Okay, so no valves needed. Do you run some kind of tubing between the overflow and the sump, or PVC
? I've seen both, any pro's or con's to one over the other? I read that you will have 2-3 gallons drain back if the pump shuts off, with my design there should be about 4.67 gallons of overhead. 27 X 10 X 4 / 231 = 4.67
Should I run the Mag 9.5 or the 7? The standard Lifereef overflow maxes at 600GPH.
The Mag 9.5 pushes 800GPH @ 4', that is 200 more than the Lifereef overflow can handle. Will this cause a problem without something to throttle it back?
The Mag 7 pushes 475GPH @ 4', the Alpha 170 skimmer pulls 1,600lph or 422GPH per my calculations.
Yes, that is the skimmer. It is made by Royal Exclusiv for Vertex, they are the people who build Bubble King skimmers. I have seen three different footprints for that skimmer, one person who own it stated that it would fit in 7.75" X 12.5", but it should fit in my sump either way. I won't put in my baffling until I have the skimmer in hand. I really want to own the best, and these are supposedly built nicer and run quieter than anything else. Very easy to adjust, and the collection cup just lifts off. I have not owned any skimmers yet, but supposedly most have to be screwed off, and that is somewhat difficult in a tight stand, which mine is. Are there any equivalent Reef Octopus cone skimmers to this model? Same specs, etc...
I already have two reef capable LED
light pendents on my tank, which are suppose to be equivalent to a 150W metal halide each. I can't verify this, as I don't own or have access to a PAR meter.
In the end, I may do none of this, and use the money to upgrade to a larger aquarium, I really want a 125-150 gallon tank. I'm just trying to learn, and plan it out right now.
Thanks for your help so far, I really appreciate it!
