40g sump overkill for 40g breeder DT?

With my 36g bow front fallow for a few months and petco having its $1 gallon sale, I figure it's a good time to move everything to a 40g breeder. I bought a 20g long with plans on using that as the sump but thought that bigger might be better. So I'm thinking of getting a second 40g breeder to use as the sump. But would that be overkill? Should I just go ahead and use the 20 long as the sump? I don't really plan on going bigger than 40 any time soon. I will be making my own stand and the design will be a bit tricky but I'm sure I could figure something out so that won't be much of a problem.
 
absolutely! just keep in mind you need a little space around the rim of your sump for possible add ons later. I have a pretty large acrylic sump under my 40 and have multiple reactors hanging on the edge. I barely have the clearance for the door to shut on the stand. Just keep that in mind when you build the stand.
 
I'm running a 40b/40b combo, but my sump is in the basement. To answer your question, no, it isn't overkill. I've read somewhere on RC, someone was using a 75 ( I think) with a 400 gallon tub.
 
I have a 225g sump on my 225g tank.

You should always go as big as space allows as the more volume you have,the more stable you system will be.
 
Alright I'm sold! I'll return the 20L for another 40b. Now to research some sump design plans

Good for you. I think that's a great decision. I have a 125g sump/refugium under my 65g shallow reef and 25g frag tank combo. And a 180g sump/refugium/DSB under a 180g reef and 75g hexagon DT. Bigger is better.
