My friend has a 60g reef and just added a 20g tank as a sump. He's undecided how to utilize the extra space. I thought maybe a dsb with macro would be good, but I've been reading that that a 20g may be too small to keep a healthy dsb. Any suggestions whether a dsb will survive in a 20g. We'll probaly chamber off a small section to use as the return pool which will take away from the area we are allowed to use. But I think he should go with the macro a some live rock for sure, let me know what you guys and gals think.
