String Algae, Blanketweed, Filamentous Algae

More talk about string algae:

A solution to it, if it's a problem for you.
To get rid of string algae or blanketweed, add about 1 quart of hydrogen peroxide per 1000 gallons of water.  When the algae grows, clean out as much as you can and just pour the peroxide in.  It gets rid of all of the algae.

Is the string algae a bad thing or just some people don't like it. We have it growing on our lilies and it doesn't bother us.

It's an OK thing. It keeps the pond clean and clear. Fish love to eat it, but can't stay ahead of it. I never mind it, but most folks simply can't bear it. I get more letters about blanketweed/string algae than anything else.

Wow I kinda like it lol. Blanketweed is that the algae on the bottom attached to the liner?

Pondlady again:  
Blanketweed is the stuff that looks like angel hair spaghetti. You can get it out of the pond with a spaghetti fork if you wish.

The conversation continues:  
Thats funny, I think I know what you're talking about it was on the waterfall awhile back, whole thing gets covered in algae and one good rain storm its all gone.

Another answer:  
All ponds should have a nice blanket of algae along the sides of the pond that should be about 1/4" to 1/2". At least, that's what mine are like although one pond has no algae along the sides that I can see. I wonder if this has anything to do with the alkalinity of the water.

Pondlady again:  
Algae on the sides of the pond can only help with pH. If a pond is balanced properly, a healthy pH of about 7 happens automatically.

You can learn all about algae, blanketweed or just plain pond scum in my book, "A Practical Guide to Building and Maintaining your Pond", available here.
