Hydra Crystal Treats UpTo 10,000 litres + Pond Algae Green Water Remover 1Kg

We have a natural pond and suddenly bryopsis algae appeared. We were worried that this product wouldn’t work but thankfully it did. It’s started to work instantly and the following morning we began scooping out the floating debris off the water’s surface. We continued to do this each day after. Very affordable and safe for fish and wildlife too. Highly recommend.

Very good to clear water. Then comes the work clearing the dead stuff. Well worth trying, but if your pond was dirty like mine then the work begins. But it does the job very well

Kills algae for real ! Filters will need cleaning every day because it really clumps the algae and fills the filter quickly.

It seems to have taken me ages but I finally appear to have achieved the right “balance” within my modest pond (say 3m diameter, round). I have bought:https://www.amazon.co.uk/gp/product/B004V7JJEQ/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B003GV6T9G/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00JXNEIDA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00G96XHXQ/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00VLX203A/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00I4278K6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B0077L4V8C/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00DJ1T4L8/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00LW0RD0M/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1https://www.amazon.co.uk/gp/product/B00SYS5GJ0/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1Which, to say the least, ought to keep my little pond running at perfect levels !I should also add that when we moved into the house, the pond already had a weak filter / fountain system. I’ve since re-attached that to the pond-spitters (the fairy and the cherub). When attached to the more powerful filtration systems it was like a garden sprinkler !Of all of this ‘kit’ the anti-blanket weed treatment has proved excellent – no signs of it 1 week after application.Without a doubt the main thing is the flitration system. However, I think that is closely followed by the air pump + air stones.I’ve obviously had to use a system of gravel / Cotswold stone to hide the pumps and lines. I now have beautifully clear water, cascading off stones into the pond. I have 30 + fish in the pond and since I’ve got the balance right, no fatalities.I also bought this, which was a disaster:https://www.amazon.co.uk/gp/product/B004R39F34/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1Basically the effect was to create ‘spiders web’ which algae could cling to at the surface of the pond. Although the water underneath was perfectly clear the anti-heron mesh ruined visibility….hence I replaced it with the galvanised mesh listed above which hangs 1 inch above the water and so doesn’t create a gudge-trap.OK: I think I may have gone wild on buying kit for the pond, but finally I’ve got rid of the niggles and have achieved a perfectly good biological balance…..Good luck fellow pondies !

I bought 2kg of this product and I did everything it said but it didn’t clear my pond. I wouldn’t buy this product to clear your pond.

Does not work and leaves an awful scum in my plastic pool. Yes I did follow the instructions.

This is the best solution,if you want your pond crystal clear,I have put four photos on,over 4 days from green water to crystal clear,my pond is not the biggest 6x4x2 ft,I put three lots of of 30 ml spoons each day for 4 days,and I got crystal clear water on the 5th,I have tried a few of these green water solutions, but this is the best I have used.

Having received the crystals and reading the instructions I followed them to the letter. the only problem I had was that I couldn't work out how much to put in. I rang the company and a very nice lady went through the measurements with me and told me how much to use. she also went through the everything that I should do first. test the water. change 10% to 20% of the water. clean out filter and put fresh filters in. do the glass test. make sure there was enough air in the pond via air rocks etc. KNOW I HAVE A CRYSTAL CLEAR POND. AMAZEING!!!!!!!!. the only thing I did add the next day was a filter blanket to take away the fine sediment as my filters wasn't enough.
