What is the difference between algae and Chara and how should I treat them?
Veronica – Savannah, GA
To an entomologist, the differences between a cockroach and a termite may be a subject of profound fascination. However, to a homeowner, they’re both insect problems. If you have them, you sure as heck want to get rid of them – and the sooner the better.
Likewise, when the seasoned water biologist sees filamentous algae floating on the surface of a pond, he can probably identify the strain — Spirogyra, Oscillatoria, Pithophora, Anabaena or perhaps some combination thereof. Just beneath the surface, he might point out the gray-green, cylindrical branches of Chara, another form of algae that is often mistaken for a submerged flowering plant, except it has no flower and no defined root system.
Most of you would probably find this at least mildly interesting, unless, of course, the biologist is talking about your pond. Where he sees variations of filamentous algae, you see ‘pond scum’:what he identifies as Chara, you know as ‘skunkweed’ or ‘muskgrass.’ Suddenly, what it is, matters a whole lot less to you than how to get rid of it.
Well, fortunately, we’ve got some great options for you. One gallon of Algae Defense, mixed with water and Cide-Kick, can treat up to 8,000 square feet of pond surface. It’s best applied with an Airmax Pond Sprayer. It should come as no surprise that the sooner you address an algae issue with Algae Defense, the quicker and more effective the results. Algae Defense is best used to eliminate algae on or just below the surface of your pond. For bottom forming algae, like Chara, we suggest Cutrine Granular – 12 pounds can treat 8,700 square feet.
If you find that the algae in your pond has graduated from ‘issue’ to ‘problem,’ you may find that multiple applications of Algae Defense and Cutrine Granular are necessary. Make sure you treat your pond in small sections waiting a week between treatments, and have sufficient aeration when treating during the hot summer months. We also recommend following up treatments with the use of PondLogic PondClear and PondLogic MuckAway, which use environmentally friendly bacteria to break down the dead algae.
When it comes to the health of your pond, knowing what goes on is important, but knowing how to deal with it is essential.
