green water
Re: green water
yeah the sludge is all round the sides of the pond and some of its like hair
Re: green water
The sludge is not good 
This harbours nasty anearobic bacteria that will not help your koi and water quality one little bit. If you dig out a handful, it probably smells like rotten eggs?
Your pump is not pulling the water thru to the filter correctly, and the dead spots in the pond (ie poor water movement) are where food and Fish poo build up to form sludge.
The Hair like stuff may well be remnants of blanket weed, which again indicates build up of waste (Nitrate and Phosophates) in your water.
I'd be inclined to clean out the sludge (pond vac). This may entail putting your fish temporarily in a well areated paddling pool or tank. Then Position the pond pump and the returning water from your filter so that you have a good flow thru' of water, and avoid dead areas.
