I have a 270 gallon tank (6×3×2 l×h×w).
What would be your ultimate sump design for this size of filter.
My thought is to make a moving bed filter with a 1x2x3 area for custom filter socks and a 6"x2x3 return section, sump sections will be divided by matala mat. This will be a overhead style sump because it is 1 foot taller then the pool it will be filtering.

For overhead filtration I like fractionating bio-towers.
I used a scaled down plan from koiphen.com called Phoam Phractionation.
Using a normal pond sponge unit in the tank or pond, pumping a strong flow over a thick pipe with lava rock for bio, as water cascades over the rock, the agitation separates the undesirable parts into foam which fall into a bucket (or the ground).
Maintenance is hosing out the sponge prefilter, and occasionally hosing out the lava rock filled tube if it gets gunked up (outside leaves and debris were common


The above, a pool for Tilapines (Coptodon zillii), which was moved inside in winter.

I use the same on a koi pond (@500 gallons) in the video below.

When inside, they are a little less apt to get clogged with debris.

is this the version that doesn't need an air pump to work?
