I wish I could take a before and after photo. I installed the sponge filter about 2 hours ago. For several months he worked on a small HOB that worked well. But in a short time after installing the sponge filter, the water became so crystal clear that it makes a noticeable difference. From now on all my aquariums will definitely be equipped with sponge filters. Sometimes it's just better.
