So flow and water turn-over becomes a factor. So ammonia oxidation is easy to achieve while crystal clear water is difficult to achieve.įlow: The first two types of bacteria (the heterotrophic bacteria) can double in population every thirty minutes to an hour. It is also important to note that this same testing determined that ammonia oxidation only requires five square feet per pound of fish. For Healthy Fish and Crystal Clear Water Have 100 square Feet of Surface Area Minimum per Pound of Fish Surface Area: Elsewhere we determine experimentally that 100 square feet of surface area per pound of fish is required for crystal clear water. Crystal clear water in an aquarium Requirements for Crystal Clear Water This group of bacteria is the key to crystal clear water.įurther information on the topic of bacteria in the water column can be had by clicking the following link: 4.3. What is missed in aquarium hobby is the fact that the second type of bacteria, the biofilm heterotrophic bacteria, are also beneficial bacteria. These bacteria are what is normally called “beneficial bacteria”. The emphasis in filtration is generally on the third type of bacteria, the autotrophic bacteria. Surface biofilm and brown gunk bacteria that feed on oxygen, ammonia, nitrite and carbon dioxide (so called biofilm “autotrophic” bacteria).Surface biofilm and brown gunk bacteria that feed on dissolved organic material (so called biofilm and brown gunk “heterotrophic” bacteria).Floating bacteria that feed on dissolved organic material (so called water column “heterotrophic” bacteria).There are three types of bacteria in an aquarium: Bucchochromis Nototaeniaĭull water clarity is due mostly to floating bacteria and infusoria feeding on that bacteria. Since these organisms do not need a lot of food this requires VERY heavy water changes. The mechanism is that these water changes reduce the dissolved organic compounds in the water to the point where there is no food source for the organisms that cause cloudy water. The only way water changes can compensate for low biofiltration is if the water is changed on the order of 50% to 100% per day. Note that, contrary to popular myth, this does NOT mean water which has a 50% water change done to it once a week.
#Translucent aquarium fish free
The Key to Good Fish Health is Clean, Clear, Bacteria Free Water So fish in bacteria free water are far more healthy that fish in bacteria laden water. If the bacteria count in the water column is low the fish can put all their immune system resource towards keeping pathogens at bay. All owners of aquariums should strive for crystal-clear water. A high bacteria concentration will compromise the immune systems of the fish and can cause any number of disease and pathogen breakouts. So a lower bacterial count means more immune system resources available for fighting off pathogens. The fish’s immune system is constantly fighting all the bacteria that the gills are exposed to regardless of the type of bacteria. I would predict that the fish in this aquarium will be dying at a relatively high rate. good aeration) this aquarium might well have crystal clear water. Also note the lack of either air stone bubbles or “choppy waves” in the aquarium. The aquarium above is beautiful but note the ‘dull” water. The usual reason the water isn’t crystal-clear is because of heavy numbers of infusoria, algae, bacteria and protozoans. What is often missed in this discussion the importance of crystal-clear water. Most have water with a dull, semi-cloudy look. If you watch the aquarium YouTube or Facebook videos only roughly one in ten of the experienced aquarium owners have water that has that crystal-clear look to it. It is just something you know when you see it. But all experienced aquarium owners know what crystal-clear water is. Perfectly clear, indeed sparkling crystal-clear, water is the nirvana of any aquarium owner.
