Hello everyone Im new to the group.and have afew questions on keeping zoanthids I have some that did really good for about 6 months , then started diying off well I got the diying off to stop before I lost my whole colony.Now I would like to know what I can do to to kick start a growing spurt? Are there any additives that these coral need more of ,and what should the placement be in the tank? How about water flow? High ,med,or low? Water parems. are good except alk which is a little high which Iwas told was because my calcium was low is this correct?I have a coralife pc with 4 65 watt light bulbs. thanks for any info. you can give in advance, and I'll let you know if I can get things turned around.
