Lehaut Posted January 24, 2014 Share Posted January 24, 2014 Is this some type of internet bot/crawler.I ask because out of interest I Googled the posters name, its all over the net! Link to comment Share on other sites More sharing options...
osie Posted January 25, 2014 Share Posted January 25, 2014 It might be one of those new types of bots that knows about nitrate, phoshate and dissolved oxygen levels... ;-) Link to comment Share on other sites More sharing options...

Théière Posted January 27, 2014 Share Posted January 27, 2014 Ok Loghutemina,Algae grows because of light and nutrients, you need a pond test kit to test for phosphates, nitrates and nitrites, oxygen saturation level and ammonia (very dangerous to your fish) You have no plants and some plants will lower your nitrate/nitrite and ammonia levels and create areas of shade for the fish and areas where algae doesn't grow. If the water is nutrient rich and you only run the pump for a few hours over night then you are not doing enough hours for all of the water to pass through the little UV chamber to be treated. If the algae is in the form of blanket weed then you need to remove that manually with a net as it won't ever go through the UV chamber so it will just keep multiplying. Most of all, is the UV lamp working? These do fail and need replacement. Your Bioforce filter/UV is almost at maximum for the size of your pond and doesn't filter fine enough to remove a lot of the particles and the biological filtration works better in summer than this time of year. If your pump can handle it I would suggest a zeolite filter be added to your setup, this will remove the ammonia and filter out far more at this time of year than a biological filter. What is the water temperature?Do you have an air stone to introduce oxygen into the water/filter? Biological filters won't work without oxygen so cannot process nitrates/ nitrites and ammonia In any event, run your pump for a lot longer and during the day, most Koi people run 24/7 Link to comment Share on other sites More sharing options...

Théière Posted January 29, 2014 Share Posted January 29, 2014 Hmm, the world always wants instant this and that, started with instant coffee, horrible stuff.If you want instant, then remove your fish to an isolation tank and add 500 ml of 9.6% brico bleach and don't run the pump just stir by hand. Down at the pet shop/fish and pond dealers get some dechlorinator (sodium thiosulphate) and once the algae is dead treat the water to dechlorinate and adjust the pHAdding a weak copper algaecide will also help. Barley straw is too slow and is only a slow release of hydrogen peroxide anyway and you can dose that in small amounts without affecting the fish, it's hair bleach, not chlorine bleach.

loghutemina Posted February 11, 2014 Author Share Posted February 11, 2014 Thanks for your replies and support me....I have changed my pond's water and enter a fresh water into it and i am taking care of my pond in natural ways by regularly pumping it and covered it from top to trap the sunlight...
