Sump info

Hello,



I am in the process of getting some acrylic sheets ordered and have cut for a sump I am building but need to know what the size of the baffles I would need to order. I am planning on putting a 36 x 15 x 15 sump under my 90 gallon aquarium. Since I am having the sheets cut I would like to have the baffles cut at the same time. I am planning on having a refugium which I forgot to mention.



Thanks,
