I will go with fan jets I think see how I get on . I go with the Gardiner x2 100 degree fan jets . They look like they give a good rinse even on half flow . So I save water as I only have a 500 litre tank and I be topping up at spotless water site so the more water i save the Better . I know what you mean Davy about all the videos there are a lot on here and all different views . So I think I will embrace the Fizz ?Are fan jets ok for rinsing when doing gfs cleans ?. How do you determine what angle fan jets you need , I see they come with several options ?..
