    So, Sunday I shook off the dust from my trusty old wallet and lavished out on an external filter.

    EHeim Professional Pro II.

    Now all the articles and advise I have read here and elsewhere kind of says that you should turn over the volumn of the tank about 10 x's per hour.

    I only have a 90cms tank and depending on which calculator you use can be anything from 105 litre to 153 litres( hummmmm??? ).

    Quick ask about, and an educated thumb suck and I decided about 100 - 110 litres.

    Therefore 10 x 100 = 1000 litres per hour.

    Bought a 950 l/h machine.

    Must say the quality and detail of the product was great, even a small sachet of vaseline for the O'Rings, includes all filter material, tubeing, suckers, clamps etc etc. One stop shop.

    Without much effort everything was in place and the grand switch on was enacted.

    Well, faceplant of all fish against the far glass panel. Fortunately, there is an adjustment to control the flow.

    Got it all stabelized and settled.

    My question is - is 10 x per hour really necessary or did I just mis-interperate ( hope theres a spell check here somewhere ) or was it overkill for my size tank ?

    I must say that watching the danios etc speed surfing from one end of the tank to the other is really exciting, although I think the harlequins are suffering a bit with exhaustion ( wheres that spell check ). Apart from the Harlequins all the other fish seem to have settled down.

    The water is clearer than ever and to see the plants swaying with the flow is very satisfying.

    If I recall correctly I think the volume of the tank needs to be filtered 4 times an hour. 10 times seems a bit excessive.

    not a set rule bud...

    4 min but 8-10max! the issue is getting the ferts to the plants, unlike fish they cant chase there food so we have a high turnover witch gives us piece of mind that all the goodies is getting to the right place.

    Minimum of 4 x per hour.... Most guys doing high tech planted tanks advocate 10 x per hour.... but not all of this has to be provided by the filter(usually made up of filter and flow pumps)... Maybe split your return or even better - use that spray bar attachment you should have got with the filter and position it just under the water surface,blasting along the surface,lengthwise of the tank....

    on a personal note - my Harley's cope with flow of 80 x per hour(6000l in a 75l tank) rather well in my high flow tank.... they will soon get used to it....

    Hehee... That's a great read.

    I would say 5-6 times is more than enough. But in saying that, I would also add a small pump like a hydor corolia in there as well. I have one for my cube, as soon as she is alive again.

    LOL - great read :D

    I suspect what happens a lot in our hobby is that somebody says, '4 X per hour'. The next person says, '4-5 X per hour'. Then the next person says, 'if 5 X per hour is good, 8 X must be better'. And then it becomes a hard and fast rule that anything less than 10 X per hour and you are irresponsibly killing your fish and torturing your plants. I've always though 10 X per hour sounds like a bit of an exaggeration.

    PS - I'm the spell check :p

    PPS - Happy birthday - nice birthday present you bought yourself. 67 really!? Lloyd and Worsie can wish they'll look like you at 67 :D

    Update

    Now that I adjusted the flow rate down a bit, things have settled down nicely.

    Unfortunately, 2 of the harlequins didn't make it.

    Everyone else is happy as a " fish in a pond " !

    Thanks again for the clippings. It was great to see your tank and meet your wonderful family.

    Hugs. Skye!
