String Algae in Summer

Prevention is Key!

String algae can be a real pest. It's most often trouble in late winter or early spring and when it really starts to heat up in the summer. We've noticed it is starting to grow like crazy here at the store and at our homes.


The photo above is not current, this is usually what it looks like in the spring but it can still get bad in summer too. Have no fear...it's not unhealthy for your pond, but it's not pretty -- that's for sure! So let's talk about preventing it first, then treating it.

Prevention

  • In the pond, it's easy to prevent. We keep lots of aquatic plants in our ponds and use Clarity Max every week. The combination of the two keep algae in the pond in check with very little issues. You may have to use more Clarity Max when the water temps rise, but the algae in your pond will not become any more than a slight covering --- which is good.
  • Creeks and waterfalls are a little more tricky. Because they are highly oxygenated, string algae will grow there first. Clarity Max will work on creeks and waterfalls somewhat, but not completely. In these areas, there most likely will be some treating and removing.
Treatment
  • Clarity Max will work as a treatment to remove string algae as well, but if there are long strands, try to pull those out by hand first. You can treat up to every 3 days, but be ready to clean your filters as the algae dislodges. 
  • On waterfalls and creeks pull out as much as possible by hand as well. Then use Algae Off to treat.
  • Be sure to use Biological Clarifier weekly also to break down the algae as it's dislodged from your pond. If you don't, that algae will decompose and create more algae!

Remember this.. It's important to starve the algae. By providing less nutrients (fish waste, uneaten fish food, leaves, decaying plant materials, etc.) for algae, algae will grow less. You can also starve algae by adding more aquatic plants to compete with algae.

We're here to help if you have other questions about algae or other pond issues!
