i think better yet you should decide what kind of corals you want to keep and what kind of lighting you want to use, then this will help people offer their opinions on what fixture to buy

One of the things you must consider is that, whith PC lights, the only part that is getting all the light is the part of the tank that has the light over it. While yes you may have 4bulbs, but only 2 are over half and 2 over the other half, while with T5's it goes the length accross the tank. So you'll need more PC just to equal that of the T5's.

You can check http://www.reefgeek.com/product/48_i...ulbs_by_IceCap . it's not badly priced either. You'll be getting more wpg then i have now and less heat.

Ok i would like a torch coral which will probably be the highest required coral I'll have, I think maybe a mushroom or two, some sponges, yellow tonga, orange tree ( or some tree) Coral, red sun coral, and a polyp would be nice.

Ive not researched into coral a ton, meaning im not sure how dense your population can be, if there are rules to go by having a 55 gallon tank. I haven't yet because im still months away if i do things slow and right from having my first coral.. and i dont want to get excited to soon :)

that is excellent. i am very impressed with you attitude on wanting to go slow and do things right, in the long run your going to have an outstanding tank and your hard work will pay off!

sun corals actually do not need light and prefer dark/shady areas. they have to be fed daily by hand.
and as for prior your edit, yes you can have too many watts per gallon. for example 250watt metal halides on a 10 gallon is just going to bleach everything out. with the lights your looking into getting you shouldnt have a problem.

that lamp would be 10 watts per gallon, and pretty much leave me as far as light open to any coral. My problem is the freakin moon lights. ( i may also down the road move up to 75 gallons.. and that can move over also ) back to moon lights.. i dont know how many i would need to get that really nice glowing effect in my 55gallon.

see what i mean by wanting to upgrade, its great that your planning the upgrade now so you can keep that in mind. thats what i did with my 46, i knew i was going bigger so i put 4 t5s on it now and actually they stick out off the tank alittle bit but i knew this would be temporary and smarter then buying a fixture now and then a new one when i upgraded. since mine is a retrofit its not going to be a problem to add an aditional 2 bulbs which i already have the ballast and reflectors for. i honestly do not have moonlights. my sump is open so just enough light "escapes" to make sure the tank isnt in total darkness. ive wanted moonlights so that will prob. be something i include in the next tank, you dont want too much light in a moonlight where it effects your fish's downtime or causes bad algae growth, its really for a really low light soft glow. im going to make up numbers here but 1 watt (x3) LEDS in blue would make decent moon lights in a 55 you can buy LEDS and retrofit these yourself too which is way cheaper then buying a moonlight setup by itself.

Cool

So.. to summerize then.

10watts per gallon is ok and wont kill or bleach any of the coral I mentioned, even if I put them on the live rocks.

MH > T5 > CF

Current USA Outer Orbit Fixture 2x150W HQI & 2X130W Compact Fluorescents, 48 inch 48 current outer orbit

this light could meet all demands of a 55 gallon or 75 gallon set up, with coral, fish, sponges (spong bob) lil toy submarines, really hot sexy 5'10 green eye red hair mermaids, and jaws.

I'm looking for universatility here baby!

10watts per gallon is alittle on the strong side
i think thats a good light fixture and it would work with the 55 and 75 as both are 4 foot tanks.
sponges are filter feeders meaning they feed off of small particles in the water. i would skip the submarines, mermaids and jaws decorations.

I personally wouldn't go with the PC lights, but if you are thats fine.

I only have 3 LED"s over my tank for moonlights and thats a 55g as well. I built mine from scratch and it's really easy to do. It's my first DIY project and it worked out real nice. You can check here

so you two would NOT go with this light.. they say they are PC.. but also that they are MH HQI lights, but the watts on this with my 55 is like 10 watts per gallon.

Just give me your straight up opinoun.. im not going to take your opinoun and rush out and make a decision.. but i will base your experinces on my research and have a much more informed final decision.

I want a light i can move up if needed, and instead of spending 200 now, oh update, 300 later, oh update, 300 again.. i rather just go with freakin 500 bucks now and call it a day.

DIY is not out as an option.. its just this stuff is over my head.


PS. The 5'10 red head mermaid with green eyes was going to be REAL, not a decoration champ.

PSS. They say CF lights, but the diagram as the lights going all the way across, without the gaps that I was told about with CF... this confuses me. are the CF or MH!

Christopher.
