I just changed the bulbs on my nano cube and I am not too happy with the new color. I changed from a 36 watt power compact fluorescent 50/50 (half 10,000 K and half 7100 K blue) and a 36 watt power compact fluorescent true actinic 03 to 36 watt power compact fluorescent 10,000 K and a 36 watt power compact fluorescent true actinic 03. The full tube of 10,000 K really washes out the color in the corals. I think I will pick up another 50/50 the next time I am at the store or order one online if I can't stand it any more.
I added some new acquisitions today:
Pink Bird's nest Seriatopora histrix
Lady's pantyhose stocking with 4 oz. of activated carbon changed monthly, a 50 watt heater set at 78*F, and a Maxijet 900 for flow. No sponges, no bio-balls, no live rock rubble, etc.
that's all you have? by the look of your water it looks very clear it's just hard to believe that you basically only have 1 piece of filtration lol. Does that keep the big stuff out?
With the back chambers empty, most of the sediment and other junk eventually settles to the bottom back there. I do a water change every two weeks (~4 gallons) and every third or fourth water change I'll suck all the junk out of the back chambers.
I feel changing carbon on a regular basis really keeps the water crystal clear. It works for me!
New growth on blue Montipora digitata.
It is basically a cream color with a very faint hint of blue on the tips of the polyps under my PCs, but under halides this is the German blue monti.
