The finished tank with lid is very attractive at first glance. It has filtration, oxygenation, and lights. However, it is often difficult to raise fish in such a tank because the filtration system is too useless.
The main problem with the finished tank with lid is that the filter box is too shallow, cannot store water inside, and can barely fit the filter material, which results in a very weak biochemical filtration. Without sufficient biochemical filtration and sufficient nitrifying bacteria cannot be cultivated, a stable and effective nitrification system cannot be formed, and good water quality cannot be maintained.
