What is the green stuff growing on the rocks of my pond’s waterfall?
I рlасе a pond іn mу back yard a small over a month ago, аnd even аѕ thе water remains crystal clear, thе rocks іn thе waterfall аrе turning green аnd fuzzy. I’ve searched many sites, bυt I саn’t seem tο pinpoint thе type οf algae, οr even іf іt IS algae! Mу fish аrе рlеаѕеd аnd healthy. Thе waterfall looks horrible. Please hеlр!
it can possibly be moss it is fuzzy and green http://www.coolantarctica.com/gallery2/plants/images/plants_1000_moss.jpg / http://static.howstuffworks.com/gif/irish-moss-1.jpg / moss can look diffrent ways .
Yes, your right ,it’s algae.When the weather gets colder it will die off. You can also buy a product called pond block or any type of algae control product that is not harmful to fish. I have a UV light and still get that on the waterfall. I have also seen ponds with moss growing on the rocks of waterfalls ,but it would be to soon for that with your pond.
It is probably thread algae.
Pulling the Strings from Algae
There are several kinds that fall into one or two categories. Algae Bloom is “green water” and Thread Algae is algae that you can really touch. You can’t get rid of both the same way.
Thread algae is the algae that hangs from rocks in the waterfall, attaches to plants or simply hangs on the surface of the water (then called Blanket Algae). Do not confuse thread algae with the soft, velvety, jelly-like coating that forms on the sides of the pond. This is excellent algae. The fish like to eat it and it contains beneficial bacteria. When your pond has this kind of algae, generally, it is balanced.
You can kill what’s there with a product called AlgaeFix. When the algae income in about a week go to plot ” B “. Open the link below and read it all.
That’s when barley comes into the picture – in the form or barley bales or barley extract. Basically, barley emits natural enzymes that thwarts the growth of thread algae. Although the directions will say that you can simply throw the bales into the pond we’ve found that it’s more effective if placed where the pond water will run through it and distribute this bacteria. Barley extract is more expensive but simpler to use and quicker.

It is thread algae, and if you have it just growing on your waterfall, you can pull it off every few days, brush or scrape the rocks and it will look fine.
Even with clean, clear water, you may get algae on the rocks as the water evaporates there, and any nitrogen in the water is concentrated, selection the algae to grow. Using chemicals or UV lights will probably not cure the thread algae on waterfalls. You can always stop feeding your fish – it won’t harm them and it will reduce the amount of nitrogen in the water.
It is habitual. It is probably hair algae. Nothing incorrect with it and it is really healthy as long as it does not take over. You might have more problems with pond scum algae or water algae but since your water is clear dont worry.
