nw1411 Posted February 14, 2005 Share Posted February 14, 2005 Can anyone shed any light on what LPH a canister filter should be running for a 36x14x20 (165L) ? Cheers Nath Link to comment Share on other sites More sharing options...
Ant Posted February 14, 2005 Share Posted February 14, 2005 should be filtering the volume at least 4 x an hour. So a cannister filter doing 800 lph should more than suffice or you could go as low as 650 lph. For an explanation why read the article on the bottom of this page: http://www.cichlids-aust.com/articles.html Anthony Link to comment Share on other sites More sharing options...
Ged Posted February 14, 2005 Share Posted February 14, 2005 The suggestions you will recieve will vary. The norm seems to be anywhere from 3-8 cycles an hour. Industry seems to state 3-4 times an hour but many people in the hobby aim for 5-8 cycles per hour. So using this as a guide the LPH will range from 495 lph to 1320 lph. IMO I would be more comfortable with the the flow cycle around 7 times. This may not be achieved with just one canister filter. For example the Eheim 2228 Professional Canister has a flow rate of 1050 lph. It will also depend on a what type of fish you are aim to put or have in the tank. A couple of weeks ago there was a good thread on filtration. http://ace.ipbhost.com/index.php?showtopic=1567&hl=flowrate Hope it helps Gerard Link to comment Share on other sites More sharing options...
Ant Posted February 14, 2005 Share Posted February 14, 2005 Sorry Ged, i know i'm probably not as experienced as you but i think anything above 6 times an hour is far to excessive and in smaller tanks like this one will create too much flow. Just my oppinion, im sure there are loads of differing oppinions but 5 times an hour works for me. Anthony Link to comment Share on other sites More sharing options...
Ant Posted February 14, 2005 Share Posted February 14, 2005 So I guess my point is it all depends on your tank size, fish in the tank, the way the filtered water enter the tank etc etc. This is the point i was trying to get at Link to comment Share on other sites More sharing options...
