help me plan my sump

[1337cr3w]

this is my current sump plan after doign a bit of researching and your pms i'm thinking this will work lmk what you think.

the water comes in the right chamber with the skimmer and gets skimmed. it then straight from the skimmers output gets put into the far left chamber with chaeto in it. the brown lines on the right of the chaeto area are a fine plastic mesh... think of it as really really fine eggcrate. which leads the water finally to a or2500 pump that sends it back up to the tank. the chaeto compartment has a 150w halogen above it.

i don't see any major problems in the design but i also have never had a sump before so let me know what you think plz.
