Also, you must understand that there two types of plants: 1. water column feeders (absorb nutrients primarily through their leaves) Denitrators have particles that promote the activeness of microorganisms, which feed on nitrate and break it down biologically. It seems like the main problem is that these nitrate-reducing pads usually do not have any instruction on how to use them. Contrary to popular belief, a level of 20 ppm of nitrate could become toxic to freshwater fish and invertebrates over time. API master kit (link to check the price on Amazon), Read more about it in my article “Advanced Guide to Planted Tank Lighting”. When there’s a high accumulation of nitrate in the aquarium it’s important to react fast as fish mortalities could soon take place. Another source of waste is the uneaten food particles that slowly decompose on the tank’s bottom. Another option is to have a special filter with nitrate-reducing media. In the aquarium hobby, there is a popular idea that nitrogen in the shape of nitrate is one of the most important nutrients for aquatic plants. I also backed off my ammonia dosing a bit so I since my ammonia was converting to nitrite very quickly. Take the bottle “Nitrates”. High Nitrite/Nitrate Levels in Planted Tank!

Big water changes are often the reason for the “, Unlike shrimp, most species of fish can eventually acclimate to high nitrates. Fin Frequent water changes alter the parameters and make the shrimp undergo a forced molt. Fish that constantly live in water with high levels of nitrates do not live as long. This method is for people who are willing to occasionally reload on inexpensive supplies. The rate of conversion depends on the size of the bacterial colony. In order to realize photosynthesis, aquatic plants require the necessary quantities of nutrients in the water. When there are only 1 to 2 aquatic plants and you forget to prune them regularly the decaying plant matter will outweigh the benefits of the nitrate consumption. This, in turn, provides indirect benefits to the fish, as the lower levels reduce osmotic stress, while the plants provide hideouts.
