ryanjury Posted March 8, 2010 Report Share Posted March 8, 2010 I am pretty sure that looks like a standard pump you would use for a fountain or for the return pump for a sump or something like that.. You could stick it in your tank but it would probably be a massive overkill, there is a 1200LPH powerhead for increasing in tank circulation on trademe in palmy at the moment that might be better? Either that or buy a big ass external and get the flow and filtration up that way.. That is of course unless you wanted to buy this and setup a sump..

Stella Posted March 8, 2010 Report Share Posted March 8, 2010 Hi Sandy, I had two 3500L/hr pumps in my riffle tank (4ft, 220L). Both at once created KICKASS flow. One at a time was also pretty awesome, but slow for the fish concerned. Do you want a fast flow tank? In that case take the total volume of the tank, multiply it by 30, and the result is the minimum pump flow to aim for. How big is the tank? Another consideration is temperature. Two pumps put the temperature of my (coldwater) tank up by 7 degrees Celsius in WINTER. One pump also had a significant temperature output. Probably not much of a concern for tropical fish, but definitely a problem for coldwater ones, and if your tank gets so hot over summer that the thermostat is barely on. Alternatively it may save you on heater use though keep one in for stabilising things. As for a spray bar.. with that size pump you want a pretty liberal spray bar, otherwise you risk straining and overheating the pump. Quote Link to comment Share on other sites More sharing options...
Ira Posted March 8, 2010 Report Share Posted March 8, 2010 There are a bunch of pumps that are available in powerhead versions and pond pump versions. The difference? About an extra 20 meters of power cord on the pond version. Quote Link to comment Share on other sites More sharing options...

ryanjury Posted March 8, 2010 Report Share Posted March 8, 2010 What type of fish are going in the tank? Quote Link to comment Share on other sites More sharing options...

Nah, won't come anywhere near blowing them out of the water. A nice current at best. A lot of fish people keep are river fish and rivers flow much faster than just about any pump could get a tank moving. My 440L has around 8000 lph of flow(Assuming everything's pumping what it's rated at) Quote Link to comment Share on other sites More sharing options...
