Well I tore my Oceanic 50 gallon (30 by 18 by 21, basically a short 75) down the other day with hopes of doing something interesting and different to it. I'm a member on MAAST, a south texas aquarium forum and one of the main posters set up a Cuttle tank so that got me to thinking. He recommended this site so here I am looking for some feedback. I'm completely starting over with this tank. I was using a HOB but I ordered a bit and will drill it this weekend and put a Calfo on it (btw it will have two holes for bulkheads that accomodate 1.5 inch pvc if you anyone was wondering). I have a T5 ballast that I ordered a while back but don't have reflectors yet or the lights. I also have a Koralia 2 and 3. I was using a rubbermaid container as a sump but I got a 20H to start over with, just need to baffle it. No skimmer yet. Oh and for return pumps I have choices, a rio 1400 or 2500 or an ehiem 1262. Or what about an octo tank. This is the third time this tank will go up but they were kind of boring, I really want a nice conversation starter, give me feed back please.
