Hello All,
My 12g Nano Cube is in a room that is normally <70 degrees, but can hit the very high 90s for long periods during those summer dead-air spells here in the East Bay. I have all the components to incorporate a JBJ Artica 1/10 hp chiller including a 300gph external Iwaki MD-15RLT pump, sch 80 bulkheads, diamond tip hole cutter, etc. (all 1/2" i.d.). I am balancing flow for the chiller (stated at 240gph) with maybe 3' of head with a desire not to blast the tank with a continous torrent, although I realize that's a lot of flow for 12g. Having spent all this money already, I went ahead and purchased a barebones Nano Cube to drill dry rather than risking a screwup drilling wet. Besides, I guess I can just go ahead and set up the older undrilled tank on an open basis in the basement with metal halides where temperature is not an issue. Space ism though, or I'd go larger. Blah blah.
My question is where to place the Out/In holes in the back of the tank walls? I was thinking Out in the middle compartment and In in the right compartment (facing from the front). If I did that, it seems the In in the right compartment would overwhelm my 160gph internal pump unless I bypass it and run it straight from the glass bulkhead through the partition wall and into the main tank. Also, assuming I'm on the right track, I was thinking of placing the Out hole at a height that, with 90degree elbow turned up and strainer, would put the inlet a few inches below the normal water line.
Another thought that doesn't seem right is to put both Out and In in the middle compartment so as to balance flow, but I'm concerned that would create a recycling of freshly cooled water that will make for other issues?
Anyone have any thoughts on all this?
Thanks,
Newby Lynn
