Hiya folks, I have an empty 180 gal tank that I plan on either doing a mixed reef or SPS tank(Thanks again Fritz and Loismustdie!) But I just picked up a 55 gal former sump for 30 bucks that I had intended on using for a sump BUT i also was just offered a drilled 90gal for 50 bucks. So should I get the 90 and store it until Im ready for another project and use the 55 for a sump or should I use the 90 for a sump with the drilled holes to be used for remote fuge or reactors of some sort. What should I do with the 90 basically is what Im asking. I have my hands full with the 180 right now but 50 is too good of a deal to turn down. Been a week of bargains!
