Which one should I get?

[skylord]

To many unknownes...sump or not? Type of pumps...will the tank be in a basement? But....I would still choose the 2 pendants over the Corolife. The reason....you can always shut one of the pendants off on those days where heat is an issue. On a 36" tank I would probably try one 250 pendant with a couple of HO T5's. Less heat and good light combo IMO.

Skip those. Give me a call at the store before Wed

I disagree about the need for a chiller with properly place fans and a proper auto-top off system heat should not be a major concern. Not enough to make me not get them anyways. i think there are many steps that can be taken to reduce heat from MH without the need for a chiller.

LMAO. Thats the same thing I thought. My house is air conditioned and I still had problems. When the lights came on, the tank temp would climb at about one degree A minute. It doesn't matter how many fans you have, It can't compete with that.

Personally, I wouldn't spend money on any Coralife product. Cheap crap. It breaks - A LOT. So of those two you listed, I would go with the pendants.

I have a 36" tank that I am figuring a lighting setup for as well. What I have decided on (unless someone changes my mind with info I haven't found yet...lol) is a single 400w XM 10K bulb (~$90) run by a PFO HQI ballast (~$215). This combination is one of the highest PAR ratings you can get. I'm going to put that bulb into a Lumenarc III reflector (~$160). The reflector is a pendant that is a huge 19x19", and fugly as hell, BUT it is better at evenly spreading the light across a larger area without losing as much PAR in the spread than any other reflector (that I've found).

I have researched my information from Sanjay's Reef Lighting: http://www.reeflightinginfo.arvixe.com/ As well, I've been doing a lot of searches on different forums, and come to the conclusion that this lighting combination should spread across the 36" length sufficiently. However, if you plan to keep a 100% SPS tank, then I doubt you could get away with one light. I have LPS that I can place on each side of the tank where the light isn't as strong, but will be quite sufficient for LPS.

What are your coral plans?

I don't have a sump nor a chiller nor an auto top off unit (wish I had one though). Basically this tank is going to have to be ghetto. Corals that for sure will go in once params are stable and I have a light are: toadstool, frogspawn, hammer, rics, gsp, m. digitata, mushrooms and candy cane; I realise those are mostly lower light needing, but I would like to be able to diversify.

I would still like the option to put in a clam at some point if possible. I am really having trouble deciding what to get. Help very much appreciated especially if it is a specific light you recommend.

Side note to Albert: Could not get to Calgary and for me it is not worth the drive if I don't know what I will be looking at (vehicle is a MAJOR gas guzzler); so if you have any fixtures that would work show me some catologue-like pics with prices or something so I have an idea before I go.

Can you PM me your phone number? I talk faster and more elaborately than I type :P

Considering heat will bea serious issue for you I would recommend you go with T5s. Your tank is a bit deep, but as long as you keep good water quality and specifically clarity (run carbon) you should be ok. All those corals would be quite happy undr T5 lighting, and if you get a clam you can always make a little shelf out of liverock that you can then put a mini sandbed on, and put the clam on that. I have seen that work well. Also some clams like to be right on the rocks anyway.

So I'd recommend the Sunlight Supply Tek T5 4-bulb unit. I think the 6 bulb unit would be too wide for your tank. It runs WAAAY cooler than Metal Halides. You need to replace bulbs a bit more often - about every 8 months. With the 4 bulbs, I'd try a combination of two URI (UVL) AquaSun, one Giesemann AquaBlue+, and one Giesemann Pure Actinic. Should give you a nice color.
