The smaller of the 2 is a biocube 32. The doser runs 4 times a day at 12 ml each time, so 48ml. I have SPS, zoas, nems, xenia, a torch, acans & nems in the tank. Its been running with this setup for several years. If you look back to the sps colony I lost due to the big hurricane (Lauru I think) that hit Louisiana you can see the growth I have. It was the size of a volleyball, in a little biocube. I run my ALK around 8.
My biocube also has the RapidLed Kit added, so the LEDs are very bright & powerful.
