The water inlet square area should have a taller edge than the adjacent area to the crytic section and the skimmer bay, so that water will not spill over the edge. May not be a concern. Is there any plan to add light to the cryptic area?
Getting closer to building the sump now, the following is a scale drawing of what it will look like.
Size (in inches) is 18L, 24W, 12H
Comments are welcome, as i am about to build this thing.
Cheers
Bubble trap is an UOU.
To ensure water flows from bottom to top of cryptic area i have put an initial 'under' baffle to force the water down, then back up to the exit again.
I have a tremendous amount of space in the right hand compartment, which will house an OR3500 and a heater. If anyone has any constructive comments as to what i can use this space for, i would be grateful
dont have a problem with bubbles, and the flow is like 1100 gal an hour ( mag 2400 pump )
if thats going to be just a sump its good but you will find there is NEVER enought room in your sump for silly things like heaters/uv ( if you go that way ) auto top up stuff..... the list goes on, probes ( if you go that way ) take up space
your cryptic zone i think is simular toa benthic zone ? no ?
