rED O Posted May 24, 2009 Report Share Posted May 24, 2009 Okay, tank is almost done now the sump. How do I calculate the size of input and output piping size I need. The sump is 70 gallons and the pump moves 2640 GPH. I think the inside dementions make it a 426 gallons of water, not tank size but water it will hold. Will this be enough filtration or will I need to keep some of my canister filters? Quote Link to comment Share on other sites More sharing options...

fish4fun Posted May 24, 2009 Report Share Posted May 24, 2009 (edited) ideally, you want your sump to be at least 1/3 the size of your tank. It is possible to get away with a sighhtly smaller sump. I have a 200 gal tank being filtereed by a 30 gal sump.....I do find that it is too small as I get micro bubbles in tank. a 70 gal sump may be too small Especially if your power turns off. i'd go with a 150 gal sump for safety.

Parachromis1 Posted May 24, 2009 Report Share Posted May 24, 2009 I would use 1" drains and a 3/4 return. Quote Link to comment Share on other sites More sharing options...
mikeymik'd Posted May 24, 2009 Report Share Posted May 24, 2009 1" flows 600 gph, way to small. You would need 2 x 1.5 for 2700gph. I would strongly recommend upgrading your sump size. 70 gal, probably running at half full only equals 35 gallons. Also you are gonna have issues with overflowing your sump when you lose power.

Drydock Posted May 25, 2009 Report Share Posted May 25, 2009 Dustin, I had to learn about my sump the trial and error way. If you want to come by look and ask questions some time, PM me and I'll give you the tour and answer what questions I can. Roger Quote Link to comment Share on other sites More sharing options...

boydo Posted May 25, 2009 Report Share Posted May 25, 2009 70 gal maybe a bit on the small side but will still work a 90 or 120 would be best. Dual pumps like mag drive 18's or 24's would get you decents circulation through 1" pipes each, and I alway perfer 2" returns. Use bio media like bio balls and ceramic rings, and fill that baby full. so remember that a 2640 gph pump with head and pipe loss with get you at the most 1700-1800 in the tank. I would keep the canisters too, circulating them in the sump not only will it help your tank, but in an emergency you could set up a tank or rubermaid for treatments using a canister trouble free. Also use GFCI breakers on your power supply alot cheaper than the alteritive. Best of Luck. Quote Link to comment Share on other sites More sharing options...
rED O Posted May 25, 2009 Author Report Share Posted May 25, 2009 I am not worried about it overflowing because my dad made a little thingy that has a sensor on it so when the water reaches the top of the sump, it will sense the water and he also got a solenoid valve that will snap shut if the water reaches that level. Its very handy and one of a kind :w00t: I need to sell two of the canisters, so I can only keep 2 out of the four. Quote Link to comment Share on other sites More sharing options...

If so, it won't help you when the power goes out. As has been stated, have a look in my post there is a link to a pipe sizing calculator. You plug in some numbers and it tells you how big the pipes need to be. Boom :boom: Quote Link to comment Share on other sites More sharing options...

But! also, when there is a power outage the solenoid valve closes when the power goes off. Quote Link to comment Share on other sites More sharing options...
