Sump/fuge for a large cube

Ruth · #1 02-07-2006, 03:31 PM

Overflow is 12" X 18" and has 5 holes (I think - it's still all wrapped up). 2" drain and 4 X 3/4" returns.
I don't think I could do the stacking thing with 2 separate tanks as the sump/fuge will be underneath the display and I also want this display to actually be lower than normal because my "plan" is to make it top down viewable for clams.
So far I have most of the equipment I will need - calcium reactor, tunzes, protein skimmer, return pump.
I am still a little undecided on how I want my lights to work. Initially I was going to go with 2 X 250W MH supplimented by VHO actinics for one "side" of the tank and 2 X 400W MH with Luminarc reflectors. I actually have this purchased but am now thinking that I may just want to go with 4 Luminarc 400W penants. I guess my question is how the heck would I suppliment this with some kind of VHO actinic? Could you just go with a fixture with only VHO and sort of run it down the middle?
Help and suggestions most appreciated.

If you stand is low, to get two tanks you will probably have to do as I mentioned. That or use a tank that is shorter than the other, that could save drilling one of the tanks.

If you want MH and VHO on a 4x4 tank, im thinking one giant hanging fixture. You could then put the lights wherever you want in it, including 3 or 4 ft VHOs. This would take some woodworking though.

If woodworking isnt an option, the other option is to buy 2, retail 4ft fixtures with 2xMH+VHO already in them. Then just hang them side by side. It would be like lighting 2, 2x4ft tanks. Hamilton for example, makes these. THey are available at JL aquatics. There are also some pendants with PC actinics built into them as well, but pretty weak and pricey.

I'd be seriously tempted to put some surge tanks on a tank like that. Maybe two surge tanks and an above-the-display refugium and just leave the sump as the sump.

Man I'd love a 4x4 cube. That's not gonna be fun getting it into your place though (I wouldn't even be able to get one like that in my basement at all, I checked .. !! Unless it was maybe built in-place.)

I assume the cube is going to be a walk-around, not up against the wall, so having a fuge above the display might not look so good. Unless you did a secion of drop ceiling to put both the lights and a fuge in, with an access panel on one side....... Wouldn't cost THAT much to get a drywaller to do for you, then you could go with retrofit kits for lighting, save a bit vs. pendants or full fixtures.

Well I already have the 2 luminarc pendants so will be using them and probably buying 2 more and selling the 2 X 250W with VHO fixture. Is there a fixture that just has VHO? I am thinking either 2 or 4 4' VHO and just hang this in between the luminarcs. If I can find someone to build me a fixture that is definately and option.

Ok, what you can do then is keep your 2x250w + VHO fixture, hang that on half the tank. Then get a bare bones fixture, put in your two pendant bulbs, and just add VHO. This way all you are buying is some VHO, and a fixture.

I must be confusing. I already have 2 X Luminarc 111 pendants

with the connections and ballasts. I will be adding another 2 (I think), selling the 250W fixture and wondered how I would incorporate some VHO actinic lighting into this set up.

You currently have 2 pendants of MH, AND a fixture with 2 MH + VHO, is that correct?

If that is the case, buy a bare bones fixture to put the 2 pendants into, and add VHO to it. Then you will have 2 fixtures, each with MH + VHO in them, and that will be perfect coverage for a 4x4

Here is a better link

These are big reflectors - approx. 20" X 20" so I don't think that a barebones fixture box is available - besides which I would have no idea how to put the thing together. I was thinking that I could hang all 4 pendants and then somehow run a VHO fixture down the center.

It always seems to me that Ruth does the coolest stuff.
