Adding baffles to an existing sump

[Jason McK]

After seeing Jacks super silent system (SSS) It really got me to thinking. As it stands right now I really don't think my Red Sea Berlin skimmer is doing any skimming. In order to fit my CA reactor in my stand I have moved my hang on skimmer into the sump. But with evap occurring through out the day the effectiveness of the skimmer is reduced.

My goal is to add two baffles to my sump in order to create a chamber that is not effected by evaporation, Then get a bullet style skimmer.
The problem is, my sump can not be removed from the stand with out removing the tank. That really isn't an option. But it should be hard to get a couple of pieces of acrylic and glue them in place with the sump in the Stand???? or is it.
Also I would have to run my system sump and skimmer less during the process. How long would you think the system could remain healthy with out the added benefit of skimmer, and the aeration of a sump/skimmer?
Any tips or suggestions would be great. Also if anyone know a local retailer that could help with the purchase of Acrylic and adhesive that would be wonderful.

Thanks
