Serenity Aquatics Biochemical Sponge Filter

I like it it

I purchased the filter to used in an emergency hospital tank keeing the sponge in my sump (for good bacteria)
However i ended up with a large goldfish bowl so i placed spider wood gravel and plants in the bowl.
To keep the water looking crystle clear i placed the air filter in behind the spider wood
Pretty cool very happy

Great filter.. looks nice in aquarium and does an excellent job.. would buy again.
