It is almost three months as azoox cube was set up. Thank you all for warm words and comments. This tank made me rethink a lot of things about reef keeping. There is very little information on keeping azooxanthellae corals, so all research and development mostly done in hobbyists' tanks. Despite this there is good news. My crinoid finally smarten up and move from sitting on top off big power head( power head cause some leg chopping issues) to sitting on top off small power head. He is regrown his legs back, which is a good sign, that he gets enough nutrition. Tukas are going strong and maintaining unbelievable colors. NO3 was climbing up for past months, but biopellets are getting this problem under control. Thank you again for following this thread.
Cheers, Roman
