do any of you add it or do you think you should be? what are the benifits?

[Twistedpro]

I dose iron but in low levels it really does help to increase green acro's. You can tell if you have overdosed with yellow acro's as they develop a green tinge and algae growth continues

[ben]

do you test for it or just have a weekly amount you add?
is it only the green ones you notice or do you think it helps the others too?

[Twistedpro]

No i dont test for it, i normally judge by the look of the corals. With the Zeovit system you can alter the colours depending on the supplement. If i want to boost green then i use iron, if i want to enhance blue i use Pottassium iodine flouride etc.

It can brown out your corals also as it will increase the zooxanthallae also

[ben]

sounds like a risky addative

[Craig Robbo]

It can really give you algae issues TBH Ben.
