    I have a small pondless fountain that's cloudy and slimy. What can I use to clean it?

    A:  Pondless, fishless water features are known for being low maintenance – but even they get slimy and scummy and in need of some attention. Dust and debris blow into the water, leaves and twigs somehow find their way into the basin, and algae starts to grow on the surfaces. As all that stuff builds up and breaks down, you're left with a mess. Good thing it's an easy problem to manage. Because you have no pond and no resident fish to consider, there's no need to worry about de-chlorinators, test kits, filtration systems and all that nonsense (although adding a filter... Read More »

    We've been keeping our fish indoors for the winter and have filtration. Do we need to use any chemicals?

  • What do you really mean when you say fish are "dormant" for the winter? Do they sleep?

    What do you really mean when you say fish are "dormant" for the winter? Do they sleep?

    A:  When the days shorten and temperatures drop, koi and other pond fish enter into what's called torpor, or a period of decreased physiological activity that allows them to save energy. They don't sleep the winter away, but they do essentially hibernate—their metabolism slows, they require less food, their activity level drops and their body temperatures reduce. How do they know they need to hibernate, and what can hobbyists do to make their finned friends' winter torpor restful? Read on to learn more. Mother Nature's in Charge Fish don't use calendars to...

  • What can I do to prevent string algae from growing in the winter?

    What can I do to prevent string algae from growing in the winter?

    A: Even in the cold of winter, string algae can grow in your water garden. All that green nuisance needs to thrive is the right amount of nutrients and sunlight. So what can you do to prevent it? You have three options in your pond management toolbox: Seasonal Defense ® , barley straw extract, and a three-in-one pond tool. Boost Your Bacteria First of all, you'll need to control the nutrients – or the food that the algae eat – in your pond. Because the beneficial bacteria that break down those nutrients go dormant in the winter, now's the time to add some... Read More »
