unless its clogged. The good bacteria will live on surfaces.

Here's one of my favorite koi I'll never own http://www.majestickoi.com/buyKoi.php?id=184&page=5
