What makes a fish tank stink? An aquarium that smells bad is not healthy. A stinky tank is a dying tank. An aquarium will die when it is not able to maintain the life of its aquarium plants and animals in it. So what kills aquariums. There are 2 primary causes. Both are a result of bad advice. The first cause of stinky tank is excess food. Even if all the food is eaten by the aquarium fish, they may create more waste than the biological activity in the tank is able to covert to energy. Waste that is not converted to energy rots and stinks. The main cause of inadequate biological activity is chemical treatment of the tank. Father Fish believes there are no chemicals that are critical for the health of an aquarium. Most chemicals are dosed in the tank to kill something. This creates death. Death is the opposite of life. Killing living organisms is not an appropriate method to maintain a healthy, living aquarium. Build a dirted deep substrate according to Father Fish instructions found in the Father Fish Shoal. Create a good web using Father Fish's techniques. Feed less than daily high quality foods in very small amounts. These procedures, followed carefully will mean your tank will be sweet smelling and thriving with life. and never, never stink. #fatherfish #aquarium #fatherfishaquarium #fatherfishpodcast #deepsubstrate #fishtank #aquariumplants #fishaquarium #podcast #aquariumfish #walstad #fishtube 00:00 Introduction 00:35 Causes of a stinky tank 02:00 What a stinky tank means 02:42 Father Fish's tanks 04:00 When chemicals are added 11:03 Chemicals and Natural Aquariums 13:00 It's that simple
