1) I want to ge the tanbk out of my truck,but I need to put the 55 in the stand from behind bbefore I do this. I assume if I put it in the middle or to one side I can run both overflows from one sump? Is there a better way.
2)what kinda pumps will I need to get the overflows working properly?
3)When does halide heat become an issue enough to get a chiller? I can;t afford one so this will detirmine which kinda lioghting to get. I was think 2x400w MH and 2x 110 VHO 03's. You htink that will need a chiller if I add some fans etc....?
4)skimmer can run out of the sump right?
1) Place the sump in the stand how ever you wish. If the overflows dont have true unions pickup two from your hardware store. Plumb the overflows down a few inches below the stand top and install the true unions one on either side and then plumb the drain lines into your sump how you want. If you want to plumb them to either side of the sump or if you want to plumb them to the center it dont mater.
What size plumbing does the overflow have? 1"? 1.25" 1.5"? I would get either a pair of Mag 12's or if you want to drill the sump you could use an external pump like a pair of littlegiant 4-MDQX-SC pumps. One pump per return and have a SQWD on each return so you basicly have 4 return outlets that alternate. If you do the mags in a submersible setup then install a true union after the pumps so you can easily detach the pumps from the return plumbing should the pump need service replacement. Also install a ball valve above the true union on the return so you can throttle the pump if need be ( I dont think you will need to) or you can close the return off if you need to detach the pump.
When your water temp is steady above 83F during the day and fans dont cool the water down enough is when a chiller would be needed. For a 180 thats 6' long you need 3 MH
bulbs if you go the MH
route. Honestly I wouldnt do a 180 without MH
's. Instead of going for 400W MH
's go with 250W variety. The 250W MH
's each centered over the three openings above the tank and if you want you could get a pair of 6' VHO
ultra actinics to supplement the MH
's. This will give you ample light for just about any softie and LPS
and you could easily do SPS
in the top half of the tank.
You should place your heaters as well as skimmer in the sump. If you go with a 55 gal
tank you could put two glass dividers in the 55 to partion it out and form a sump/refuge. You could split it up so you had a 10 gal
area on the left where water entered the system. Have a glas partion that was about 3" shorter than the55 is tall that allows water to flow over into the refuge area. Then install a simular glass partion on the right side where you have 5-10 gal
for your return pumps. Then the middle area ~30 gal
is a refuge where you can put sand and macro algae and your heaters. The skimmer can run on the left side where your water enters the sump.
If you lived closer I would loan you my services in helping you set this up.
