Pond & Lake Q & A
Q: I see some algae in my pond. Is it too cold to treat my pond at this point? – Jack of Ohio
A: Algae has a tendency to grow in colder temperatures even when there is ice covering your pond. To treat or not to treat really all just comes down to the temperature of the water. Algaecides, like Algae Defense (or Hydrothol if your have koi or goldfish in your pond), are most effective when water temperatures are above 50-60 degrees Fahrenheit. If you are living in the southern climates, the water temperatures may be already high enough for an algae treatment. As for the northern climates, it may be best to hold off until the water temperatures rise above the 50-60 degree Fahrenheit threshold.

Algae Growing in a Water Garden During Winter.
Q: I shut my water garden down for the winter, but I still see some algae growth. Can algae grow in cooler temperatures?
A: In some cases, a pond that stays clean and clear through the summer can blow up into an algal nightmare in the fall. Shutting down your watergarden ceases the flow-through characteristics of the pond. This reduces the amount of filtration that occurs both mechanically (i.e. skimmers) and biologically (i.e. filterfalls). Since there is less flow, it is a good idea to bump up the amount of bacteria in the pond by adding Seasonal Defense Bacteria with Barley. These bacteria operate in cooler conditions and will greatly reduce the amount of nutrients in the water, and also contains barley straw to naturally help with the algae. Using Oxy-Lift Defense to scrub down your rocks will also help to remove any debris build up.

Picture of chara, an erected form of algae.
Q: I have been treating for Algae/Chara about every two months throughout the summer although with fall approaching (and cooler temperatures) should I still be treating it or should I wait until spring? – Paul of Michigan
A: In general we suggest that you wait until water temperatures are above 50°F: Although the real answer is that you can treat Algae/Chara anytime it is actively growing. In most cases (in the Midwest) you can start treating algae as early as March or April and continue treatment through the month of October.
Treating for Algae/Chara: Chara, although it looks like a plant is actually just an erect from of Algae.
When treating for Chara and/or floating algae always take in to consideration the following:
- Benefits of Chara: Chara unlike planktonic and floating algae is not always an eyesore and can benefit your pond in many ways such as: naturally filtering the water, providing fish habitat, and preventing more aggressive plant grow. Chara can be selectively treated in swimming and fishing areas in larger bodies of water.
- Treatment Area: Only treat 1/3 of your pond at a time, waiting 7-10 days between treatments to minimize oxygen depletion caused by rotting vegetation.
- What Product Works Best: In almost every case we would suggest using liquid Algae Defense due to its cost and effectiveness. Although if your pond contains Trout, Koi or Goldfish you must test for hardness before any treatments. If the water hardness is not above 50ppm then Hydrothol 191 should be used to reduce the chance of a fish kill.
- The Best Time of Day For Treatment: Treat early on a calm sunny day; this will give you optimal conditions for your treatments to work.
- Removing and/or raking dead Algae and Chara after a treatment (wait 5-7 days) can help prevent it from coming back in the future by removing excess nutrients.
- Always consider a proactive solution over a reactive one when possible consider aeration, natural bacteria and other alternatives for a long-term solution to your problems.

Q: How do you control algae growth in a small pond that will not affect the fish (trout) in it?
-Jerry of Harrisburg, PA
A: We always suggest to customers with a pond of any size to use an aeration system along with natural bacteria to help eliminate muck and prevent stagnant water. Using these products together will make pond management easier and in time will reduce the need for chemicals. As far as the algae you currently have, there are a couple options to get rid of it. They are Algae
Defense Algaecide and Hydrothol 191 Granular. If you use the Algae Defense, you will need to test your water hardness to ensure the carbonate hardess is above 50 ppm (parts per million) which is safe level for trout when treating with Algae Defense. If you do not wish to go that route or if your pond contains koi or goldfish, use Hydrothol 191 instead. Hydrothol 191 is a granular that will work both on algae and weeds.
Just remember, using only chemicals to control algae is a “reactive”, short-term approach. If you really want to gain control over the long-haul, then you need to be “proactive” and follow the 4-Easy Steps to the Perfect Ecosystem. Watch our 4-step video online to learn more.

Q: I have a pea-green algae problem. What is the quickest, safest way to overcome this problem? -Ruth of Starkville, MS
A: When dealing with planktonic algae or “pea-green algae”, it cannot be simply eliminated using a product like AlgaeFix. AlgaeFix works great on string algae or other patches of free-floating algae, but with planktonic algae, there is so much that you run the risk of depleting oxygen levels to a point that is unsafe for fish. One of the best ways to get rid of this type of algae is through the use of a UV Filter. As the planktonic algae passes throught the ultraviolet light, it will die. UV lights work so well that within just a few days your water will be crystal clear.
