Water garden help please?

Ughhh...Garden ponds are great places to breed mosquitoes. I suggest looking on Craig's list or waiting till fall when this stuff goes on sale. Koi limit the amount of plant life available to be grown. Simply put: koi eat some plants. A koi pond should also be larger because koi get quite large despite the size of the pond, it is recommended that a koi pond be no less than 1000 gallons in volume, the bigger the better. It also needs to have an area of the pond at least 3 feet deep, 4 - 5 may be better.
