Magic - This little filter has saved the day, i have a new aquarium set up, and used all the tap safe and filter aid products and let the filter run for 2 days before getting the fish, after 2 days my water was going milky, the soultions i added were just creating a milky film and not being mixed by the filter, infact i very much doubt the new filter was working at all. I got this to assist my existing filter, it arrived today just intime, as i couldnt see through my tank as you can see in the 1st picture, i instantly set the filter up, it took less than 1 min to attach it to my air pump and plonk it in the tank -pic 2, to my utter amazement, 5 hours later my water is almost crystal clear -pic 3, and the fish are now swimming about and playing happily in crystal clear water.
