It is really good I will be getting more
Noticed a big difference using this but it's easy to put your calcium in the aquarium so I do like using the product I just don't know that it makes Coraline algae grow any faster

CaribSea Purple Up
Okay this product had mixed reviews but I really wanted the purple rocks sooo gave it a try. I have used it over two months and its very slow to happen. I just now have purple growing but it also grows on the tank glass where I want it clean to see my fish... didn't know that. I will cont to use this product until I finish it I use it at night before I turn the lights off only because it really clouds up the water and hate to see that during the day by the time the lights come on in the morn its crystal clear again. The fish, corals and starfish etc don't see to mind it although they hide when the cloud comes through... I wish it worked faster with less product but no such luck I will however cont to use this product because I like the purple look.. the price was fair and shipping out was fairly fast.

Follow directions, be patient, it works!
The only way to make sure this product works is by using its entire bottle as intended and be patient! Can’t expect coraline algae growth after a week!

PU is ok. Tropic Marin Biocalcium is the best.
I used two bottles of purple up over a 18 month period. I'm not sure if it accelerated coraline algae or not. I did notice some coraline but not much.I then educated myself and broke down and started testing CA Alk and magnesium. Once correcting these parameters I did notice accelerated coraline algae growth.Only after testing for CA Alk Mg did I have success with this product. I gave this 3 stars because I switched to Tropic Marin Biocalcium, on a recommendation, and my coraline algae exploded. I now have to scrape it off the front and sides of my tank. If I could give tropic marin Biocalcium 7 stars I would.
