Rated 5 out of 5 by LOVEMYCORAL Great product
This product is the best way to take out phosphates. I put a few drops in and my phosphates were gone. It doesn't take a lot of time like medias. The only negative is you have to test your water, so it's not for beginners. Its also more cost effective than any media you could use. If your looking for the cheap most effective way to remove phosphates this is it.

Rated 5 out of 5 by Bob66 It works extremely well and fast
Was having problems with Tap Water already containing fair amount of phosphate and tried numerous products using filter bags and pouches with no luck in the short term. A few drops of this and the problem was solved and levels went back to pretty much zero within hours. What a difference and without all the mess of the other stuff. Highly recommend. Be sure and only dose according to directions.

Rated 4 out of 5 by pflegadocious Easy application, effective
When your tank has to endure that period of a couple of weeks of neglect, this product is a quick and easy fix for your reef. Simple dropper method into high flow region disperses the product. Coral responds within 24 hrs. to the lower levels of phosphate. Algae thins out within 3 days of first use.
