So after creeping around this forum for about a week I finally made an account to post and ask questions! Spring is just around the corner and I’m planning on building a pond in my backyard. I’m thinking about a 10ft long 8ft wide and 4ft deep (maybe 5 at the deepest) so around 2000ish gallons, One of my biggest questions was pond liner. If I were to dig out the pond would I just put pond liner flat on the ground and put rocks to hold it down? or would I need to double layer it or have some type of tarp? As for filtration I was planning on a DIY garbage can canister with a large pond pump (Vivosun?) aswell as a small bog (I would just have to figure out how to build the bog up). I know I want to have koi (atleast I’d like to) but have been getting conflicting information about how many koi could go in a pond that size so I was thinking about having a total of 5-7? And wondering if I would be okay to start off with 10 or so until around the first year mark, at which point I’d giveaway the unwanted ones. I also was wondering about feeding, I have quite easy access to: Hikari Gold (and Staple), Aqua Scape cold water/wheat germ, and Tropicals Koi Crossiants. I was thinking about starting them off for the first year or two on mainly Hikari gold and Koi Crossiants with a bit of wheat germ sprinkled in (until winter time I’d do mainly wheat germ) and after the two year mark switching Hikari Gold to Hikari Staple. I keep mainly amphibians and reptiles but also have a few fish tanks, I know with fish tanks you have to cycle and do water changes frequently so how would it work in a pond? And when (once everything setup and running) could I add koi, would I be able to add them right, away or would I have to wait? does a pond semi follow the same rules as an aquarium in terms of cycling and water changes? I’d assume I could just use my Python and siphon maybe 10-20% of the pond water out and into my garden every 3 or so weeks and fill it back up with water from the hose (with a 3x dose of pond prime), But before I do anything I wanted to ask you guys knowledgeable with ponds your thoughts before I did anything. Thanks!
