? for those with large zoa tanks

[Chriskid]

has any of you noticed specific elements being useed by these animals more then others?

iodide, strontium, potassium, ext.

[650-IS350]

good question. I don't dose extra elements even when I had my 100 gal zoa tank. Only used 2 part dosing. I only poured in live phyto culture that I was breeding and also tiger pods.

i do not replenish elements via water changes. i add the three i mention to keep stable, being my reef is mostly SPS. im still trying to find out why some palys seem to slowly go backwards after a while. my iodide was just .01, so i brought it up a hair. reef is 1year old.
and SPS are doing extremely well. most zoa aswell. just a select few species not. trying to find the missing piece to the puzzle:)
