Are you switching to T5

Well, yeah. Definitely an apples to oranges thing going on. Like comparing a high quality MH bulb with an $8 ebay special.

Are these HO or not

I wish I could take close up pics to show the growth & colours in my corals. However Mike has been over and can vouch for the difference, as it was 2 months since he last seen my tank.

Whats a halide? So many of them, just saying I would use halides instead is a broad statement. I ran 175w 14K,s over another aquarium and they cant even compare to my T-5,s. Not even my 250 14k over my 45g cube did as well as these. Darned if I know.

When we say this though, what other factors come into play. Who knows. Why are some having success and some not? Same as every other aspect of our hobby I guess. Like BB or DSB.

I played with T-5,s before but always went back to halides and even participated in a thread where I agreed the halides were better for the corals. However I have never given the 4ft. HO,s a fighting chance, which is what I,m doing now.

Why a reference to compacts? Maybe these are no comparison. Why would sps corals not grow under enough light of any kind? Its like the old saying they dont do well under vho lights, yet a few years ago, a friends 120, lit with 6- 4ft. vho bulbs would make you cry if you seen the colours in his sps. Now thats 6- 110w bulbs compared with 4 or 6 54w bulbs. Again, I dont have an answer. He now has a larger tank and runs 400w halides. He would use 6ft. vho bulbs if he switched but he would never go back to T-5 bulbs, that he ran on it before. Mind you he only ran 4 sets of 3 fts. So 8-3ft. HO bulbs. He to thought they were great at the start but in the end, basically threw them away.

I will be interested to see how Mike,s does under the 8 bulb fixture in comparison. Now how the heck can that not be enough light in a 24in. deep tank? Wholey mackeral.

I know mine are doing well now and only time will tell what success they will be. I have 4 clams and they are doing great, except for my fight with pinched mantle. I do know, that I watch my corals closely for change or colour loss. At least I have not had any that bleached like under my halides.

All that being said, success will be when or if my tank & sps ever look like Jason,s or others running their halides. Hard to argue against that.

Well that's what I had that browned out all my SPS frags.


I thought they were HO but didn't want to go off on T5 without the facts

But there are TONS of other people who exclusively use HO T5 bulbs and have brilliant SPS in their tanks.
