stewpid Posted October 29, 2011 Share Posted October 29, 2011 Just need to ask a quick question from experience bros here. If the overflow box rating is 1200l/hr,what is the reccomended return pump rating if it has to go through a chiller. Help much appreciated!

SRC Member tunicate Posted October 30, 2011 SRC Member Share Posted October 30, 2011 Below is a chart of Eheim pumps. A typical sump tank to display tank height is about 1.5m. Based on the 1260 line, it'll give you about 1400L/hr at that height. That will reduce to 1200L/hr or less if you hook it up to a chiller before returing to main display. BTW, a 1200L/hr rated overflow box is really quite small. Is this for a nano setup? Quote Link to comment Share on other sites More sharing options...

Is this for a nano setup? yeap it is a nano/pico setup...planning on a 30litre display and a small sump(20litre or 40 litre sump)planning to use a rio 10HF or eheim 1250(abit high unless i get a good price off pasar malam thread) Quote Link to comment Share on other sites More sharing options...
SRC Member tunicate Posted November 2, 2011 SRC Member Share Posted November 2, 2011 A 1200L/hr flow in a 30L display will give you 40X turn over rate. That would be a little too much. A 1250 would give you a more normal 10X turn over rate, and less if you include the chiller. Quote Link to comment Share on other sites More sharing options...

SRC Member tunicate Posted November 19, 2011 SRC Member Share Posted November 19, 2011 Hi, I was looking at the chart. What is an ideal flow for a 3-2-2 tank? A 3-2-2 comes up to about 320L in volume excluding the sump. Folks aiming for 10x circulation would shoot for 3200L/hr. This 3200L/hr could be the sum of 1200L/hr(return flow) + 2000L/hr(wave maker) This would translate to, for example, an Eheim1260 return pump and a Koralia 2 wave maker. An Eheim1264 can also be used if you prefer higher flow rate going thru' your sump. But there're no hard & fast rules with these things. Note: The stronger your return pump, the thicker your overflow pipe will need to be. Quote Link to comment Share on other sites More sharing options...
