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.
product compliant with the camera in use at the moment works fine I put the note of 4 because for the moment not had a strong frost basin slightly covered with ice but it is visible the bell does its job to do with jelly strong
Very good product value for money and very effective since its assembly three weeks ago
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.
Product corresponds to the order. Not yet put into operation. Quick delivery
I have not yet tested this device, I installed it and I did a test, everything looks conclusive
product received quickly but not yet used we will see this winter with the gel
Apparently good product, but a bit early to test it. Winter is not here yet.
I have received the product, however it lacks the diffuser so it's clear that I have no micro bubbles
Works very well, even with -15 ° C for a month. Very affordable price. I strongly advise
Tested in January 2016 in strong frost, simple and very effective device: air is sent under the bell via an electric bubbler, the pool is oxygenated and it does not freeze at the bell. The bubbler, against all odds, is very effective (for a set at 15 euros all!): It is sold with a replacement membrane, air stone and tube 7 meters in length (color green fluo-blur color) the device consumes very little. So, I'll remove the polystyrene during the warm and keep the bubbler running all year round.
I can not say much except that the product looks serious, without reproach. superb
