Up for sale is my Cetus Sieve Mark II that is gravity fed. I have used it for about 2 years and it works great.
It has always been set up indoors on my 2000 gallon aquarium setup. I had a custom lexan top made for it to keep the noise down. It comes with the factory 300 micron screen. I also have a sequence pump that works well with this filter and a 200 micron screen available in separate listings.The item "Cetus Sieve Mark II Pond Filter Aquarium" is in sale since Saturday, July 7, 2018.
