i remember when i first got my LED system running. it was 50/50 white and blue. looked very bright and very purple. (like 20k+) after a week or 2 i noticed it becoming more 12-14k ish. and then just plain 10k.

that was when i stared at my tank at least once a day.

now iv been busy with work and school and noticed the lighting a lot more intense like i can barely look at it. and the purple tone is back.

have u guys noticed your eyes adjusting back and forth? same with MH.

drugs

OK, seriously, sometimes my Phoenix 14K looks more like 10k if I am seeing the light a lot. But if i come home from work etc, or the room lighting is on it looks more blue. So yes, ou eyes do adjust I believe.

no im clean. drugs are really expensive can barely afford live rock for my tank...

i read somewhere that the eye does adjust to light. after starting at my tank the white background on my computer screen looks ugly pee yellow...

man those it strain the eyes.

it helps to have a comparison i guess, but i have 4 other tanks in the immediate area

The only time I see a difference is if I'm looking at aonther light source with a different color temp for a long time and go to look at something different. I have 6 tanks in my office, so that's not hard to do. Never seen a purple tint in any of the LED rigs I've built.

your just giving your retna a sunburn. Kinda like looking at someone welding. I have a 400w HQI and if I look to long all my other tanks look extremely yellow even the t5 tank.

my tank has a purple tint sometimes when I first see the light on (PAR38), but that goes away as my eyes adjust.

Do I dose with these or apply them directly to the lighting?
