Green turned to Clear
New tank owner and within a few days my tank was ugly green! I did my research and found I was using too much light on my tank. Problem solved but still had the green mess. I used Marineland and crystal clear within 2 day.

    Make your own filter pads
    This is the best quality charcoal for making your own fish tank filter pads. It keeps your tan very clean and you can decide how much of it you want to use. The Walmart price for this size is excellent!

    Compared same weight elsewhere. Hands down this is the place to buy. Plan to put this activated charcoal into sachet holders and hang throughout house, to kill musty odors and prevent mold. One container can make 10-12 sachets. The retail market sells these for a lot more than these will cost me to make.

    The best carbon that I've ever used. Cleans better than any other products I've tried.

    Crystal clear water. Happy!
    Wanted to give my tank that extra clean without disturbing my biological filter and sand bed. Matched with new polishing filter, my tank looks like my fish are floating in thin air. Great product to use once in a while.
