not happy with sump

[martym]

It is a 135g sump. I'm not using baffles because of the length, i figured most things would settle before the return. I want to change that, and add baffles, to help the skimmer, i think it should be doing more than it is. First i will need to remove and store the water for about 24hrs while the silicon dries. Is this going to cause any problems with the main tank? It is a 80g. I want to add a refugium to the sump to get rid of the little 10g that I'm using now. It overflowed the other day which is what started me thinking about the sump change. Do you think it is worth the effort? Any suggestions? Thanks
