450 Gallon Peninsula Display

Pete,

Thanksââ"šÂ¬Ã‚¦Currently I am only running three 250 watt metal halides with XM 15,000 mogul bulbs. I am looking into upgrading to either a Giesemann or a Sfiligo fixture but I havenââ"šÂ¬Ã¢"žÂ¢t pulled the trigger yet.
 
Updated photos from this weekend.

Your lighting looks great, you aren't happy with its output?

Sorry, I never saw your reply. I hate it when I don’t get notified when I get a new post.

I am not pleased with my current fixture for several reasons:
1. My tank is 4 feet wide and this fixture doesn’t handle the width too well.
2. Prefer T5 over compact fluorescent.
3. Overall physical appearance is not very pleasing. I would like one that is much more compact and stylish since this will be a hanging fixture.
 
few LA3 reflectors will give you all the spread you need. my tank is 96"Lx48"Wx30"H have 3 LA3 with MH 400w and the spread is unbelievable. i have also added 3 reef optix v for the front and 8 36" uri super atinic. hope this helps
 
i still love the deep sand bed man. the returns coming out of it are crazy.

as for our combine hobbies, who really needs to eat anyway?

I have read good things about them but I do not like their physical appearance. If I would go with them I would either need to enclose my top or create a hood. I doubt I will find a fixture that can match their spread but I am still researching.

What wattage are you using in the 3 reef optix v?

Von_Rahvin, I love a deep sand bed too but I do hate the way sand gets everywhere. I always thought that the sand would settle a little more then it actually does. I constantly have small sand storms.
 
cbui2, I love your lighting. Those reflectors are huge; no wonder you get great coverage. How big is your system? Do you have a thread going on your tank?
 
Two weeks ago I had a major sand storm. To bad the meteorologist couldn’t predict this one because it would have solved some headaches. I had a Tunze 6100 connected to a WavySea unit for additional water movement. I never liked the piece of junk WavySea + Tunze Connector but I didn’t have any other options to connect it to the Tunze so I just tried to keep an eye on it. Well my worst fear came to pass when my Tunze was able to overpower the weak screw and it pointed straight down into my sand bed. Over 3,000 gph was directed at my sand bed. Needless to say it was a mess. I couldn’t even see my rock past all the sand. I also noticed a spike in my nitrate after this sand storm.
 
cbui2, I would never consider it a hijack. The whole purpose of any thread is to communicate ideas. I am not sure what you are asking about my eurobrace. If you are asking for dimensions I will get that information when I get home tonight?

Thanks for the link on your thread. I looked at your thread a while back and I guess I lost track of it since the page count is much higher than I remember. I will need to catch up on your progress.

We use just 2 LAIIIs running 400W Ushios on IC ballasts over our 78" X 48" X 24" tank. Gives us plenty of spread and lighting :). Sanjay uses 3 LAIIIs running 400w Geisman Coral SEs on IC ballasts over his 84" X 48" X 30" and he reports more than enough PAR to grow corals just about anywhere in his tank.

We went with 2 so that we woud have more light fall off on the sides to give our lower light corals a place to grow :). It also adds nicely to the overall look of our tank.. but I am not sure how it would look or work out for your peninsula tank.

BTW, you tank looks great :D

HTH :)
 
MCrist, great looking tank! One question for you. How come you didn't put the returns for your closed loop closer to the center of your tank and have them hidden in the rockwork?
 
i have similar CL, 4 at the bottom back and 4 front bottom on 2 OM 4-way. you can always add more loc segments to get them closer to the center.
 
Sparkss, My main concern with LAIIIs is not their spread but their appearance since my tank has an open top. I do not want to create a hood or enclose the top. I like the openness my tank has want to keep that style.

It seems like a lot of you are using 400w SE bulbs in your setup. Do you feel that much light is needed? I was only planning on staying with 250w DE bulbs.
 
ramullinax, I originally had my returns under the rock but I didn’t like how much the rockwork blocked the flow. I couldn’t adjust the returns without moving the rock. I had a lot of flow issues and was battling slime algae on the sand. The sand looked like hell so I decided that seeing the returns was better than having all the issues with the sand. As soon as I made the change my sand turned white and no more slime algae.
