    I have a 25 gallon tank that has been set up for approx 6 months. All of my wter parameters seem to be alright except for a high phosphate level. Can anybody recommed a solution, or have any idea where it may be comming from?

    Tank Details

    30 Lbs fiji rock
    20lbs Aragamax sand substrate
    Filtered water used for topoffs and water changes from local Superstore. Supposed to be RO/DI 10% water changes weekly.

    Ammonia 0
    Nitrite 0
    Nitrate 10
    PH 8.1
    Temp 80
    SG 1.024
    Calcium 420
    Phosphate 0.5

    1 Tomatoe Clown
    1 Manadrin Goby
    1 Pepermint Shrimp
    2 Blue Legged hermits
    4 Turbo snails
    1 Red Marble sea star

    100 watt heater
    Seaclone 100 Skimmer

    what are you feeding? have you tried other phosphate media (such as PhosGuard)?
    you dont look like you have an algae problem, so it may also be your test kit that is off, try with a Salifert kit.

    I feed 1/4 to 1/2 cube of frozen mysis shrimp every day, and a pinch of freeze dried Cyclo-eeze every other day.

    Ive heard good things about Phos-gaurd. How do you use it?

    here is a thread from Reef Central in which i discussed the use of PhosGuard directly with Seachem (the manufacturer). I hope you find it helpful.

    there is a thread linked from my thread above discussing issues with RowaPhos. I believe Robin (from AC/here) also is switching from RowaPhos to PhosGuard.

    Many experienced reef-folk and other reputable sources have stated the use of PhosGuard causes very bad reactions in corals.... especially leathers or "softies".....

    I experienced this phenomenon personally, about 2 years ago with my big toadstool... it closed up after a PhosGuard treatment and was never the same for about a year.... it's on the way back now....

    After discussion with other experienced reefers I have come to the conclusion that the "Iron-Based" phosphate removers are your best bet... :thumb:

    For your personal info... the PhosGuard is "Aluminum-Based"....
    It's not junk, it's un-assembled DIY!

    One question. Im not currently running a sump, so would it be alright to run the Phos-gaurd in a media bag in my HOB filter?

    Thanks again.

    There is a good article in this months reefkeeping.com I think the problems start to arise when the phosphates are totally removed from the water. Has anyone heard of Marc Weiss Phosphate Magnet? I started using it two days ago, I'm going to see how its doing today.
