    If you had the right medium in it. Sand pool filters are too fine, they would clog constantly.

    Agree, with Addy1 on the pool filter. You could turn the upper portion into a up flow bog and depending on what you wanted to keep would be all the filter you need. Addy, has a thread stickied on how to build this at the top of the pond construction forum.

    i have a 1500gph pool filter with a removable element that i can clean or replace. then i was going to use a waterfall box to make a secondary bio filter. thanks. i am new to this and any helpful hints would be grateful.

    What chemical is used to treat the wood you built the pond with?
    It might say on the labels that are on the wood or you can find out from the supplier.

    Copper is poisonous to fish and algae and the fungicides will cause you to have water quality issues.
    Your algae will suffer as well and algae is an important part of a healthy pond ecosystem.
    Pressure treated wood is not generally recommended for pond construction where the chemicals could leach into the water.

    the box itself will never come in contact with the water. the top trim will be spuce.

    Ok, Just was wondering if you were aware of it.
    Splashing water and rain runoff are also sources that could cause the chemicals to get into the pond water.

    -oh, it's not your pond.
    Maybe post a picture of your pond when you can.

    The treatment will be either ACQ or Copper Azole, .06 treatment for 2x and .15 for 4x. If you do build one like this just know those arent rated for ground contact and will rot quickly. Personally, I wouldn't worry too much about splash and runoff causing issues in the pond. That treatment is very light and the lumber drys out quickly. I built one like this years ago, back when treatment was CCA (treatment was higher as well) and it never had any issues. Might if the lumber was in constant contact with the water.

    I saw this photo when I was working on my pond earlier this year. In principle, my current pond design is similar but half of the pond is underground and the rest above ground was built with concrete and landscaping blocks. I about 2000 gallons. There is a Laguna MaxFlo pump supplying the waste water to the bottom of the bog and the water travels up to the spill ways on top. However before getting into the pond, I have a canister filter to separate out the large debris. Real happy with the design and effectiveness so far, pond is super clear and water quality is pretty much spot on. As others have mentioned, get the right substrate in the filter, as pool filter media were not intended to clear out crude like you find in a pond.

    Mitch, I was thinking to build a small structure in the pond to create a canopy of the net, If not PT wood, what are options?

    I don't know which wood species are available around your area, but have a look through this list for some options.
    Composite material is also an option.

    A bridge made out of pressure treated wood, wiped out my entire pond years ago (when I didn't know better) , every time it rained my fish acted drunk, until one day they all die
