Q: How do I know if my filtration system is adequate for my pond?

Roger – Grayson, GA

A: Clean, clear water is a must-have in any water feature. It allows you to see those gorgeous koi and goldfish swimming below the surface. It shows that you have excellent water quality, with plenty of oxygen for your pond’s inhabitants—including the microscopic ones, like beneficial bacteria. And it puts off no offensive odors, which means you can host shindigs by your water garden without scaring off your friends.

When your water quality is suffering, your pond is telling you that your filtration isn’t up to par. Here are four clear signs that say you need to kick it up a notch.

  1. Algae Blooms, Clarity Concerns: If you have a filtration system in place but you still have water clarity issues and algae blooms, that’s an obvious indicator that you need an upgrade. When selecting a more powerful filtration system, like our AllClear™ PLUS Pressurized Filters with a built-in ultraviolet clarifier, make sure it’s sized appropriately for your pond and its nutrient load.
  2. Fish Frenzy: If your pond’s resident fish have multiplied and grown over the years, then you’re likely overdue for a more powerful filter system. Most filter systems are marketed for a minimal fish load, so too many fish producing waste will overload the system. Remember: The rule is to allow 1 inch of adult fish per square foot of surface area. If you have too many koi or goldfish in your pond, you should think about finding new homes for some of your finned friends or increasing your filtration.
  3. Toxic Test Results: Test your pond’s water with one of our Master Test Kits to find out what your ammonia, nitrite and phosphate levels are. If you see high ammonia levels or if your fishes’ health has been suffering, the pond lacks proper filtration.
  4. Foamy Falls: Have you seen foam build up at the base of your waterfall or stream? All that frothiness, which is caused by excess protein and oil excreted by fish and other pond dwellers, can be a sign of excessive nutrient levels caused by inadequate filtration. A higher-powered filter system can help remove and dissipate that foam.

If you have a waterfall filter box, you can easily boost your filtration system’s water-cleaning power by adding Matala® Filter Pads. With four different densities—low, medium, high and super high—you can mix and match them to suit your pond’s unique needs.

  1. I have 2 garden ponds, one of which is a 90 gallon preformed ,inserted into the ground. All winter I had a deicer and an aerator in it, but I looked at it today and see a lot of what I believe to be string algae. If I put a brush in it and twirl it around, as if I were pulling cotton candy from a machine, it wraps around the brush and some will dangle down from the brush itself, as I pull it out of the water. What can I “SAFELY” use to rid some of that algae? The reason I say some ,is because there are no fish in it, but there are Frogs and tadpoles that I do not want to kill.All products I read labels from. do not mention that the ingredients are safe for Frogs and Tadpoles. I believe that tadpoles will eat algae, but I feel I should remove some. Please advise. Thank YOU! PS there is also some leaf debris on the bottom.

    • Hi there – Chemicals for algae (such as AlgaeOff and AlgaeFix) and debris are safe for frogs, tadpoles and wildlife when used in accordance with label instructions. As with any chemical application, ensure proper aeration is being used for at least 48 hours after application. Removal of dead algae is also recommend to make sure the algae cycle doesn’t start again. Other options for algae control include: adding plants, continue to remove string algae with a brush, or natural bacteria (such as LiquidClear).
