What changed the look of my lights?

[jaybfresh]

After swapping tanks today, my Halides have a totally different look (3x250w phoenix). In the old tank, the light was dim and very blue. The new tank has bright, crisp, white light. I'm very much pleased with the change, but wondering what caused it:

1) Open rockwork vs crowded rockwork
2) Clear back vs painted black back
3) Starphire vs regular glass

same size tank ? maybe you bumped them causing some sort of light shift ? is the water clean and not causing the tank to white up?

 

[jaybfresh]

Same size tank and reused 70% of the old water. I'm pretty certain the difference comes from having a clear back vs painted back.

But man, they dont even look like the same bulbs anymore

i was going to say power surge....just thinking about christmas lights when they are about to go get very bright.....

2) Clear back vs painted black back

what color is the wall behind the tank? i think this is why your tank looks brighter...

fresh water?

Does a tank good.

when you bump a ballast, the light will brighten up a few days before they burn out. I hope you were graceful and I hope I'm wrong

 

[superkat]

i hope you are wrong, too...but that's what i was thinking...

 

[iamwrasseman]

could be painted vs. nonpainted ..........me no not . i can get the par meter out and check .

Ballasts were mounted on the wall the whole time so they should be safe

had a busy sat. huh Jay?

I often switch backgrounnds from blue to black and sometimes no background-no real change w/ my t5's-

maybe the open rock work and background combined did it.

White wall reflects the light and the black coraline covered backwall soaks it up and tends to throw a yellow tinge to it because of the color of your back wall before.


Congrats-just checked out the pix-nice upgrade-staphire can't hurt either

new or clean, bright white sand, and the clear back glass lets light reflect of the white wall
