      To glue or not to glue? (pond/tank construction)

      OK, so it is not a traditional pond on the sense that it uses dirt to make the form. 55"(w) x 91"(l) x 50" avg on a 15 slope



      I am installing a 45 mil EPDM liner for a koi tank to give a larger area for room to grow but also to power my GH Aquaponic system.

      I thought I would just drop the liner in a be able to fold the corners, but it is more cumbersome than anticipated.

      Question is this: I am not worried about aesthetics for this is a temporary solution to get my greenhouse producing. Can I fold the liner and have the weight of the water hold the liner in place, or do I need to make a proper inside corner and glue.

      To late in the day to get a proper pic of liner in place, but can do in the morning if needed.

      Adam.

      You can practice with a piece of paper and a box like this guy does. Makes neat corners.
      (I'd ignore the part where he dumps gravel in the bottom. )

      Thanks for the link, it was not technique I employed, but it gave confirmation that I could achieve a good fold without gluing.

      Looks pretty good!
      Several small folds will usually collect less junk than one big one.

      Only folds are in the corners and they go to the backside of the face that is showing. The weight of the water holds in place (that is what I am hoping continues to keep happening.

      I filled up past 1/2 of my penetrations and holding firm. I have started to tie in my Radial flow filters. First one is tied into my SLO (solids lifting outlet) b/c I did not want a bottom drain penetration.

      That will flow into my 2nd barrel which will combine with a surface skimming to then feed into my SUF (Static Upflow Filter) and then to my MBBR.

      I am kinda surprised that no one mentioned / suggested a pre-formed liner for this application?

      Don't know the time frame for obtaining such a thing, but, this was also an exercise in can I build it to work how I want w/o ALOT of headaches.

      About 900 in it with materials purchased PLUS another 150-ish in parts already on hand.

      So close to a dollar/gallon.

      Probably because he already had the liner and that he lives in Mexico. Becomes international shipping regs in play.

      Sorry, I missed the "nuevo" (New)!lol Still, didn't you already have the liner before you began this thread with the pics?

      No, liner was purchased at the same time the lumber was to make the frame. I needed to have a way to get gravity to work with me so that I could maintain flow in the event of a power outage. That is why I am so far above grade. It'll make more sense once I get the grow beds online for my greenhouse.

      Up to the fill line and things holding on the pond.



      Not so much when I has glued fittings on the live side, but thought I could "cheat" with silicone only after the valves.



      Let things dry out and glue thing proper tomorrow.

      Back to the drawing board. My water levels are spot on to where I set them to be. The SLO has phenomenal flow, and I thought I would be golden. I now have a reason to learn about physics and have a real world application to solve instead of when it was introduced to me back in college and did jot care enough to pay attention.......

      Guess I am back to digging to lower everything and try again to maximize flow b/c the penetrating through the pond are not moving...... (or do I prepare to eat my words?)

      I'm not sure what SLO stands for... but maybe show us how the water was designed to flow from the pond and
      through the filtration and I'm sure we can help as someone has probably done the same thing.
      And don't feel alone about things not working out exactly how you saw it in the design phase... most have been
      in the same boat!

      SLO - Solids Lifting Outlet --guess the easiest way to reference would be a retro drain. It is PVC with holes/slots drilled/cut into it and as the water exits, it pulls solids with it for removal by a swirl filter, radial flow, or mechanical.

      So what "physics and have a real world application" are you trying to solve?
