    For the past two years I have had great results growing duckweed for profit and selling it on Ebay. But the last few months my grow out tank the duckweed has quit growing and is starting to die out any idea what would cause this? I have a active guppy colony in the tank and it's fully established before my Duckweed would double every month or more. I use basic sponge filters for filtration nothing has changed in the tank other then the fish stock doubling.

    Has it stopped reproducing or are the individual plants dying, or both?

    Probably a mix of both the population looks small compared to the last time I harvested and the water has plenty of room for new growth.

    Any yellowing, smaller roots or anything? Any less fish or anything?

    Maybe you should test nitrates if you’re really concerned.

    The water levels is fine and the remaining duckweed seems fine I'm just curious why it isn't growing.

    Well it's summer so the temp has changed but the lighting is the same and on a 12 hour on/off timer.

    Just started
    Lighting is the same with an 8hr on 16hr off
    And I only recently (within the past couple days) increased the water temperature very slowly to 79-80 where it used to sit around 76-77 in hopes that it would help with the coloration. Although my dwarf guarami is very vibrant in color and shows no signs of stress. Nor do the black mollies and Albino Corys
