^^^^^
This too

heres a basic 3 section sump, (3rd post)

left to right- refugium/skimmer - return

the baffles on the first chamber you could get away with just one versus 2 as the bubble trap before the return would take care of it.

Thanks for the great advice everyone

I have just realized that making 20L as sump would be very very messy. Because, initially, I thought that I can just half fill the new tank, transfer everything over there, make the sump, connect the sump and turn it on. But its going to be very risky to test the system with fishes in (and might be expensive in case I have to refill the whole tank with saltwater). So I guess I will LF sumps/ugly tanks.

Thanks for the input on ATO too. I guess I will use those round blue water jugs; will be easier to refill too.

And I will definitely increase the skimmer section (maybe 8"? because I found out that really big skimmers are like 10") and the return section. Just one question; the level due evaporation is going to change at the return section right?

Oh Oh! And how much are the baffles gonna cost me? I have no idea about those :P

yes most good skimmers are around 8"x8" foot print, for a small system, I'm not sure what your going with or your system size, but its always good to have a larger skimmer section then needed, i made the mistake of having too small of one and wanted a bigger skimmer but couldnt.

as for evaporation, if you install an ATO you wont have this problem, it will only fluctuate about an inch or so. thus keeping salinity pretty stable.

depending on who you talk to for baffles you may be able to get them pretty cheap, I know my sump cost about $30 or so to build with 3 baffles, Denny may have some garbage glass kicking around concept might be worth a phone call.

My system is going to be a 70 gallon (40"x20"x20"; not the typical size :P). So maybe I should keep a 10" area (10"x12") for the skimmer? That's gonna be bulletproof right?

Yap ATO will be there. So the floatswitch and freshwater topoff should go to the return section right?

Yap I will talk with Denny when I pick up the tank.

ya float goes in the return, I put the hose from my ATO in the inlet though so it mixes it bit before getting to the display.

that should be a good size return, I know the skimz sk181 skimmer is about 8"x8" and rated at I think 180g? (dont quote me on that) but the way you stock you'll want a heavy duty skimmer

Oh man I was afraid someone's gonna catch me to that

Thanks Ken for the inputs

Oh two more questions: how high should I maintain the inlet water level? And should the inlet pipe be above or submerged into the water?

can do alot with little room, doesnt leave a whole lot of room for water to come back down in a power failure.
