kbrookes Posted November 7, 2014 Report Share Posted November 7, 2014 I've just added a Bio Pro 1800uv to my 450 litre 4x2 , complementing a cheap 2000lph internal filter. The filter and inflow side of the canister are in the back right. Bother the filter and canister out put to (separate) spray bars. As a result I think I'm getting a slight dead spot in the tank in the back left. Should I take the spray bar off one and have it point it's outflow from top back right to top back left? In assuming that i'd be better using the internal for creating flow? Link to comment Share on other sites More sharing options...
yellows Posted November 7, 2014 Report Share Posted November 7, 2014 Yep take the spray bars off you'll have heaps more pressure and even try shortening your outlet pipe to so the water doesn't have to pass through so much hose Link to comment Share on other sites More sharing options...
