When should I start using the Seasonal Defense® in my DefensePAC®? | Decorative Ponds & Water Gardens Q & A

When should I start using the Seasonal Defense® in my DefensePAC®?

Q: When should I start using the Seasonal Defense® in my DefensePAC®?

Chuck – Essex, MD

A: Pond Logic® Seasonal Defense®, which is sold separately and as part of Pond Logic® DefensePAC®, contains aerobic bacteria that’s specially designed for cooler water. In the spring, it replenishes bacteria lost over the winter, jump starts the growth of the waste-gobbling microorganisms and breaks down accumulated waste. It’s a great way to kick off pond season!

Add It At 40 Degrees

Plan to start treating with Seasonal Defense® once your pond is up and running and the water temperature is greater than 40° Fahrenheit. You can expect to use it for about one month, or until the water hits 50°F. Once the thermostat tops 50°F, switch to Nature’s Defense®.

Distribute Evenly

Don’t just pile the Seasonal Defense® packets in one place in your pond. Put a packet in each corner to ensure even spread of the beneficial bacteria and breakdown of accumulated muck. Add some to the filter to concentrate and accelerate new bacteria growth on the filter media. Distribute them evenly—but, of course, follow the package recommendations for dosage rates.

Help the Bacteria Work

Don’t forget to aerate the pond and give it an old-fashioned cleaning to make those bacteria’s jobs easier. Along with running your pond’s pump and filtration system, keep your aeration system going to help move the water, add oxygen and disperse the bacteria throughout the pond.

And before you add the packets, clean out any large debris from the pond. Branches, dead foliage, fallen leaves and any other easy-to-remove organic materials that wound up in the water over the fall and winter should be removed so that the bacteria can better spend their time breaking down fine debris and muck.

  1. HI Jason! I just ordered your Seasonal Defense, and Nature Defense for later. Will these products control what was hair algae that grew on liner over the winter?
    Just want to rid that, and develop clear water again!

    • Hi Bruce – Seasonal Defense® and Nature’s Defense® do not kill any current growth of string algae. Both products will control algae growth by using the same nutrients that the algae does. By eliminating the food source for algae, we will stop it. We recommend removing as much of the string algae as possible from your pond as possible. Oxy-Lift™ Defense® will help to remove any string algae that is stuck on rocks or your waterfall.

      • Thanks for the note. OK to use UV with these products?
        I also had a note in to your site, asking about adding a Skimmer to an existing linered pond? Difficulty level and product suggestions?

      • Bruce – As long as your pump is properly sized to your UV light, your beneficial bacteria will be just fine!

        Adding a skimmer is sometimes a bit difficult to add to an existing pond. If you want a heavy duty skimmer, you’ll need to make sure you have enough liner to cut and fit in the skimmer. Here are our available skimmers. Your other option is the TetraPond® In-Pond Skimmer. This hooks hooks up to a pump and sits inside the pond. You do not need to cut into the liner at all.

      • Thanks again for the reply! 3rd year pond and I’m trying to get it right 🙂 Looks like the In-pond skimmer needs to sit on the bottom? My depth is 3+ feet deep.
        Regarding liner, can new liner be layed-over old liner to gain height and still seal?

      • Hi Bruce – If you do not have the ideal depth for the skimmer, you can always had bricks or rocks to bring the level up. As for liner, you will need to lay new liner over the old liner and use sealant or Double Sided Seam Tape. Please remember that anytime liner is seamed together, you will have to be cautious of leaks. This is typically one of the first places to leak (along with waterfalls and streams).
