Help please Rainbow Chalices....

[Darren]

Is there a general concensus on what lighting these do best under? My tank is 24 in deep and for light I have one of the Powermodules with 75W LED and 4 24 watt t5's. The T5's are 2 blue plus and 2 purple plus. The light is about 8 inches over the tank and the chalices are in the sand. Thanks!

For chalices, the most important element is dKh.

High or low DKH?

I've kept mine under MH, T5, and LEDs with good results. Water quality, stability, and food are most important. I keep my calcium above 420 and alk above 9.0. Here's one of mine that keeps getting better

Chalices like high magnesium or at least they do in my tanks. Indirect light is good and feed them twice a week and they will grow well.
