I do; some small acro. frags. I'm converting slowly and I'm getting rid of my bubbles, gionoporas, and even my torch, hammers and frogspawn. Those guys are BIG and I do mean BIG; and they take up too much space.

Why?

I agree that the thinking of watts/gallon is pretty much history. I have no experience with T5 lites, so anything I say here can probably be taken with a grain of salt. I have run MH over my systems for close to 6-7 years.

Art, how is the acclimation to the T5 lites going? If I am not mistaken, your lites are about 2-3 weeks old now, right?

It's normal again. I'm back to running a 10 hour photosession. It's not so much my zoas but rather my capnella, colts and LPS's. Last year I changed bulbs on my PC lights and my colt started melting! Literally. It wasn't until a friend told me to cut the photosession in half and slowly increase it over a week or two.

That's alright. Colts aren't all that great anyway. I don't know why but I'm starting to not like a lot of the softies (w/ exception of zoas) and some of the LPS's. They take up too much space when they expand. Doesn't matter though, I'm changing over to SPS's.

Have you gotten your electric bill yet to see how much you saved?

Re: How high sould my lights be off the water?

Well, you said they were cheaper to run, I was just wondering how much you were saving per bill. I have a 300 gallon tank that I plan on being an sps tank, I may want to change my 4-400w MH to T5, any info you would have would be a boost.
I guess I will have to give Mike a jingle, he at least has documented info.

They are. I haven't seen my electric bill yet however it's not the only thing that is improving my electric bill. I do have a smaller skimmer and one less water pump. The skimmer only runs for about 10 hours a day. I was a little surprised at how much quieter my system ran. The loudest thing I have is the water pump and even that is buffered by my wood stand.

I like the T-5's b/c it doesn't take forever to warm/start up like MHs. But, all these small modifications including a new LCD television to replace my old CRT is also what's helping my electric bill.

I have some pictures...I'll load them up real soon.
