hello still not used with the temperature that we have at the moment it is 8 at night in the ardennes. otherwise well received and in good condition works well.
very good product, easy to install but not yet had the opportunity to test its efficiency for lack of cold weather at the moment
Hello, we ordered two antifreeze bells for our tanks and I must say that we are extremely happy. The winter and the first frosts have arrived, and since I installed the bells "one in each basin", I am quiet because the water does not freeze any more. Small bubbles oxygen water, my small fish and aquatic plants will be better than last winter. I highly recommend this product.
Bell installed, the air kit works, but I can not give an opinion on its effectiveness because it has not yet made a big frost.
