bulds that run 20000k do they turn your tank blue NO. So Idk what your deal is or what kinda lights your looking at. I was making a suggestion. This is aquarium advice is it not. This argument is of topic and not needed. If he decides to follow my advice then he does either it works or not. Its a forum that has lot of opinions. I entitle you to yours. Entitle me to mine and shut-up.
Sorry dude. I've never heard of 30,000k bulb but when you google 30,000k you get car head lights only, try it...
But if my lights were to low as you state . There on a dimmer and I have them as low as possible..So turning them up wouldn't be a problem.. And alot of respectable company's use 10,000k leds.. Figured I was bleaching because of too much or light shock either way is too much, not too low.....
If i get to 100% and still having trouble with my water test coming back clean then I will consider low lighting being the issue. But I highly doubt if anything it's too much.
