Review on ATLNM1 Nanomag Window Cleaning Device by Two Little Fishies by Maria Karkhanis

UPDATE Feb 2019. The second failed the same way. This is 2 of 3 and two different batches. Won't be using them again. If you use them, it's a good idea to test them for swelling and discard them before the red rust mix gets into your water. I really liked them but they CANNOT fail in a saltwater pool. UPDATE September 12, 2017 The backing has come loose from the portion of the magnetic cleaner that remains in the tank. The magnet RUSTED, 5 times thicker. So far no cattle have died, but the magnet looks really ugly. I have ordered a replacement (I still like the item) but will be keeping a close eye on it. I leave detergent in the tank 24/7. No problems yet, one is rusted. Not sure if we need to pull the cleaner out of the tank when not in use (which would be less helpful). ========================= = = ======================= ========= Bought a second one. The first is in a 10g nano and it worked so well I bought another to quench my 29g. It's a lot easier to use than the magnetic float I used. It goes around the corner perfectly so it can clean all sides. It's really very thin, allowing it to pass between pieces of jewelry without hitting them. One of the best aquarium gadgets I've ever bought. Highly recommended.
