Mom and I bought a new place 4 minutes from my sisters and 9 minutes from my son's..I'm so happy...It's only 5 acres(I'm living on 43 so it's a big difference)..but it's way out on a dead end road,with no one for a long way off,we won't hear people or cars much.. an occational tractor...yay!!! Only 10 minutes from a good sized city(Springfield,IL.)Now I will be close to the good stores again...:-)
Anyway...
I don't know a thing about koi or ponds and we just bought a house with a
koi and lily pond..It's supposed to have about 38 koi in it...I saw about 10 they
look to be about 8"-10",some orange some white and orange..it's dirty...about 15 x 15 she said it was 3 feet deep...I will ask her what other colors they are when we go sign the papers tomorrow..YAY!!!..Maybe I can get a photo of their backs,the water is to dirty to see them very well and I don't think they do much for the pond,it need part shade to keep the algae down correct?
I need to know basicly everything...Do I need a filter?
The place also includes(goes with it) about 40 chickens,and a cat that needs spayed... :-(
Here's my New Koi pond..I've always wanted them couldn't afford them then ended up with them..lol...Did I mention I was very happy
