never used anything...just a heavy feed,very heavy,my fish are fat like a pig and that does the trick,my SPS are growing very fast my zoas duplicate like crazy,have one just bought it a month and a half a go had 7 heads and now has 20+..all i dose is alkalinity and calcium

Another believer in fish poop feeding of corals here. I never fed my zoas, and they grow like stink!

I've used vitamin c if that's what your referring to for a long time , I don't anymore and theres no real noticeable difference that I can see.

If you need help with growth or colors maybe a little about your system and what your trying to achieve will help:)

Some zoanthids won't eat foods , well Not the ones you'll offer anyways as they are too large , some larger species like zoanthus gigantus or palythoas species will take meaty foods like mysis.

Besides photosynthesis , what they need is found in the water column , adding food won't hurt though as long as you keep the exporting of nutrients at bay with the importing of foods.remember the build up of too much foods is often a slow process that doesn't get noticed til agae takes hold which is way to late.

Hmm, I wonder how that would work for SPS?

Works great for zoas although sps may not appreciate it as they are high maintenance ......maybe dinner and a glass of wine?

Good point. I'll try that.

Don't forget the mood music!

I've been reading people dose a small amount of iodine to there systems with great success! I know I every tank is different I just wanna make sure mine get the best! Haha research, research and apartently long walks on the beach! Haha

If you want to talk zoas and see my system your welcome to swing by my place and see some in action , I know a thing or two about zoanthids I even have a couple ;)
