I have a trickle waterfall which I run sometimes, but unfortunately the collecting basins are a bit leaky and I'm not sure how to make them watertight without polluting the water?

I love everything about my pond, there's always something interesting happening and always a bitto do clearing the blanket weed which is worse when the sun has warmed up the water. Do you use barley straw or use a special barley "chemical" ? Love exchanging ideas.

I use barley straw extract which is available at most aquatic centres and on the internet - I find it is very effective 

I bought a machine which is supposed to send microwaves or something to the wayer killing algae...waste money. I run my waterfall which has a uv light on it...that makes a wee difference, but I believe the best method is lots and lots of oxygenating plants. No chemicals though...definitely not!!

Barley straw extract is perfectly natural and is fine in wildlife ponds - it works well in ours while the oxygenating plants are getting going - it's only a month old.

That's looking brilliant Dovefromabove!

I spend so much time just sitting gazing into it - a great time waster

I bet!

Are your plants in planters? They are looking good I need my planters to be more disguised.

I've got a problem with blanket weed in my raised pond and cannot find anything to get rid of it. Tried the barley straw, didn't work. Have tried 2 different products ( sprinkle in the water type ) and neither has made any impact on its growth.

 

Some lovely ponds on here

Dove - your pond is looking really good and mature.  I love the reflection of your tree in the water.

My naughty shetland just finishing off the miniature bullrushes. I hope the dragonflies can find something else to climb up!

The first bud on the waterlily. I hope Robbie doesn't get a taste for them.

My Exmoor got into one of the ponds on the smallholding and ate almost all the bullrushes - it seemed to send him totally loopy for several hours

Try watercress Hartleyhare. Just buy a bag from the supermarket and chuck it in. It feeds on the nutrients that the weed likes. Easy to pull out if it gets a bit big.

Is your pond shallow? That can contribute as the water heats up  more quickly.

I better go and cheque on Robbie, Dove, but he's a bit loopy already. I once caught him standing  in a trailer so he could reach the leaves on an ash tree.

I think its around 18 inches - 2 feet. I did put watercress in it last summer but it didn't grow very well and then died off in autumn. I've lost all of my oxygenators, one of my marginal plants and most of my water soldiers, so clogged with weed I threw them away. I bought a miniature waterlily last year and that doesn't seem to be growing either. Even the mussels have blanket weed growing on them!

Mussels? Are you sure you've not put salt water into your pond?

We now have four fresh water mussels in our pond. Its rather fascinating watching them open!

Might give the straw extract a go...just for the start of spring time, or is that fighting against what natures intending....thoughts please. I mean nobody likes the algae apart from the creatures that need it and the plants that stop it growing.

I find the straw extract really good - totally wildlife friendly and helps create a healthy balance in the water - our pond was only dug this spring and already we have lots of wildlife living and breeding in there - if you scroll up to the pic of our pond you'll see

I went to the Garden Centre for more potting compost yesterday - I can't believe how much I get through! Whilst there I popped into the aquatic section and had a word with the pond specialist there. He assured me that if my (tiny...microscopic!) pond has clear water that is what is causing the red algae and the tiddly, wriggly worms (not too many of them). He said the clear water means I'm doing something right and that it sounds very healthy with an ideal balance of clear water and some red algae. The worms also indicate a very good mix and if any creatures do eventually move in they will be very happy.

Made me happy to hear all this anyway, so I am not worrying anymore about the algae.
