twinkles Posted May 10, 2012 Report Share Posted May 10, 2012 We've got one of these sitting around.. Thanks to naughty puppies chewing the pool Anyway i've been wondering if I could use it as a filter for my new tank. Either to return the sump water to the tank or by putting media in it and using it the same as how it goes on the pool. Looks like any other external canister filter to me and it's never had any chemicals put through it. Nothing on it anywhere to say how many litres/hour, but it makes a good current in the 8ft/2500L pool so it can't be too shabby. Quote Link to comment Share on other sites More sharing options...
si_sphinx Posted May 10, 2012 Report Share Posted May 10, 2012 I used the exact same one on a gold fish pond as mechanical filtration before. Worked OK , needed cleaning a lot using the original filter cartridge. They do have a good output. I found out how much LPH it was once but have long forgotten now. It doesn't have a very good head height though. 600mm high? let me know if I am wrong. HTH Quote Link to comment Share on other sites More sharing options...
twinkles Posted May 10, 2012 Author Report Share Posted May 10, 2012 Excuse the silly question, but what's head height? The original filter cartridge is long gone but I figured I could just put some media in there.. Quote Link to comment Share on other sites More sharing options...
GrahamC Posted May 10, 2012 Report Share Posted May 10, 2012 How high it can effectively push the water above the pump. Quote Link to comment Share on other sites More sharing options...
Ira Posted May 10, 2012 Report Share Posted May 10, 2012 How high it can effectively push the water above the pump. Above the level of the source water. Pump location has no relevance to head height. If your intake is in the tank and the outlet is in the tank you have 0 head height. Quote Link to comment Share on other sites More sharing options...
twinkles Posted May 10, 2012 Author Report Share Posted May 10, 2012 Thanks If i remember correctly when it was on the pool the intake was two holes halfway down the side, and the outlet was slightly higher, all below the waterline. So if I was to put the filter under the tank, with intake and outlet at the same level near the top of the tank under the water line, i'd get about the same flow rate? But if the outlet from the filter was above the intake and water line then it would slow down the flow? Quote Link to comment Share on other sites More sharing options...

I was thinking of pumps used in fountains and aquaponics where the water level and pump level are the same. Quote Link to comment Share on other sites More sharing options...

But if the outlet from the filter was above the intake and water line then it would slow down the flow? At the risk of getting this wrong, I would say it's the difference between the top of the water line and where your water outlet exits, and that pump has to overcome this gravitational difference.

twinkles Posted May 10, 2012 Author Report Share Posted May 10, 2012 Thanks I can picture how it works now. I'm just planning what to do for filtering and layout on a new tank, managed to grab a nice big new home for the natives I might try running the pool filter with the intake on the left side and out on the right just below the waterline, with some media in it, to do some of the filtering and create a good flow. Then put my existing diy powerhead filter at the bottom of the left side also, and the outtake above the water on the right so it trickles back in through the plants like it does now.
