300 gallon tank, 96*48*15

How's the spread of the light over the tank? Do the lights cover the tank? I'm considering using my 2 400w Iwasaki's combined with 2 400w xm 20k's or 250w DE 20k's.
 
I am very pleased with the light spread. Lights are horizontal. Spread is goo, the extreme sides of the tank, front and back, are probably not bright enough for sps, but zoas have not problem.
 
Well, I'm going to the lumber store to pick up a 3/4" sheet of plywood. The tank has sat on a 3/4" sheet of plywood for 5+ years, but I plan to add a couple holes for a closed loop, so I want to add another sheet to be sure I'm ok.

Well, I bought the board for extra support and bought some lighting. I am going to have pendants made of wood that will hold my 400w Iwasakis and I just bought some 250w ballasts to run xm20k's or radiums. I may also throw in a couple 24" URI VHO Actinics in each pendant. The Iwasaki's and radiums will share the same reflector so they get a good blend of color. I will need to hang them 18 to 24 inches off the water to get the spread, but with 15 to 16 inches of water, I'm not worried about having enough light.

Lighting Configuration

Ok, I need help with the configuration of the new lights in the pendants. The pendants will be made out of wood to fit the reflectors. The question is how to configure a 400w Iwasaki, with a 250 20k, and possibly 2 24ââ"šÂ¬Ã‚ VHO Actinics. They need to cover a 4 by 4 foot area, so the reflector probably needs to be wider, but I donââ"šÂ¬Ã¢"žÂ¢t know that. I have a set of PFO 24ââ"šÂ¬Ã‚ parabolic reflectors, but they donââ"šÂ¬Ã¢"žÂ¢t seem very wide. Also is the question of how to fit the two metal halides into one reflector. In a line at opposite ends facing each other? 3-4 inches apart next to each other? Opposite ends facing each other slightly off set?

Any opinions are appreciated.

PS, I found this in someone's gallery.

Quick update.

Quick update.

Support: I bought the extra Ã"šÃ‚¾Ã¢â"šÂ¬Ã‚ sheet of plywood and cut out the existing holes and placed it under the tank. That puts my support up to 2 Ã"šÃ‚¾Ã¢â"šÂ¬Ã‚ sheets and I plan on putting 2 2*6 cross members in soon.

Lighting: I have 2 400w Iwasakiââ"šÂ¬Ã¢"žÂ¢s, 2 250w XM 20kââ"šÂ¬Ã¢"žÂ¢s and I might put in several VHO strips.

Flow: I have secured an AMP Master 4700 and an AMP Master 3000. Iââ"šÂ¬Ã¢"žÂ¢ll put the 4700 on a closed loop through 4 1ââ"šÂ¬Ã‚ inputs to be split into 8 Ã"šÃ‚¾Ã¢â"šÂ¬Ã‚ loclines. The 3000 Iââ"šÂ¬Ã¢"žÂ¢m going to use for a euro style DIY skimmer and to feed 1 or 2 carlson surges from the sump to the tank.

Home for the Tank: This is the most exciting part. We close on a new house at the end of this month, so Iââ"šÂ¬Ã¢"žÂ¢ll be starting setup soon. Hopefully this tread will get busy with updates then.

Haven't buffed out scratches yet. I just hosed it off really good and dried it off a little with a towel. I did use an acrylic cleaner to get at some of the stubborn junk. For that I used an old cloth diaper. I'm going to contact a local acrylic shop to see what they would do with the scratches.

PS, I used ProGlow. The plastic shop said to use a polishing compound they sell and a car polisher to get out scratches.
 
Thought about luminarcs, but I want the 6500k and 20,000k bulbs to share the same reflector to get a really good blend.
 
mwood:

I just received my Luminarcs last night. You might be able to purchase the reflectors without a cutout for a light socket and then drill your own sockets (one on each side) and fit two lights in, parallel to one another but entering the reflector from opposite sides. However, it would be easier to just put 10k bulbs in a standard Luminarc and supplement VHO actinic, IMHO.

OK, lets get this thread going again! Here is the new house we just moved into. "Let me show you a picture of my deck" blue collar tv. This will be the home of the tank.

Here is a photo of the tank in it's place. I'll be building the room around it once I'm sure of where I want it. Took two large men to get it down here.

Here is a pic of the sump with 300 lbs of cured rock from a local getting out for a while, but he'll be back. This addiction is worse than drugs. :bum:

Next thing is to drill and shim. I'm getting help with the shimming from Dan the man. I'll post more soon.
