Pete,

First, thanks for the quick response. I have read many of your posts, your website, and your work. Before finding MAAST, I thought I would have Melev construct my sumps, but then I found your work. Very nice.

Can you build a calfo in black acrylic? Would two drains in the calfo work well on a 75? Unfortunately, I can't do a calfo on the 55 due to the way a DAS tank is constructed, however, the bottom can be drilled.

What info do you need to construct a sump/refugium? I am assuming the dimensions of the stand, fact I want an external pump to reduce heating the tank (is that true?), and what type of skimmer (actually thinking of going skimmerless)? What else?

Thanks,

Lee
