I've decided to get back into the hobby and found a great deal on a 45 gallon jbj rimless. I've always had a sump for my other tanks but was wondering if I could get by with just a HOB skimmer. A friend has a Aquamaxx HOB-1 in really good condition that he could sell me for like $50. Wanted to see if you guys and gals had any thoughts. Thanks!
