Actually got 2 Tim, lol... They are doing a fantastic job of keeping clean sand. My CUC is really an emphasis with all my tanks. I have so many various members of the crew, as I have a 20 gallon mangrove fuge that houses my back ups. This way, I can reboot occasionally by bringing them over, as the fuge has no predators, so they flourish. I have mysis, pods, stomatellas, limpets naturally reproducing, as well as within my DT. I am kinda a junkie for CUC stuff, I have already spent a few hundred on my new tank alone, lol. That's why my coral and fish budget has been lean. Today, I will be trying to purchase a CBB, as the aptasia thing between the file fish and 10 peppermints seems to be unimproved. I know this isn't really sps related, but anyone that has ever sought my advice, I usually emphasize CUC, and the need for as much micro-life available, through seeding kits, fellow reefers, whatever it takes. In turn, this enables diversity, balance, maturity, you know, 80-90% of "my sps are dying" threads. I have been lucky to have transitioned my tank over so smoothly, much to do with my rock

Cheers
