Hey Mike, so this past weekend I went home to visit friends and family, and of course my old local fish stores and reefing buddies. 2 of my friends have started using Coral Snow and Coral Vitalizer. 1 of those friends is using my EXACT same 75 setup, and this is the only thing he does different. His zoanthid and palys have fingers almost an inch long..His sunny D's were like mini anemones. This guy is also asking me for tips since I am a Z/P collector, but his looked better than mine! So I did some research..and the Coral Snow acts as a water clarafier, which explains why his water was so clear, and it also enhances tentacles/polyp growth, and the Vitalizer is a coral food. I have a Nuvo 16, and I ordered a 250mL bottle of Coral Snow, and a 50mL bottle of the coral vitalizer. They will be here tomorrow. Together they costed me about 100$. I plan on doing a results thread, posting results every 3-5 days. So if you're interested to see how it effects my corals, I'll share the thread with you when I start it. Should be tomorrow or Friday. Hope his helps! I wouldn't have spend 100$ if I didn't think the results were awesome.
