    Greetings!
    I have a 5 year old 700-800 gallon pond with a 3-4 foot waterfall. The skimmer/filter box has a pump that pumps the water to a waterfall box at the top of the falls where it goes thru 2 more layers of filter.
    I have 2 red earred slider turtles who devour any type of water plant I have tried, so I have pretty green water from algae. I was given a 20watt pondmaster UV clarifier to try and I would love some advice!
    I have a 2nd pump ( 1000 gph) that I placed in the waterfall box and connected the UV light to it. I have a temp hose connected to uv outlet that runs down the waterfall.
    My 3 questions:
    1) is the 1000 gph pump too powerful for UV effectiveness? If so, can I put a valve between the pump and uv light to decrease flow rate without damaging the pump?
    2) how long should it be before I see the water starting to clear?
    3) the pondmaster UV unit wasnt marked for input or output...does it matter which end I connect the pump to?
    Thanks bunches for reading and any advice you may have for me.

    According to Pondmaster. for clarifying this UV will handle flow rates up to 1800 gph. However, the lower the flow rate the more effective a UV is. You should get good results with the 1000 gph pump.

    It may take a few days depending on the algae load.

    I second the motion! Pretty looking pond. Keep us updated on the UV effectiveness.

    Yes you can add a valve to slow the rate down and I would do so. No it doesn't matter which end the water enters or exits. You should see results in a few days if not either the water is going too fast or the bulb is old and needs to be replaced. If the light is on 24-7 then it should be replaced every year.

    If this is a used unit, be sure to check the outside of the quartz sleeve.
    If it's covered in limescale, no light will get through.

    This is how it looks today...clearer, but still a little green.

    It takes time and a crate with quilt batting in it and a hose pump to allow water to flow in will catch alot of the finer stuff and get it out of the pond

    Sissy-do you leave the pump to crate running all the time or just when you want to clean pond?
