Comments: Did a cycle with a small bottle, had next to zero results. Not sure if it was this product, but I've had luck with Carribsea Purple Up

Comments: I REALLY saw instant purples when using this product. There, short, sweet no long review, just the truth lol

Comments: Seems to be helping. The rock was great looking but lacking life. I have had other products suggested by the local reef store and am not totally impressed after 3 weeks of daily use.

Comments: Only needed a small amount to get the best results. Super pop in coraline algae growth! Best added at night as it does cloud the water for a short period.

Comments: I use it with my new setup RSM 250 and coraline algea started to grow everywhere in just 2 months. It also comes with trace elements so I can dose just once a day. Using this and regular water change, I have everything in check. Highly recommended

Comments: it works good

Comments: My rocks have been having a very hard time getting coralline algae to restart. The thick bleached coralline (bleached suring curing) just would not turn purple, pink, anything. I added this to my tank, as directed and within 2 weeks, my rocks are turning purple, pink, and orange. And the bleached area is getting nice color again. My Ca is ~480, Mg ~1450 and dKH 12.

Comments: I am very surprised. I use Kent salt and suppliments but this Purple Tech has been ineffective. I love their products but am not happy with this one. Purple Up has been the best product in this category I've used.
