Hello everyone,
I am planning to build a 1000 gallon pond to house a couple Koi for my son as he has taken up an interest with fish (hes only 10 months but loves to stare at koi in a koi pond)
Im a little lost on how to pull this off, I am not massive on DIY but I am a good learner.
From my understanding, ill dig a hole, 5ft by 7ft 3/4ft deep to house just over 1000 gallons.
Ill put down an EPDM pond liner (is this any good?: https://thepondpeople.co.uk/cat/pond-liners/elevate-pond-liners/?utm_source=googleads&utm_medium=cpc&utm_campaign=21108999575&utm_term=epdm%20pond%20liner&utm_content=%7Bcreatives%7D&gad_source=1&gad_campaignid=21108999575&gclid=CjwKCAjwqubPBhBOEiwAzgZX2iXCA7U0zr1jeoNbLaAh96pCnIojVbNSjoxT4vVMaXgsJjE4LMh5OxoCdhIQAvD_BwE)
I will then get a bottom drain, which will connect to a DIY barrel filter which is in the ground next to the pond? Level with the water is that correct? Then the water can travel up the pipe into the barrel filter?
The barrel filter will then be connected to a pump that pumps the water back into the pond again? And the pump should be rated to move 3/4x the amount of water i actually have?
I am confused on how to attach the epdm liner to the bottom drain, I am unsure if my plumbing would be correct, i actually dont know how to ensure the plumbing would be water proof (do i seal the pipes with something?) and I have no idea how to make a correct DIY barrel filter.
I know I may sound naive but id love to be able to do this for my son.
I have attached a photo of the hole I am planning to dig. If its wrong I am happy to make changes.
