How to clean the acrylic fish tank, the usual acrylic fish tank internal filtration system includes the following components: filter cotton, biochemical cotton, glass ring (mainly including ceramic ring and biological stone) and activated carbon (ammonia stone, medical stone, etc.). It can be seen from these basic accessories that a complete filter system is relatively complicated for sealing and installation performance. The key point is that multiple cleanings are not conducive to protecting the nitrifying bacteria inside the cleaning system. Because the main water quality cleaning work needs their help to complete. When we choose acrylic fish tank water quality cleaning filter materials, we must choose products of high quality and relatively high prices. Let’s talk briefly about the cleaning of the internal filter cotton of the acrylic fish tank. Pay attention to the frequency, try to clean it thoroughly once, and avoid multiple cleanings that destroy nitrifying bacteria. The main thing we usually do is physical filtration. Specifically, we are mainly responsible for the cleaning of large solid residues, so the filter cotton is particularly easy to get dirty. Generally take advantage of the opportunity to change the water, remove the filter cotton, and rinse repeatedly. Note: Do not scrub repeatedly during the washing process; do not use the tap to wash directly, which will destroy the nitrifying bacteria and cause the loss of biological filtration.
