  1. Default Suspended algae problem

    0 Not allowed!
    I have a 120 gal freshwater tank with an eheim g160 canister filter
    And my water is greeny and not clear. I have been told this is suspended
    Algae. I have tried chemicals and a max clear product that is pebbles
    That go in my filter. Nothing seems to work. I change my fine filter every
    Month. The tank is only two months old so I haven't reached the 6 month timeline recommended by eheim to start changing other parts of the canister. I remember having this problem in another tank and it was a spent charcoal filter. So I am wondering if I should start changing my other filter internals like my bio or course mechanical. Any suggestions would be appreciated.

    My water parameters are all in spec as I have been doing water changes to try to clear the water. I also add aquarium salt and have live plants

    Is your tank near a window? What percentage water changes do you do? How often?

    It is not near a window. I do however have a two lamp t5 light and two t8 for lighting for my plants which are on about 10 hours a day. Not sure if that's too much

    My water changes are 20-30% bi weekly but have been more frequent since the green water

    Jeffsdime! Geez louise man!! How ya been?
    Op. Drop your lighting amount to just the t5s,drop the schedule back to 7 hrs a day and up the wc to 25% a week and do gravel vacs weekly as well. Cut back to minimum feeding of fish and don't dose any liquid ferts til the green water goes away. Should take about a week and half with my recomendations. Stop using all chems,don't change your filter media at all,simply rinse it clean in nonclorinated water,never change your biomedia. Increase aeration as well.

    +1 to the above

    You could even change more water, like 50% every other day (or more)

    Have you tested for nitrates and phosphated latley ???

    Edit, I have also moved your thread to the correct section of the forum

    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.
