Blanket Weed Problems .. Have you checked ?

1. Is the ph of the water close to neutral? If not investigate possible cause of alkalinity.
2. Is the pool free of rotting vegetation ( I know this is the hard bit ...gardening with wellies ).
3. Check that nutrients are not entering the pool via runoff from the surrounding area.
4. Are domestic animals and wildlife ( ducks, geese etc) using the pool excessively?
5. Are the plants within the pool suited to their environment? Have their numbers been drastically reduced by what has been a hard winter?
6. Are the plants in your pool good filter feeders?
7. Bubbles floating on the pools surface can indicate excessive nutrient levels.

Ecotreat Clarity Pro

As I mentioned earlier Chris has found that clarity Pro has performed well in his pool and we have been sufficiently encouraged to stock this product. How does it work? Clarity Pro is a bacterial additive that biologically converts the components which string algae/blanket weed require in order to thrive and therefore work in a similar fashion to the naturally occuring cultures on the substrate filter and maybe thought of as a pedigree version of bacteria which which we believe would be unlikely to colonise our pools by natural means. Anyone requiring Clarity Pro can contact us on the usual numbers or via the website

The Scurge of pools..BLANKET WEED

My pool plants do not want to grow, a combination of cold nights and winds is enough to make them uproot and leave for a life of easy growing in a nice warm pool!
I have been receiving inquiries concerning string algae/blanket weed via the phone and blog.
We are used to having string algae during the spring months but this year it has been particularly prevalent. The problem is almost certainly brought about by an awakening of the substrate filter as it begins to process the early algal blooms and the build up of matter from the previous season. With the lengthening days this process will kick off in relatively low water temperatures, the plants within the pool will however require higher water temperatures and a good dose of sunshine to grow effectively. We therefore have a situation .... the plants fuel (nitrate) is building up in the water whilst the plants are unable to extract this nutrient. String algae/blanket weed will proliferate in these conditions especially in oxygen rich water.
Hopefully the warmer weather will soon help, mother nature always manages to put us in our place!
Some of you ( thanks for comments on the blog ) are wondering whether there are any out of the bottle remedies, we generally find such intervention unnecessary.... nature and a bit of
algae grabbing usually works. Our colleague Chris has had relatively good results with Ecotreat.

The Scurge of pools..BLANKET WEED

We have been having a few calls from people concerning blanket weed problems as well as a couple of comments on this blog. I will be in the office at the weekend and will explain why this has been a particular problem this year.
