View Full Version : Sizing Central Filtration?

10-07-2002, 11:19 AM
Ok guys, I plan on putting in a central filtation system in my fishroom, and the question is "are there any guides for propre sizing?" I would assume that I would want twice the volume of what could drain from the tanks. So if I put 2 x 65, 1 x 40, 1 x 45, 1 x 35, and 1 x 30 all on the same system... and assume that I set-up my overflow boxes so that a max of 5 gallons can come out of any of the tanks... that would make 30 gallons, and double would be 60. So if I had 60 gallons of capacity I would be ok. Now for flow I want 4-5 times the total volume filtered per hour, thus a pump that After head loses would pump between 1120 and 1400 gph. Does this make sense? Am I way over doing it? Any advice would be greatly appreciated.

The math all sounds about right. the rule of thumb for cichlid filtration is 10 times an hour, but....

The Mag Drive 1800 will do about 1200 g.p.h. with 6 ft. of head. I am looking at getting two for my system. I got a price of 195.00 for 2 of them from a local guy. www.kenmenard.net I think you have to email for a price, not listed on the site. Great prices of fish food too!!!

What are you planning on for heating the system? Are you gonna use a temp. controller? I would suggest looking at the article AND the product at www.jehmco.com/PRODUCTS_/HARDWARE_/Temperature_Controller/temperature_controller.html I got one and it is great!
