    Air pump sizes

    Am building a airlift return to pond to help in lots of ways but mainly the running costs . Am thinking I'll need a new air pump and looking at the jeboa ones but haven't got a clue what size to get ??

    Get a 100 and run the nexus (200 lrts k1) and airlift.?? Would I need to bleed off ?

    Get 2x 35s one for each nexus and lift .

    Any ideas of what out put I'll need

    The most expensive pumps seem to have the higher power consumption!! .

    Hailea or jeboa seem to come in all round cheap to buy cheap to run

    I run 3 x Jeboa 100s cheap as chips quietish, I got them expecting to replace them every year but 3 years on there still going, can't fault them even during the heatwave they survived and it hit 50 degrees in my fish house

    I have one on a moving bed, another feeds a retro bottom drain and my hospital tank (which is a waste I know with no fish in it) and the last feed three discs in my lower pond, I do bleed some air off though, I could probably get away with two, I should tighten up really with the ways things are going

    i know the charles austin ET80's are rated at 85w. but mine has always run at around 60w.
    the wattage depends on load, same as water pumps.

    in fact it's been a while since i checked my ET80 with an energy monitor so i'll pop it on today.
    i have a spares kit i bought with it 3 years ago but haven't used it yet.

    but i think the output decreases over time with air pumps as the diaphrams soften up, and the magnets weaken over time with use.
    but it also gets quieter too.

    Yeah I had the et100 and seemed noisy and it was outside and didn't want to piss the neighbours off any more than I do anyway so sold it to frim . The jeboa is looking very good on manufacturers numbers but we all know what they are like .

    Just not sure how best to run my set up 1 big pump 2 little pumps and what size I will need to roll 200 liters k1 and more importantly the airlift

    Found that myself recently when looking into wether I could change out my 2 pumps for 1 newer larger pump but it made no sense,Iím currently running an ea 70/75 and a haliea 60ish size,both seem to be low wattage ish so they can stay for now

    It is tricky. I remember spending ages trying to decide what I needed for my set up. Mostly all guess work lol

    I ended up with an Hi-Blow 80XP pump for air lift and moving bed (210l of k1) and it covers both needs well. As the airlift runs deeper than the filter, I have the valve fully open for the air lift and regulate flow by adjusting how much is fed into the bio i.e. if I want more flow from the air lift, I reduce the amount of air going into the bio and vice versa.

    The only downside to sharing is it can make adjusting the flow of the air lift a little tricky as it requires the tiniest of turns on the air valves to make a noticeable difference to the air lift. (I gauge the output flow based on how high up the air vent the bubbles come and compare that with how frequently the drum cleans).

    You also have the issue that if that one pump goes, it has a pretty significant impact (although I have a separate 40 air pump for the bottom drain that I could always swap over if needs be).

    I think the only the downside to running two is it'll probably use slightly more electricity than running one bigger one.

    If you want a separate pump, I'd say aim for around 40lph air pump for the air lift. You might want to go up to 60 just so you have some extra to play with (or if the depth of your airlift is greater than the optimal depth to run the 40 air pump at), but to avoid the flow being too much for your filters, you almost certainly will need a manifold to regulate flow.

    It is tricky comparing models, as some are rated to a certain output with zero back pressure, whereas some are rated to a certain output at a certain depth. So you are not necessarily comparing like for like.

    If I run a jeboa 80 55w and split it between the nexus and lift I'll save 80 Watts in running costs .

    Save 95 Watts if a jebao 60 would do the job

    What's the average cost per watt these days

    If it's a toss up between the two, I'd say go for the 80 option.

    There's a real risk the 60 won't be enough to turn the bio over, after the air lift has used what it needs.

    The 80 may use 15watts extra, but you'll still be saving loads in the long run compared to using a conventional pump.

    Plus if the air stones start getting clogged up with bio film etc, you'll probably need the 80 for the extra pressure it can pump to.

    Just for info AJ,

    In the last 5 years I have run 3 pumps.

    A Charles Austen ET - Absolutely bullet proof, reliable, the rated output is the minimum you'll get, well built, noisier than others, expensive.

    A Jebao PA100 - Good pump, very quiet, internals looked like new after a year's use, economical, but significant lack of performance when pumping under pressure (i.e 5 foot + below water level.

    And my newest pump.....

    Aqua Eco Hi Blow - All the best bits of the 2 pumps above, and therefore probably the best value as it is similar money to the Jebao pumps, but more efficient and powerful.

    Bought from here:

    Yeah mate the more I think about it the more sense it makes to go the 80 . I'll keep my ea 70 as a back up . Thansk for your advice mate
