I think a 20g would be fine for a sump... basically all you are doing is skimming the water, and hiding equipment. As long as you have enough volume that evaporation shouldn't become an issue, (I highly doubt you'll evaporate 10 gallons a day), then I think you would be fine.<a href=showthread.php?s=&postid=12827882#post12827882 target=_blank>Originally posted</a> by chatyak
