Over the past couple of months I changed out the lighting. While the Mitras LX7 is a very good light and is aesthetically pleasing I just couldn't seam to get it to where I really liked how the tank was lit. The LED just had too much shimmer for my liking and I could see ever so slight light separation. I think the screen top could have played a partial role in this. I spent way too much time adjusting and worrying about the lighting.
My solution was to first get an ATI 4-bulb Sunpower. I was running the Sunpower with (2) Blue Plus, Coral Plus and Actinic. I then added a Reef Brite XHO Actinic Blue to the front of the Sunpower. I really liked the addition of the XHO so I decided to add a second to the rear.
For my tank two XHO and four T5 would be too much light (roughly equivalent to eight T5) so I stopped running the two Blue Plus bulbs. The configuration was now (2) XHO, Coral Plus and Actinic. With the fixture mounted around 8" above the water I was able to achieve my PAR goal of 120-130 PAR on the sandbed.
The 4-bulb fixture and (2) XHO created a couple of "problems".
The first was to have an even spread into the tank from the T5's I wanted them to be the two center bulbs in the fixture. I fixed this by rewiring the ballasts so the center bulbs were a pair and the outer bulbs were a pair.
The second was the rear XHO hung too far back and around half the light was spilling out the back of the tank (see last photo). The display area of the tank is 18" wide. I tried angling the rear XHO forward for a time to make the 4-bulb fixture work, but this resulted in light shining into the eyes.
The only solution I could see at this point was to get a Reef Brite Supra Slimline dual lamp fixture.
I have the fixture mounted 8" from the waterline and I'm seeing PAR in the 130 range. I was a little concerned with what the aesthetics of fixture may be since I couldn't find any photos of one installed, but I think it looks just fine. When looking straight on you don't even see the T5's.
Since installing the T5s just over three months ago I've noticed increased growth and corresponding increase in consumption to where I've started dosing. I'm dosing BRS soda ash and calcium chloride along with Tropic Marine Part C. I'm manually dosing 7.5ml of each per day, maintaining alkalinity around 8.0 and calcium around 420.
I'm having a hard time taking any decent photos in the tank, once I do I'll post some up and update what's going on inside the tank.
