    Cheers AJ nice one mate. I'm using an EA 70 at the moment but it's not powerful enough to boil my static beds.

    not got the ET120 but used an ET80 for the last 3 years,
    been a spot on piece of kit, there are quieter pumps, like the hiblow but usually a lot more money...

    but the ET120 will be a bit noiser than an ET80
    if you have a EA70 why not add another?

    At the moment I'm running an EA 70 on the filter Dave, but It's not powerful enough to boil the static beds for cleaning, or the moving beds for the bio side. So putting another EA 70 on the filter so 1 can do the static side and 1 can do the bio side still won't be powerful enough. So I was thinking about putting a 120 lpm on the filter so it will do the bio side, and when I'm cleaning the static side I can turn off the bio side and turn on the static side for cleaning, once cleaned I can turn the static side off and the bio side back on if that makes sense.
    I've got 8 x 110mm flat round air stones doing the static side and 6 doing the bio side, so I need a lot of air running through these to get them to work properly.

    I have a smaller Charles Austen pump as well.

    They are good pieces of kit, built to last, and I believe the quoted airflow is the guaranteed minimum. i.e my ET60 puts out closer to 80 lpm.
    They are not the quietest pumps, but not overly noisy either.

    Yeah I know mate . It maybe to many and I might have to readjust things, but as you know the conversion on the 8 bay is trial and error atm.
    Maybe I should try cutting the air stones down before I invest in a new air pump.
