For starters, I have a JBJ 28g CF
Quad Nano Cube that has been set up for almost 1 year at this point. This was my first venture into the salty side, and it's been a great learning experience along the way!! Sometime back in December, I replaced the stock lighting with an 18" 150watt metal halide fixture. I began to accumulate all the typical animals that these lights allow us to have, ie, a clam, LPS
corals, and SPS
corals. Things went great with good growth and lots of color!
On July 1st, I decided to run an experiment with the original lighting that came with this aquarium to see if it could not only sustain animals that were more light demanding, but rather get them to thrive For those that don't know, the stock JBJ 28g CF
Quad comes with a 105watt 50/50 compact fluorescent bulb. The tank dimensions are 18"Lx22"Wx22"H.
To my surprise, the few hard corals and one clam that I left in this system have done very well! In fact, one birds nest frag that started out as one branch about 1" long has only been under this light since purchase! Below are a few pics of the corals...
I just thought I would share my little experiment. I think if the bulb was a little more evenly spread with the white and blue, the color would definitely show up more. Unfortunately, the actinic portion of the bulb sits back, this a lot of colors don't pop as much as they could. That being said, the growth is there, along with the color on those corals getting some of the actinic. I'll try and post an update in a month or so. Who knows, this light may be a little better than we think...
