Hi Brendan

Yes unfortunately barley straw is like gold up here, it is grown in the eastern province and is only available from Servaas de Kok. I will look up his contact details or talk to him next week when I am in CapeTown, if you like.

At that price you might aswell get a UV light...Just my opinion.

Hi Brendan

3 Kg will go a long way I used it a while back for some string algae and have had no problems since, my Uv's are not switched on. This stuff is natural and works for a long period.

Hi,

Just browsing through this thread.

Some questions and some answers -

If algae in a pond is due to high levels of nitrates from over feeding where does the algae in a swimming pool come from when there are no fish and no feeding?

Does a UV light inhibit the growth of suspended single cell algae AND stringy algae on the walls or just the suspended single cell algae? IF a UV light can only affect the cells of algae passing through it - the suspended single cell algae - then a UV light is useless for the stringy algae.

A 3kg bag/bail of barley straw is a lot of barley straw and will last a koi keeper with a 20,000 litre pond about 2 years.

It how you use the barley straw that is important.

Barley straw releases an enzyme similar to hydrogen peroxide - i. e. a highly reactive molecule. Barley straw does not release hydrogen peroxide. This inhibits the growth of algae - it does not kill the algae like an algaecide will.

I have also thought about adding hydrogen peroxide in place of barley straw but I decided against it. Barley straw bio-degrades slowly and therefore adds this enzyme slowly and more importantly continuously to the pond water. Just adding a few ml of hydrogen peroxide will work for a very short time but then the algae just continues to grow. You need to attack it slowly and continuously to prevent it from growing.

I have also begun to suspect that once the fur like algae grows on the walls and floor of apopnd it too releases something into the water the inhibits the single cell algae that makes the pond water green or difficult to see through.

I recall many years ago the first manufacturere of UV lights in SA had them on his pond in Edenvale for a number of years. Once his pond had matured and the UV lights wore out he removed them and his water remained clear. At that time he asked that this not be mentioned! bom (I hope this is the right thingy)

Regards,
Chris

P.S. I am getting a whole lot up in about two weeks time - if any one wants some here in Gauteng let me know in the next day or two. Most of this is going towards a 250,000 litre water feature with koi and swans (and green water) also I need to top up and change my barley straw which has been in the pond for 4 months now.

Its time to get with the times people....barley straw Rolling Eyes Yes you can drive with a horse cart all the way from Joburg to Cape Town....or you can take your motor car or an air plane...It achieves the same goal, the one is just more convient and faster than the other.

If your pond is mature you dont need UVs - true....same said about Barley straw. Exclamation

What is easier than flipping a switch and see your problems dissappear? scratch My friend Eugen runs his UVs only at night and switch off in the day. You can switch your UVs off in winter aswell, they dont need to run 24/7 -they are only needed for when the green water arrives.

I must remember to build a barley straw chamber for my next koi pond, seems like its getting back into fashion. lol!

Hi Vossie -

We met at the Koi Farm - Koi Indaba last week end.

I can't believe how much you look like the picture you always attach to your postings .... amazing ...... Laughing

Will let you know when the barley straw arrives - it will be early in September.

Chris

Hi Guys,
I bought the straw and I had it in the pond for over a month now but he pond isn't getting any better.Maybe it is the way I put it it.
I tied an ancor to the bottom and a float to the top so it can stay just under the water level.Then I put it right under my water fall so that the water can flow through it.It is loosely packed in orrange bags. Must I give it more time to see what happens or what? Please I would appreciate your input.

Hi Brendan

It sounds like you have it right, the barley straw will eventually just about dissapate.

Do you perhaps notice a very slight yellow tint in your water, it should be and then you know it is there and working.

I really do not know why it is not working for you as for me it cleared my pond in 4 to 5 weeks.
Brendan I assume it is string algae you refer to, and you cannot see it going brown. The barley straw will not remove it it only stops it growing obviously it will eventually come loose and end up in the filter.

Give it a while longer these natural remedies does take its time.



Wayne

The problem is string algae does not go through your UV man so it cant get to it.

Thanks neville,
I did notice a light yellow tint in the water so I guess it is working. My problem is the small floating algae that is making my water green. I can't even see the bottom of my pond.But I will leave the straw to do it's thing and see what happens. Thanks for the reply.

Hi Brendan

Good,

let us know please.

A UV and good filtration should also take care of suspended algae, just be careful of the flow rate through the UV and use double what the recommendation is.

The algae problem can be prevented with use of good quality LED lights in the tank. The tank should be filtered on regularly basis. Powerhead should be used in the tank for better flow of water and avoid algae.
