    Eheim external filters - stated flow = actual flow?

    The output of a filter is measured at the max amount with no media at the ideal height. All manufacturers state that. Eheim's website (and apparently JBL stated above) states the normal output they would expect from the filters. The '10x' volume takes into account that filters in general only...

    I would position both inlets next to their Lily pipes. Complete the 'circuit' if you like. So the rear right one I would put front right. Other than that looks good to me. Glass spraybars do exist but as far as I know they aren't made anymore. I guess there was a lack of demand. So you...

    Best Inlet / Outlet for external filter.

    Its not so much the lily that is the problem it is the glass. Glass spraybars and lilys etc are much thicker, not in their actual outer diameter but in the thickness of the actual glass. That therefore restricts the flow a little. So whether it be a spraybar or lily pipe you get a slight...

    Internal to external filter

    the external will more likely be much better at filtering but with you will need a much higher lph than your internal. For example a Fluval3+ is rated at 700lph and due to it being internal then as long it is cleaned weekly then it will be closer to it stated than as external as the flow...

    The flow reductions were 'factored' in when the 10x 'suggestion' first started. We estimate each filter is around 50% actual of the stated lph so in theory the need here is 5x.
