Thanks everyone. I think if I'm gonna be spending bookoo bucks on my tank for their residents then I think to "save" me headache and possible their lives, I should put some sort of one together before I get any livestock. I still need to get other stuff too but that will come as I find I need it like this.
I'm thinking I'm going to buy a cabinet of some sort to put perpendicular to my tank along the wall. I'll need some sort of overflow box/return box. I'm also thinking I need to shift my tank 4 more inches or so to make room for other cabinet and be able to opening doors (yikes 80lbs of sand and 25lbs of rock to take back out) Would probably be better to do that before I put the 100lbs rock I'm supposed to get this week (LOL).
Any ideas on a size/kind that would work well? I believe I need big enough to hold water from main tank for emergency or something but I don't know how much it needs to hold, preferrably before it hits my floor.
I think I need to buy prebuilt as I'm not good at diy.
