i have turned off my daytime lights yes, but not my actinics.
that clam is actually part of my live rock and has been doing well. i'd have to break apart my rock to get it out.
i have a pink and blue shrimp goby so i dont think i can get a sand sifting one, sides i'd have to qt it for 3 weeks and by then... :scared:
i thought stars were not all that great since they eat beneficial organisms out of the sand and not the cyano itself. i do though have a bristle star so i don't know if it would be ok with a sand sifter.
