How to build trapal koi pond

Build the trapal koi pond frame it is up to you what materials are you going to use bamboo or wood. You can also dig the ground if you prefer not to build trapal koi pond frame. I highly recommend this since it will make your trapal last longer than raised koi pond design.
After you are done with the frame or dug a hole in the ground check the grounds if there are any sharp objects like stones, nails, roots of the trees etc and then add protection like carton or newspaper.
Now layout the trapal in the frame or earthen hole koi pond fold each edge to ensure that there are no sides that are stretching
After they are now in place secure them with u nails to stick them if you are using bamboo or wood frame for the earthen koi pond place stones to each edge to hold the trapal.
add water and then install also your filtration system my suggestion is used airlift filtration system it is cheaper in power consumption, your safe for any electrical shock and does not clog up like the submersible pump.
After your filtration system is installed run it for a week before adding your koi fish.
