Post a photo of your dirty aquarium on our Facebook page by January 25. We'll send the 5 dirtiest tank owners a package of PURE Marine that contains approximately 50 bacteria/enzyme balls for you to treat your tank. All we ask in return is that you post an AFTER photo on our Facebook page to tell us what you think about the product. Winners must be U.S. residents 18-years-old or older to win. *Some restrictions apply. Read Official Rules.


How to Use PURE Marine

You can use PURE Marine as part of your regular maintenance program. You cannot overdose with PURE Marine. To maintain crystal clear healthy water, add 3 x PURE Marine balls for every 10 gallons of water once per week into your marine aquarium filter. Alternatively, place the balls in a filter bag and position in the tank or the filter in an area with good flow.
