Well, the clam died and I am not really sure why. Maybe it was the coral snow or maybe I wasn't feeding it enough? I feel very bad. One condition very different from the Crocea that I was so successful with years ago, is that I had a T5 quad back then that was only 3" from the surface of the water. Now I have a ReefBreeder Photon that is 14" from the surface of the water and I have never measured par so that may be the big difference. Anyway, I think I am done with clams for now.
Also my pulsing xenia are all closed up. My nutrients are high (NO3 20 and PO4 .8) but I did not think that would bother xenia. The sps are encrusting and have great color. The trumpets are making more heads and the torches and frog spawn all look great. All the zoas/palys are spreading so in general the tank is doing quite well. And the 'uglies' on the sandbed seem to have run their course and are mostly done, which looks so much better.
I bought a Jabao dosing pump. I am hand dosing 40ml of AFR daily and I need a plan for an upcoming vacation in August. It should arrive Monday and hopefully I can figure out how to use it!
