ok so my tank from up above, the big blue container, yeah i woke up this morning, and the little feet built into it had pushed up into the bottom just enough to make a super tiny crack, yeah well that was just enough to make it leak and have to be replaced. So it actually got replaced to a 20 long, because of the way the filters were hang on the back it had to be a short tank, and the next size was a 40L which was too long for the cabinet its on. anyway my question is with a 20L, i know its possible, but how hard is it and how would i go about plumbing it in with another tank next to it so its all the same system, or would it be easier just to make two different set ups that way i could grow like soft corals in one and sps in the other?
