Metal Halide for Acans

[Psionicdragon]

Which would be the best for Acan and micro growth: a 20k XM or 14k Hamilton or a 10k bulb?

Also, do they like a lot of flow, medium flow, or low flow?

Had all three, stuck with the 14k Hamilton & 2 96w Actinic

Best color & growth, JMO

I have always been told that the best coral growth comes form 6.5K bulbs. As you move up the spectrum the coral coloration gets better and the growth slows down. Now I am running 10K Reeflux bubls and I like the coloration better than 20K XMs so maybe there is an answer for you. Better color and higher growth.

10k produces far too much yellow for my taste

not the coralvue reefluxes

Have you seen these bulbs. I would not use 10ks before this. You are correct they were all too yellow. Not these bulbs. You should see them.

i run the coralvue reflux bulbs, best bulb on the market IMO. No yellow at all, just crisp white.

I also run the 10K coralvue Reeflux on my tank. But I also run 2 coralvue 20K bulbs on either side of the 10K. I like the mix.

Here's a pic. I keep most of my Acans on the far left side. You can see it looks a little bluer than the middle since I have the 20K's on the ends.

The tank is only 4 foot long and has the three halides squeezed together. The 20K's are 250watt overdriven by a PFO HQI ballast. The 10K Reeflux in a 400 watt bulb run on a Blueline E-ballast.

I always thought that was only for SPS. So this is also true for LPS?
