Green water & algae #1
Hi

I've noticed that the water in my pond has become very green with a scum on the surface and there is string-like algae covering the liner and plants.

I am very concerned about this and don't want it to affect my fish.

I have tried to oxygenate the pond with an airstone....

Will I need to empty the pond and refill?....

...or is there a treatment available?...

My pond is around 6 feet by 9 feet and 3 feet deep.

Any comments will be much appreciated.

Thanks

Steve

Re: Green water & algae #2
I'm in no way, shape or form an expert on ponds but isn't barley straw meant to help with this? You get little bales and float them in the water.

Do you know what your readings are for nitrate and phosphate? That might help find the root cause of the algae

Thanks for the reply Suey..

I'll take some readings to check those levels.

I've heard of the barley straw but I thought that was to get rid of the blanket weed......the floating stuff.

This looks to have a brownish tinge and is growing on everything.

Many thanks

Steve

Re: Green water & algae #4
Hi, had this problem ealier this year cos I installed a heater which -of course- encouraged all sorts of green stuff, go to a local pond or koi specialist shop there are dozens of treatments for all sorts of algae problems some of them colour the water for a few days but they do work as long as you get the dosage right, it worked for mine spectacularly. Hope this helpsalgae

I have to ask (Because you don't mention it) Have you not got a UV and biological filter?

The string like stuff is called string algae, there are various cures available the best one is a stck to remove it with, since what cure works for some one else may not work for you, but a stick works for everyone.

Re: Green water & algae #7
Hi guy?s,

Can I just add to the removal of the string algae with a stick, just wind the algae around the stick to remove it from the water then leave the algae at the side of the pond to allow any creatures caught up in the algae to return to the water..if that makes sense
