  1. Having had LED's only in the past, I recently added a 4bulb ATI T5 that I just finished refurbing. (I replaced my LED's as well, but from what I read, it's the T5's driving this) My tank is a 120XL, so 26" tall, and started the t5's at 12inches above the water. What I'm getting are daily APEX pH alarms as my pH spikes. I know pH is cyclical, and I read that introducing t5 could cause increased photosynthesis causing increased pH, but at it's lowest my pH is 8.18 and just yesterday, climbed as high as 8.47. I thought 8.3 is the highest you want, but my overall question is will this settle back down once the corals get accustomed to the new lighting? Any help and insight would be greatly appreciated.
  2. Do you have a link for it? Might help.

    t5 DIY

    This week the blue channel on my LED crapped out, leading to me to look at my options, and realizing how overpriced this industry can be. Slap on 'Marine' in front of everything and there goes a 200% markup. Which gets me to my point. If I want to do t5's, can I not simply buy a regular t5 HO fixture from HomeDepot or a gardening supply store (grow light) and use it? I look at the ATI's and other vendors and for $600+, can't seem to find the value in some sheet metal and a couple of fans. Maybe I'm missing something. For sizing, I have a 120xl tank, 18wide, 5ft long.....would 48" length be adequate or would the full 60" be ideal? I couldn't find sizing recommendations.
