    Yes its something we all get from time to time, its String Algae, at this time of year what I do is to remove as much as I can manually with a pool brush or net, its not really the time of year to start treatments as the recommendation is that treatments should be done above 10 degrees water temperature, it can be caused by an excess of nutrients in the pond or if the pond is in direct sunlight, what are your water parameters, I think nitrate feeds algae, a good UV would also be beneficial, the UV lamp should be replaced every year

    Thanks buddy, that I thought it was but didn’t want to name it and put a seed in the thoughts of others. I have been removing with a pool brush but wondered if there was anything more I could do to prevent?

    the sun rises over the pond so it gets about 4hrs of morning sun everyday.
    Parameters seemed good but will do some more checks. Yea I have a fairly good uv and if anything went over the top as in my eyes you can’t have too much uv.

    aquasource blanket weed resolve works at lower temps and does a great job,careful twiddling with a stick or breaking it off as when you do it realses more to grow,better just treating it,andi

    I’ve got similar happening in my pond at the mo. I tried Resolve and it knocked it back for sure but this stuff below I’m adding every day 10days and after 2 doses so far the weed is breaking down visibly and the filters are clearing it up.

    Stop Blanketweed 2.5kg https://www.amazon.co.uk/dp/B005H70R..._834ECb3K4801N

    Both clearly work but for me personally this seems like it’s maybe a little more effective.

    If you've not got any plants in your pond, you can put into the water 0.3% of Pure Dried Vacuum Salt. That will kill it dead for you. If you have then Resolve would be the product I would recommend.

    I tried salt in my old pond, never did a thing for the blanket weed, everyone seemed to think it would work but it didn't work for me

    The chances are you've not put enough in then. I had to take the salt level to 0.5% last year in a customers pond to kill the Blanketweed. 9 times out of 10 0.3% does the job. If you're going to go down the salt road, pick yourself up a salinity meter then you know exactly how much salt is in your pond. If there's no plants in a Koi pond, I'll always use salt first. If there is, Resolve goes in Algae treatment

    Quite possibly, I just threw in 3 mug fulls lol, it was a few years ago and I didn't know what size the pond was at the time, i rubbed it into the algae on the sides as instructed by my local shop, anyway I ended up paying nearly £50 for some treatment, although it lasted a few years

    Cheers for this info Mythril. I’ve got a 3,850 gallon pond and I’m battling with string algae at the mo. I’m keeping on top of it, just, but was wondering about salting to see off the residual.

    I don’t have plants at the moment, some arriving later this month, so would you suggest salting to kill it all off beforehand and then water changes to bring the salinity back down prior to dropping the plants in? Thanks.

    If you've no plants in, salt it ! Start at 0.3% and give it a week. If it's still not looking like it's starting to die, up the salinity levels a touch. Say to 0.5%. That will 100% kill it dead in a fairly short space of time. Just get ready for your filters to block up. Luckily the ponds I work on all have drums so it's not too bad. Once it's all gone, start with the water changes. It'll take a while to remove all of the salt though.

    Now I've absolutely no evidence for this next bit but it's the only thing I've changed in my routine for my pond so I'm putting it down to that. I use to really struggle with Blanketweed and found treatments like Pink Crystals would hike up my PH levels to unacceptable levels and I couldn't bring them down no matter how much fresh water I flushed though. So I would jet wash the pond and refill it and my water parameters would all be spot on again. What's changed ? Well I've been adding once a week about 100g of Montmorillonite Clay to my pond and I've not had any Blanketweed for well over 1.5 years now.

    You can do a little experiment if you wish. Put some clay that you've not mixed up into your pond on top of the Blanketweed and it will kill that area it touches. PP does the same also funnily enough.

    Once you've killed the Blanketweed with salt, get yourself some clay and see if it works for you. Like I said, I've no proof it works, only that it kills it dead if you put a clump on an area but if you're adding X amount per week, I think it keeps on to of it and it doesn't return. Hope this helps.

    Cheers for the info - I'll give the salt a go then before the plants pitch up.

    I've sorted some Pure Dried Vacuum Salt as you mentioned so I am all good there but what salinity tester do you recommend? I can see some for £20 and some for £120 and everything in between. Hmmm...

    P.s. that is very curious about the clay. I'll get rid of the weed with salt (hopefully) and see if it comes back when flushed out and the plants are in, If it does then I'll give the clay a try!

    I have one of these: Koi Medic Salt Meter

    Their not cheap but it's still going strong.

    The idea is to add the clay once the Blanketweed has died off with the salt. Prevention is better than a cure as they say.

    Managed last year to drop some blanket weed when cleaning the waste shute on the Draco, and it fell in the the bio section of the Nexus. This year it has comeback with a vengeance and was actually blocking the return to pond of the Nexus, no point in using normal blanket weed treatments, they only loosen it in the pond and dump it in the filter, so isolated the Nexus for thirty six hours and put a heavy dose of salt in it, result now after two weeks is no blanket weed blocking the return. No trace of it whatsoever.

    Glad you got that sorted!

    My Nexus is dealing with the dying algae really well.
    Although I have doubled the amount of media in the easy section so it has no chance of getting through to the outer chamber and beyond.

    I had to clean it every few days as it was clogging the outer wall of the easy but that was a simple task.

    Now I’m back to normal cleaning and just topping up on Resolve if needed.

    Cheers Fred. To be fair, your pointer to use Resolve has been a massive help. Seems to be clearing it well Algae treatment
