Please Critique My Sump Design

Thanks !

The Skimmer is a Berlin AirLift 90 with a Dolphin 2 Star AirPump. The middle
area will be used for refugium. Thanks Again for your input!

Thanks !

I'm not sure how you hope to work your carbon resevoir. There is a good likely
hood that the water will pour right over the carbon, rather than flow through
it, but you didn't include any specific details to that zone.

The final baffle before the pump could be as tall as the inner one (12") which
gives you a little more water in the return zone. Which allows for more time &
evaporation to occur. One person's sump currently is so small that she has to
top off 3 times a day. Might as well install an auto top-off device than put up
with that!

Other than that, I think it should work out quite nicely.

thats actually a good way to run carbon on a reef, assuming that was his intent. it
removes some of the negatives given to carbon in a reef setting, another thing is to take
the square shaped carbon holder turn it into a V and put slits on the side away from the
skimmer allowing a good portion of water to flow over the carbon and a good portion to
flow thru the carbon. just a different view, either way probibly works good

I have a 10g setup that way, the auto topoff keeps it up, but w/o it there isnt much room
between full and empty bout .5gal

Other than that, I think it should work out quite nicely.

me agrees

From what I can see ...
1. Your water level for the skimmer section seems too high for an insump
skimmer. The water back pressure will cause skimmer problems.
2. There is no need to have a middle inlet from the tank. This will in fact
make the skimmer less efficent as not all of your water is passing thru the
skimmer hence chances of a lot of un-skimmed water going back into the
system
3. If the ball valves are for flow volume control, use gate valves instead.
Ball values are meant for on-off operations and not volume control.

HTH.
