Janelle Posted July 30, 2007 Report Share Posted July 30, 2007 At the moment I have a second hand Shark ADV Powerhead (I think that's what it said on the manual) which does quite well with my tank (it came with it when I bought the setup). I like it but I have it pushing water from the back to the front of the tank so the other corner in the back doesn't get much flow. This probably suits some of my fish since they choose to sleep in that corner. However, the fish in my tank could all handle a faster flow, so I'm thinking of getting a directional powerhead to replace it, like the one in this link: http://www.trademe.co.nz/Home-living/Pets-animals/Fish/Pumps-filters/auction-110637348.htm Would this one be good for making the flow a bit more long-ways along the tank? The tank is about 61 cm long x 30 cm wide x 51 cm deep and filled to about 10 cm from the top to make about 75 litres in volume. The pump in the link is for 100-300 litres so as much as I want a stronger flow, should I just go for the one recommended for 50-100 litres instead? How would the direction of the flow affect the water in the tank? Is there a recommended depth/direction so the water circulates properly? Or should I just stick to my Shark ADV, or whatever it is? Thanks for any help. Quote Link to comment Share on other sites More sharing options...
