    Filter media order - is the typical order wrong?

    Spray Bar holes - Making them bigger

    thanks steve the water makes the far end no bother but i would be doubtful that its getting far enough along the substrate if you know what i mean, there are tall stems that move around a lot but at the base of them is fairly dead with bits of bba and poor growing low plants (although uneaten...

    vids of tank flow and surface movement ?

    hi rob I have made the holes of the spraybar bigger to reduce the speed of the water coming out it works well, you still get the full flow of the filter without the really powerful jets if you are thinking of doing it go really slow, even a very small increase in the holes size does the job...
