    I have an algae problem, and it is in the biofalls and filters. I have increased the number on plants and I'm hoping that will stop the growth.
    But in the mean time, should I remove the filters and clean them, they look to be completely saturated in algae blooms.

    With all this rain and humidity we have been getting in southern Ont, I have been having algae problems with my pool.......Of course, I can just lace the chlorine to it.....lol

    With less humidity right now, I bet it tends to clear up.....Yes, I would clean your filters

    Plants will help, but it will take time.

    What type of algae is predominant?

    Your system has not been up and running continuously for very long, has it? I doubt if your NitrAte levels are a result of bioconversion as it usually takes 4 - 6 weeks average for a bioconverter (filter) to fully cycle. Your problem is most likely caused by the NitrAte levels of your source water.
    Cleaning your filters will only set back the bacteria growth in the Biofalls. DO NOT CLEAN THEM!
    Algae blooms are quite common in a new system, especially when the system is brought on-line when the temps are already high or rising. Once the Algae and the larger plants have reduced the NitrAte level, the algae will begin to die off and the larger plants will dominate. You will always have some algae. It is beneficial. What you don't want is filamentous (string) algae or suspended (Pea Soup) algae.
    It takes a full year for a system to completely stabilize or "mellow". Don't start throwing chemicals at it if you want to have a naturally balanced system.

    What did you use for filter media?

    95+ temps the last month has blessed us with green water also. ::)

    I did clean the filters and it has helped a lot. The water is still a bit green, but no where near what is was. It was so thick in the biofalls, that it affected the flow of the water.

    As to the filter media....just what came from Aquascape. Two black (previously green..LOL), and the bioballs.

    By chance, did you allow water to stand in the Biofalls during the time that your system was shut down while you were looking for your leak(s)? If so, that gave the algae a foot hold in the filter.
    Water should clear fairly quickly.

    A UV light will clear the algea bloom right up within a few hours and keep it that way.

    UV lights will only clear up floating algae. The algae must pass through the UV module to be affected. This really doesn't address the underlying cause of the algae bloom, only the symptoms.

    This post is from last year, but it is still in my head.....
    I purchased a IonGen inline water clarifier/algae killer over the winter and put it in my skimmer where the water can flow through it quite easily. I went away for a 2 week boat trip and came back to brown algae.
    What';s this all about?
    I've taken the power washer and cleaned it off the boulders and rocks that are directly in front of the waterfall.
    I also have some ECOBLAST, that is supposed to get rid of "debris" in the pond.....I'm guessing that means algae.
    Will this stuff harm either the fish, or the plants?

    And if I use if will it clog the filters with all the "debris" and should I clean them?

    Thanks in advance
