A good rule to follow to understand if an internal filter is of the right size for your tank is to choose a filter almost as big as the smaller lateral glass of the aquarium. an undersized filter can not guarantee constant chemical values, even if it can clean water, great sudden changes of nitrite, nitrate, and ammonia due to the small concentration of filtering bacteria, can kill your fish and plants.
