    ^The pressurized vessel as the last (sand) filter in my filter cascade (as I showed above) has the function not only to catch up the fine particles but providing the possibility to backwash the sand every week or so, thus spraying the surrounding garden with the water containing the fine particles (actually the fish shit) whether it is with nitrate or ammonium residua or whatever...

    And the garden likes it...

    So the waterfall is running, and with all of your suggestions the water is clearing up a bit.
    and it is time yo tidy-up the area. I got tired of the dogs walking in the mud and walking all over my just cleaned tiles.
    So it is grass time. I was going to do it myself, but every place I went to buy it, they wanted to do it themselves, and it was so inexpensive , I let the,. The whole thing cost $70 usd. including a nice thick layer of good dirt under the grass.
    If you can find it in your area the dirt brand was "Diamond" and it came in green bags, It is good stuff. I will go buy some more later for my flower beds, and will post a picture of it.
    They striped the old grass off,

    laid the grass down ( Non Noy I think it is called) and rolled the heck out of it

    and all for the equivalent of $70. I am beginning to like Thailand more LOL.
    Notice how I am holding my beer stomach height? That's so it would not have far to go. LOL

    I did stump on the grass a bit, so I can honestly say I helped.
    The sooner you fall behind, the more time you have to catch up.

    Before we left the US we shared a container with others in the area and shipped a number of large boxes with clothes, kitchen equipment, and some tools, included in one box is my self propelled craftsman lawnmower.
    I have it all figured out. tie the lawn mover with a rope to a pivot post, every time the lawnmower goes around the rope wraps it's self on the post becoming shorter and moving the lawnmower close. What can go wrong? LOL
    It was supposed to have arrived already, but I guess the blockage of the Suez Canal slowed things down. No worries as we did not really need any of it. Though I do miss my Kitchen aid artisan stand mixer, Ninja airfryier/ Foodi grill, and cast iron crock pots. Friday, I start construction of a 13x18 ft utility room to house my toys.
    Nothing fancy , since it is under the house and all I have to do is put up the walls, a couple of windows, a door.
    I will start a thread about, it should be a short thread. .

    No construction in Thailand could possibly be captured in a short thread... if it is a short thread, then sure you're hiding mistakes and disasters..

    Made a little airlift pump for the pond at my brother's house this weekend. Had never tried one before, but boy does that thing pump...
    it's very simple, takes maybe 15-20 minutes to make and basically what it does is to lift water from the bottom of the pond and pump it out at or above the water level.
    You can use it purely as a circulation pump, which is valuable when having koi. Or you could lift the water up and drop it into a filter before it flows with gravity back into the main pond.

    See the first outlet. This is before attaching the airlift at the other side inside the pond.

    Here I switched on the air. The volume coming out is much bigger.

    And a look at the pump.

    Basically, it's a 4" pipe that sits about 5cm above the bottom of the pump.
    The top is a T that has a 1.5" side which is the diameter of the inlet to the sump.
    In the bottom of the 4" pipe I've attached an airstone with a tie-rap and that's it.
    I'm using a small air pump that runs 6 air stones in total. 1 inside the airlift, 5 others spread throughout the sump and pond.
    I had 2 airstones inside but disconnected one because the pump could not keep up with the volume going into the sump..lol.

    You could just fix this to a side of the pond and the water will start circulating a lot more than before, helping oxygenation as well.

    Here's a drawing of a pump.

    I used a T with open top. This helps to make the water flow faster as the air can escape upwards.
    Also, in my setup I used a T with smaller diameter, but that's purely to fit the outlet. Same diameter would again be better for flow rates.
