    Recently acquired 5 cold water fish and 45litre tank. There is a filter, pump and air stone in the tank but within days of cleaning the water is green with algae. We are using fish safe when adding new water and algae control. There is gravel and a small bridge only in tank. Bought plants to try and help but fish ate the lot.
    Please help!
    Thank you

    Hi. Welcome to PF. :)

    Algae problems are usually caused by an imbalance of nutrients. Shame the fish ate the plants, because plants can outcompete algae for those nutrients.

    Reducing the number of hours the tank lights are on, and reducing the amount you feed the fish are two ways in which you can try to combat algae. Regular water changes to reduce the amount of nutrients in the water might help, too.

    Do you have a test kit for ammonia nitrite, nitrate and pH?

    What fish do you have?

    Is the water column full of algae or is it growing on the items in the tank? Also as @LinznMilly said, "Do you have a test kit?"
