Hi guys! I’m fairly new to aquaponics and am trying to set up a system using 275gallon ibcs and 55 gallon barrels.
I’m going to do 100 fish, 50 fish per ibc, have them set on a gravity feed through a 2” pipe to a radial solids drum. From there the solids will go to a mineralization tank. The clean water will go through 1” pipe to 8 ibc beds filled with 7 50L bags of hydroton each. Each individually set up on a bell siphon, which will run back in a 3/4” pvc to a ibc sump underneath the fish tank. From there I will use a sump to split feed it back into the 2 250 gallon tanks.

My problem is figuring out what size pump I will need. I feel like I should use a 800gph pump, as that will circulate the whole system about 2x per hour. But by my math I’m thinking the 55 gallon radial solids filter will have a retention time of 3.75 minutes, which I don’t know if that’s long enough to filter the solids.

Any help or advice to the system would be greatly appreciated!!

For cycling 2x an hour I think you only really have to count the fish tanks versus the whole system so that would bring it up a bit, but I think 3.75 isn't too bad for an RFF/RFS.

If you’re concerned about the time in the radial filter, you could always have 2 in parallel so the retention time would double with the same overall flow.

Hi and welcome to the forum

System design sounds great

You will probably find you wont get enough water through your gravity flow inch pipe to your growbeds , every join , bend ,tap ect will eat into your flow rate

I use 50mm pvc with a size reducer and elbow that is not glued (twist up an down to adjust flow)

Or use Taps if you prefer
