    I am building a new pond and I decided to fortify the border with mortar and flat stones.
    That part is fine.
    However, after I finished, it rained and washed some cement silt into the water. It was cloudy and then settled into a fine layer of silt.
    I'm thinking about hooking up my filter and pump with some fine material in it and run it for a few days, stirring up the water every now and then. Then clean the elements. I know I won't get it all out. Besides, soon it'll have organic silt and algea anyway.
    I can think of no other way besides draining the whole thing and then using a "wetvac".
    This pond is new. 1,450 gallons. No fish or filter yet. Though I have a filter and 2,000Gph pump.

    I would try it the way you suggested first, before draining. Can't hurt, right? Maybe get some aeration going to keep the silt moving.

    My plan was to run a pipe from the filter outlet to the bottom of the pond on an angle to keep it all spinning. Try to keep it all suspended.

    drain should not be needed. for a cheap filter medium can be white buffer pads used for stripping/waxing floors. about $5 -6 each. others who have come in to the same issue may have a better solution.

    Why not just leave it be. It will turn green soon enough. Any chemical alteration to the water has already been done.

    Isn't the sediment super abrasive?
    It has made the water super alkaline, too. As you said.

    Only abrasive if pressure is applied with movement. Same with ordinary Garden soil.

    I had tons of cement dust fly in my pond when we were doing construction when we were cutting hardi board. Also they were affected by steel filings, sawdust, cigarette butts, etc. Most of the fish did fine despite all of it. You may want to check the ph. Koi don't fare as well in high ph. My guess if you are not over 9 it should be okay.

    Thanks.
    The PH from the tap is 7.8
    The pond is 8.2
    I'll get out some of it, then I won't sweat it.

    I just ordered a pond vacuum. I've never had one before.
    It's an "OASE 57347 PondoVac Classic":
    It looks well made and easy to use..............I'll report later about that!

    pH of 8.2 is pretty typical in North American Koi ponds.

    My original concern wasn't too much about the media to filter it out, but for running all of that abrasive cement powder through my brand new pump motor.
    I got the vacuum, but I haven't had time to use it. I need to travel to Georgia over the weekend starting this evening.

    did your pond eventually clear up? I had a cement like silt on my pea gravel for my bog, which also made my water yellow. After 4 days still not back to normal. Wondering if I should turn off the filter as it may be continuously churning the particles around.

    I'm going to get some batting this weekend along with the waterfall pump to see if it helps.

    I use a cheap pump from harbor freight in the spring to clean the pond with the crate and then divert it back to my main pump hose after all the pond is clean .Picks up all the fine algae in the spring I buy the blue reusable furnace filters on top to pick up the heavy stuff and the quilt batting under it to pick up the fine stuff .It is worth the extra work involved ,plus my plants love the rinse water from cleaning it

    I used my POND O VAC today.
    It works great.
    It vacuums for a few minutes at a time, so it took a while. But it was easy and a real breeze to rinse out.
