:happyfish Hi, I've never used that product, but I use Kent marine phosphate sponge in my reef, I use it for about a week for removing the excess phosphate, that is a frequent problem in saltwater tanks. All of us, go through algae blooms from time to time. Just make sure your doin maintenance like your suppost to. Also, with the time of year it is, all of us are getting more natural light in our houses, and that is the culprit a lot of the time. Just make sure the blinds that are closest to tank are closed. Also trie to cut down on the time your tank lights are on, just check how low your suppost to go, and also, try feeding your fish less, and making sure any uneaten food scoop out and dispose of. Good luck, alison
