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.
