What I want to do is use a 6’ diameter galvanized stock tank as the main part of the pond and the black plastic premade pond liner as an elevated bog filter. The water will return to the main tank by way of the waterfall.
I am going to tuck it back into this area in the garden, I figure I will need to excavate 6-8”, fill with 2A limestone, tamp and level the area before I put the tank down. The bog will be supported by a base built on cinder blocks that will also have a compacted base layer of stone underneath it.
Is this black plastic the PVC I should be avoiding? If that’s the case I will probably abandon it and search for a new container. I got this for free so I have no attachment to it
Referring to Addy1’s thread “Bog Building” the sizes of these two containers fit with in the suggested range. The stock tank will have no more than 390 gallons in it, the upper pond has 22.5 gallons so by volume the bog will be about 6 % of the volume of the main tank. Surface area wise the stock tank will have 28.3 square feet the, bog has about 7 square feet so 25 % of the surface are of the main tank good to go right?
I don’t plan to have large fish or a ton of fish so I am hoping this will be sufficient to filter the pond. I have heard conflicting things about the galvanized tanks leeching zinc and killing fish so I am going to coat the inside of the thing to be safe. Any products out there that are suggested for that? I am currently thinking about using a grey flex seal, I would really like to use clear and keep the look of the steel tank but I think grey would be better as I will be able to see if I miss any spots or notice if it starts to fail down the line.
For a pump I figure I need about 200-250 GPH to circulate the water through the bog. The weir on that plastic pond liner is 4” from something I read, to maintain a waterfall I think need 100 GPH for every inch of weir so I am looking for a 400 GPH pump. Am I correct on my calculations for the for the pump. I plan on using a submersible pump to keep the sound of the pump to a minimum.
