Starting in earnest on my Discus tank project now.
This is the sump I have designed from lessons learned in recent
60 gallon project.
4 consecutive chambers of mechanical filtration.
10+gal. of bio-media storage area.
extreme low agitation design to keep Co2 from off gassing.
Sealed top
Will incorporate other external features as well.
Watch for updates and build pics.
Get a better animation up soon too.
24" x 24" x 18" / 40+gallons
