    Pro Clear "ProStar Filter Sock" 150 Micron Ultra-Fine Thick Mesh Furred 3.75"Dia x 6"H Filter Sock with Plastic Ring (for Pro Clear ProStar Tank Systems)

    Great tank

    Would recommend! Super easy setup and very nice quality feel to the tank and stand!

    Good Quality Light!

    Purchased this extra UV light for my new unit and I couldn’t be happier that I did. I should be set for the next two years now!

    Great quality UV light!

    This unit is a good fit for my Prostar 200 Aquarium. I was able to custom plumb it into my return line by horizontally mounting it just above my sump. Within 12 hours it turned my water crystal clear and undesired Algae growth has already gone down significantly. If you plan on running a heavily stocked aquarium then you need one of these units carefully matched with your systems flow rate to be truly successful.
