This EcoPlus 290 GPH Submersible Pump is not really large enough to run a low pressure aeroponic system.
It just doesn’t have enough volume even with only 6 heads.
I have tried it and it barely works for that. However it makes a handy little transfer pump.
They come with 2 each 3/4 x 1/2 and 3/4 x 3/4 barb fittings. You can remove the intake cover and screw them in and attach tubing to both the intake and output ports.

Great for draining reservoirs, totes or adding nutrient solution. Even though designed as a submersible you can use it out of water as long as it has liquid passing through it. Actually it’s a great little pump at just under $20 that has a sponge filter to keep gunk out.
