Brightwell AquaticsCoralline Accelerator - Multi-Nutrient Supplement for Coralline Algae Growth in Marine and Reef Aquariums - Aquarium Water Treatments, 8.45 fl oz

I have tried other products not all but a fee and this is the only one thus far that has produces coralline in my tank not just the overflow box. It works as it promises without any negative side effects.

Great product! I’ve had great success with all products from Brightwell. This was no different and I was able to build some good coraline in all of my reef tanks. Easy to recommend!

The product clouds he water so use in the evening. Works great.

It is definitely helping. makes the water cloudy for a couple hours.

Shocked at how fast my stony corals are growing with this supplement. Perhaps I'm missing something in my regular dosing but adding this literally made my corals take off.

I have been using this for about 3 months I am just now starting to see new growth on "Live rock". I am ot sure if it just started growing on its own or if this promoted the growth. My apology if this is not a helpful review. This is my first try at a saltwater reef tank and my first try at growing Coralline algae. I was told the "live rock would take off quick and I bought 2 of those. The first one "Petco" has nothing and the newest one (a fish supply store) only a few weeks old is growing Coralline like a champ! i used as directed.

Excellent, it's basically calcium with trace elements. Works as intended and I trust Brightwell with my reef.

Amazing stuff within 3 days my corals looked brighter, used in combo with some other brightwell aquatics stuff and looked great. I would say amino acids first if your on a budget that had immediate impact.
