Hello, I am intersted in getting a Tunze system going on my 190 gallon tank, but not sure what to get. The dimensions of my tank are 67" long X 24" wide X 27" deep. I currently have a 6" (all Southdown) deep sand bed with approx. 400 pounds of live rock. My tank is acrylic with a built on overflow box, and the water gets returned back to the tank about 1" below the water line. I hope to add 1 or 2 sea swirls to this return. I would greatly appreciate your advice on what model Tunze's I should get, and how many I will need. I am hoping I can accomplish this without creating a sand storm. Thank you very much in advance.
Mike
