24" depth, who runs t5, who runs MH? - Page 3

Trying to make a blanket recommendation for the light requirements of all SPS corals is pretty silly. Would a milli and a pavona really react the same to a given light level?

T5 lamps have heavy blue output for a reason, some or maybe most the photopigments in corals respond to light in these wavelengths. Using a PAR meter designed for horticulture may not be the best tool to measure this but it's the best tool we have. However referring to this artifact of PAR measurements as "misreported" completely overlooks the basic requirements of these animals.

great stuff everyone.
That thread on rc was great, some beautiful tanks there that are obviously quite deep and t5 based.

I'm really glad to see the different opinions, I left this thread yesterday afternoon thinking that I must have been daft to consider switching to t5 but now I think I just need to try it for myself and see what the results are.

Whoops. My mistake. I thought this thread was the one where we make blanket bull$hit erroneous statements about lighting and then other members demonstrate poor critical thinking and regurgitate them while they make absolutely asinine comparisons between different lighting modalities.

Come on guys! Look at my signature and see what kind of lighting I have and what kind of system I run. Use your heads! Look at this thread and see what I have said about T5 lighting in the very recent past: http://canreef.com/vbulletin/showthr...t=51194&page=2

Then go read this thread where some serious BS was spewed and several members gobbled it up and regurgitated it without putting on their "thinking caps" http://canreef.com/vbulletin/showthr...t=51164&page=3

Time and again this stupid comparison is made and people puff up their chests about the superiority of MH lighting all the while completely ignoring the multitude of successful large T5 lit SPS tanks. Many of these large T5 lit SPS tanks are at least 24" deep - so there's your evidence. This BB is, unfortunately, sliding down a slippery slope of pouring out some really bad information of late. I also read posts where members denigrate other sites like RC for various reasons. People need to ensure they get a wider range of views on a topic from other sources before they develop such staunch opinions. There are thousands of SPS dedicated tanks running T5s quite successfully, and several of those are at or around 24" - go look it up somewhere else before your impressionable fledgling hobbyist minds are filled full of BS on this BB.

A few of you need to spend a few min in my place when 12 80w bulbs fire up. I'm hoping t prove a few people wrong but like Canadian said thousands have otherwise I'd never have gone t5.

There are so many variables. Like it was said you needtocompare very specific setups.

mods, you can close this thread, I have all the links and opinions I could ask for now to form an educated decision.

thanks very much for all the the strong opinions guys, all very helpful and definitely shows how much of a debate this issue is in this hobby.

I think I am just going to wait till I find a mid to higher end 6-8 bulb t5 fixture and try it out for myself....

My 250x phoenix don't leave much to be desired so no rush, but I'm looking forward to documenting my experiences when I do make the switch.

No way dont close it this is a great debate thread. Leave it open a lot of information to be had, once it starts getting out of hand then lock it down.

Ya, there is no reason to close this, even if the T5 people are wrong...you NEED MH

banditpowdercoat · #30 04-23-2009, 04:04 PM

You know, threads like this make me change my mind more than Michael Jackson changes plastic surgeons.......Ohh, that was a bad one HAHAHA

But really, I just bought a used MH for my tank, waiting on bulbs to come in, to replace my T5. But now, I'm thinking of just keeping the T5, adding a fan on the ends. the tank is like 18" water depth. I'm gona try the MH, but thing they will be reserved for the new, Taller tank I'm gettin.

But anyways, I love reading the reasons each have for liking thier choice of light. No one light is PERFECT. Each person want's, has different needs. It is nice to see that BOTH will work fine. Just depends on how picky a reefer is HEHEHE.
