39 gallon sounds nice to. I wouldn't think a gallon of water would make that much difference in size. Yeah I agree that the more water volume you have the better. On that note I may have to wait on adding rock and water this weekend until I can get another 20 gallon long and build it into a sump. Only because I have to take my cabinet apart to add the sump in.
I ordered the clean white dry rock which is arriving today. I'm not going to rush through this build. I want to take my time and get everything right. I don't want to have any regrets down the road.
I will check the prices on the 20 long and maybe pick one up this weekend. I will have to get some glass cut to section off the sump refugium.
