I'm not very educated as far as the electronics go with lighting. I have this fixture: http://www.hamiltontechnology.com/item/4-DLX-2MH-&-48-FLUORESCENT-110W-1700
I bought it secondhand with 250w bulbs...I bought two new 14K Ushios and put them to work about 4 months ago. It's on my 75g (specs in my sig) and I just feel like it's too much light. All of my zoas/palys retract to the rock with almost no extension. Also, I have to be SO careful with new frags as not too bleach them.
I was wondering if I can use 175w bulbs, and if so, what temp would you suggest?
I've also considered switching to Radium 20K bulbs as this would help a bit, plus better color, but less growth...
Thanks so much!!!
