Q: My koi didn’t spawn last year. How can I get them to spawn?

Judy – Springfield, MO

A: Sounds like your koi were being a bit coy last year! If you want your fish to get frisky this spring and produce a brood of colorful fry, break out the bubbly and try out these tips and techniques that will create the perfect mood for love.

  1. Create Ambiance – Your koi don’t need soft candlelight and rose petals for romance, but they do prefer an aquatic environment that’s as pristine as possible. Perform regular water changes – that’s changing out 10% to 20% of your water every two weeks – to help keep things clean and clear. Once water temperatures climb back up to 50°F, you can also begin adding the water-quality-boosting products found in DefensePAC®, like Seasonal Defense®, Nature’s Defense® and Clarity Defense®.
  2. Heat Things Up – Temperature and time of year matter when it comes to koi feeling amorous. The fish typically spawn when water temperatures are 65° to 70°F. In many ponds, this typically happens between May and June – in late spring and early summer, when the birds and bees start to get busy!
  3. Give Them a Love Nest – Like you and me, koi like their privacy when it’s time for them to mate. Before spring settles in, make sure you give them plenty of cozy spots and hiding places. Plants, tunnels, and Nycon Koi Kastle Fish Shelters will provide excellent coverage for them. In addition, give them a safe place to lay their eggs, like a fry mat or similar device.
  4. Know the Signs – When you see the male koi chasing after the females, you’ll know the game of love is on. Keep an eye on their behavior; however, because the males might try to run into the females, or push them into the rocks and the side of your pond to try to get them to release their eggs. Another telltale sign: Cloudy or foamy water accompanied by a distinct odor.
  5. Keep the Fry Safe – Once the fry emerge from their eggs, they can’t swim and will need a protected area that’s safe from natural predators, like tadpoles, frogs and koi. Make sure you give them plenty of coverage with water hyacinth, water lettuce and other aquatic plants. You might also consider using a fine mesh tent, like the Nycon Fish Spawning Incubator, to protect them and prevent them from getting sucked in and lost in your filtration system.

With a little staging and encouragement, it’s not too difficult to convince your koi to spawn. Follow these tips, keep the brood safe once they hatch and, before long, you’ll have a pond full of small fry! Good luck!

I think my aeration airline is clogged or frozen. What should I do? | Ponds & Lakes Q&A

A: We all know how important an aeration system is in your pond or lake – but it doesn’t do much good if your airline is clogged or frozen! If you don’t see bubbles at the surface and your compressor is running, here’s what we recommend to troubleshoot a closed line:

  1. Gauge Check: First of all, check your air pressure gauge. Is it reading higher than normal? If so, your compressor is struggling to push the air through the blockage, which is creating increased pressure in the line.
  2. System Check: Next, disconnect the airline at the compressor and check to see whether air is coming out. If it is, your compressor works just fine – but your airline might have ice blockages. To melt them and open the flow back up, pour 1 cup of isopropyl alcohol through each airline (or the airline you believe is clogged or frozen).
  3. Maintenance Check: If no air is coming out of your compressor, you might need to do some maintenance on it. Over time, seals and moving parts will wear and break down, causing decreased system performance. The Pond Logic® SilentAir™ Piston Compressor Maintenance Kits include a range of washers, gaskets and hardware that will get your compressor humming again.
  4. Air Filter Check: While you’re doing maintenance on your air compressor, it’s a good idea to check your air filter, too. If it’s full of gunk and debris, consider replacing it with the SilentAir™ RP Series Compressor Air Filters. They’re designed to be replaced every three to six months for maximum system performance and longevity.
