So I am building a 1000 gallon plywood pond. It will be filtered by a swirl filter, then by aquaponics. It's going to be 8 feet long, 4 feet long, and 4 feet high. What cichlids do you recommend?
I'm really curious xlegitxrangerx...
You said it's a 1000 gallon plywood build pond with dimensions of 8' × 4' × 4' and while I agree that those measurements are quite respectable, I have noticed in the picture you posted, that you have overlapped the plywood sheets as anyone would do likewise for the basics of good solid joints (short of the reinforcements to be added later I presume).
In the photo it appears you have used 1" plywood and that is a good start.
My question is simple and pardon me please if you presume it to be too straightforward, but I feel I must ask.
Considering the overlap at the corner verticals and considering the height difference of the left and right panels to the farthest panel shown...
By my calculations, presuming you used standard size ply sheets (and your stated measurements indicate nothing else) -
I calculate that your:
right panel is resting on the bottom panel.
near side panel is resting on the floor.
far side panel is also resting on the floor.
bottom panel is on the floor between the 2 end panels.
left and right panels are resting on the bottom panel.
This arrangement does account for what we see & provides internal dimensions of 96"L × 47"H × 46"W.
96 × 47 × 46 = 20,552 cubic inches.
20,552 ÷ 231 = 898 gallons if filled to spilling over.
If filled to within 6" of the top, you're looking at 784 gallons.
I'm presuming your filtration will acount for the remaining 216 gallons and that's fine.
But please... I have no idea what a swirl filter is and I'm new to this stuff.
See for yourself. I just joined this wonderful and helpful group of people in April this year and your plan seems to be well within my budget. I rather like it.
I'm hoping you continue to post your progress for all our benefit.
