The Hydras are actually quite amazing, I've never seen better growth or coloration out of my corals. The Abro is still colored up and everything pops. The down side is the coverage, these things cover exactly what they claim on the sand bed, but the corals above get shafted.

Make sure you keep that glass on there before staring at it... From what I've read it blocks out some pretty harmful stuff *halide noob talking here*.

Oh yeah the glass was on. Just attracted to bright shiny objects

oh yes, the glass on an HQI DE is a must! They are not UV shielded like Single Ended mogals are. You'll burn everything in its path without the UV glass!

Or pop popcorn

had the same problem as well great coverage down low but about 16" up i lose all spead and par, my coraline was growing up the glass and stopping about 16" all around....clear sign somethings off with the spread:)

:pop2:

wow it all makes so much sense now. there has been alot of things going on with my corals that i couldnt explain or figure out.

Are these units expensive, And who would sell them?:biggrin:

What unit are you wanting. Halide or t5 hybrid?

What's happening
