DiverJohn Posted March 1, 2005 Report Share Posted March 1, 2005 Hi Everyone I am looking at the process of setting up a sump/ trickle type filter in my new 5 footer. Wondering if any of you running sumps could give me some measurements of your overflows, pump capacities, and maybe head height I am thinking along the lines of a 40mm overflow with 1000-1200 lph (@ zero head eg: Ehiem 1250) pump which will have to pump up to approx 1m. How does that sound? Too much? Appreciate your help John Quote Link to comment Share on other sites More sharing options...
Pies Posted March 1, 2005 Report Share Posted March 1, 2005 DiverJohn. I have details of my sump/overflow etc in the saltware section, my thread 'first look at the new setup'. I have a single 40mm overflow, which I pump over 7,000 litres an hr through, no problem. My other tank has 25mm overflow and handles about 3,000 litres an hr. My old tank (similar to IRAs) had 15mm overflow, which is fine for about 1,500 litres an hr. 1M head just about any 'real pump' can do this. I would look at an ehiem 1060/1260/1262 or IWAKI or similar, the 1250 (if memory serves me right is just a small pump? I would look for larger). Depending on if you want submerged or external.

DiverJohn Posted March 1, 2005 Author Report Share Posted March 1, 2005 Cheers for that Pies. Just trying to get a handle on this and the post you mention is realllllllly long ... All the pumps you mention are 2000 lph+. If I look @ the eheim specs http://www.brooklands.co.nz/eheim/techinfo.htm (for those interested) i am guessing the 1250 I was thinking of getting is the baby of the 12** range. Would you have any info, or method to work out an expected flow @ 1m head? The max head is 2m. The drop isnt linear is it? You say your 25mm over flow handles 3000 lph. Is that 3000l out of the pump(s) or is it an actual 3000l through the overflow? What effect does submerged / external have? Perhaps I should also point out that the tank is only 560 ish l (5'x2'x2') and I will have 1 external Canister filter (probably a proII 2028) because i like the reliability and redundancy aspect of more than 1 filter. I think that between 1500-2000 lph of filtration would be ample (oh yeah its FW not marine ) Quote Link to comment Share on other sites More sharing options...
chimera Posted March 1, 2005 Report Share Posted March 1, 2005 You say your 25mm over flow handles 3000 lph. Is that 3000l out of the pump(s) or is it an actual 3000l through the overflow? both. my tank is 5'x2'x2' as well, but also saltwater. of course, you dont need the water movement like you do in a saltwater tank but as pies says, 1250 is still a pretty small pump. i use it to do water changes! i would opt for the next one up, maybe a 1060 - but i guess that depends on the rate of filtration from devices in the sump. just remember the 'per litre' always sounds more than it looks coming out your plumbing!
