plywood sump with pond liner

[coldwaterreefer]

what do people think it can be done? than you can make your sump any size you want up to 8 feet long for soild sheet.

It could probably be done. However, I would think it wouldn't stand the test of time, as invariably there would be a leak or the plywood would fall apart from somehow getting wet.

I am looking for some pondliner for a pond this spring. Anyone know where to get it cheap?

Brett if I was doing something like that I would use some blocks that lock together instead of wood. Especially if you want to do it deep.

They seem convinced. It sounded like the key was the swimming pool epoxy paint to seal it. You try it first, and tell me how it turns out...:wink:

rubber roofing material (for flat roofs) can be used also that stuff comes in huge sheets and if you contacted a roofing company they should have some extras or left overs from jobs.

but is it safe for water for notl eaching out anything.

i was thinking of doing a 4x4x2 sump this would go along with the 100 gallon ref and 50 gallon grow out tank if things work out.

The epoxy paint method works. I know that. David Grigor had a 300+ gallon tank and then I got it from him and ran it. I believe it has been like 4 years now that I know about it because last I heard it was still up and running at Forest Lake High School in the science department.
I refurbished the top to add epoxy paint around a supporting bracket and that was about 3 years ago now I think.
Though the paint is kind of expensive along with the glue for the seems. I think it would only pay on fairly large tanks.
There are local places for the 2 part epoxy paint and glue though.

This is what I did for my pond and it works great, I know you can buy it at menards if you can't find any from a job site leftover.

How about those plastic buckets they use at the RF cafe?

Thats 47"x42"x29"

why not just get one of the big rubbermaid livestock trough things from Fleet farm, etc. They are crazy rugged and will surely last longer than anything you could DIY.

There is a Tractor Supply Company store at the exit of Concord and Hwy 52 in Inver Grove Heights. I drive past it every day and I always see several, very large sized stock tanks in their outdoor area. I imagine a place like this would have every size available you could ever need. Of course you might spend a little more $$$ up front for a plastic holding tank like this, but it would probably outlast your pond :biggthumpup:

I'd probably just to the livestock tubs and be done with it. Sure it's doable but not really worth the effort IMO. The epoxy paint has to cure in weather above 50 degrees. It's much too smelly to do in the house and in MN its well into spring/summer before the nightly lows are above 50. It has to stay above 50 for 48-72 hours.

Never worked with pond liner but I'd be afraid that rocks could puncture.

if you use the Rubber pond liner (same as roofing liner) its pretty rugged.. but if you use the PVC liner that you can get at like home depot that is not gonna be as strong.
