Filter cotton for nitrifying bacteria, is it good or something else?
At the end of the filter to meet two conditions: 1, debris filter. 2. Culture of nitrobacteria. The first consideration must be placed in several layers of the upper groove surface filter. This is easy to take out and wash. The culture cycle of nitrifying bacteria is very slow, and the attachments should not be disturbed frequently. So late basically do not move. The growth environment of nitrifying bacteria is porous material, avoiding light. These two conditions meet the need for self - growth of nitrobacteria. I've done all kinds of biochemical cotton, glass change, magnetic ring and so on. Later in the field of fish farming people see dragon fish, very simple filter (of course, do not rule out the good filter effect), the effect is the same very good water permeability.
If you release the feed, you need about 150 grams of homemade burgers a day. The metabolites can be basically filtered and decomposed by nitrifying bacteria. If there is one more turtle, the amount of nitrifying bacteria is obviously not enough to break down the residual organic matter in the water. Water quality began to decrease. In the early days of fish culture, a great deal of time and money was spent, and later it was found that the most important thing was to observe others and analyze them in a scientific way. The result is super simple. Before the bottom filter into the various filter material very much, is also very good, but when a new fish tank, the tank is easy to outbreak of a large area of diseases and parasites, it found more kinds of new media is a very troublesome thing. Because as long as there is water, there will be diseases and eggs. Talk about my own feeding experience, Louzhu can refer to, less detours.
Now I first placed upper 6 layers of filter cotton, mainly used to filter water objects, convenient cleaning. The use of thick black sponge, second still placed thick black sponge, usually placed third lattice water pump, no waste, the thick black sponge cut into 2 cm *2 cm in the box, the greatest degree of nitrifying bacteria attached to create space. Water quality is good, only cleaning cotton filter for 3 years now. Change 1/4 water a week, 380 kg water tank, 120 kg water filter, replaced a pump during the period. This environment is the biggest stocking, a silver dragon (40 cm long), a lucky (35 cm long), a pig nosed turtle (25 cm long).
