I'll try to get some soon. I changed the tank up a bit, so hopefully I'll start to see some more growth.
The changes:
I added a reflector to the 70w MH bulb in the hood of my BioCube. It's just the one out of a Brinks halogen flood light.
I gave the tanka good cleaning. The frag racks were allowing a lot of detritus to build up on the sand bed, so out they came. I popped the frags (all zoanthid) off of the tiles and glued them to new live rock. Now the 'project' is the centerpiece and there are other zoa frags set up to cover the rocks below.
I built a filter of sorts for the top of the 2nd chamber. It is just a filter sock piece zip tied to egg crate that is cut to fit the opening. It just drops in to polish the water and is quick and easy to remove and clean.
Lastly, I added a Randal's goby and pistol shrimp. They've burrowed into the front right side of the tank, so they're open for all to see.
Hopefully the improvements will help growth.
