      It is really fun to watch the things you come up with.

      Does air lift work for every pond and filter system or only for certain pond layout or media type ?

      I don't think it will work with a pressurized or bead filter.......you can always change your filter. Figure up your electricity savings.

      Air lifts are effectively gravity flow systems and won't work on pressurized or highly restrictive systems.

      Kent, how much water are you moving for how many amps?

      I'm moving about 3600 gph at a 4 to 6" lift for just over one amp .

      That's great, it's a double deal because you get an aerated biofilter and you don't need a water pump.

      Questions, questions, and more questions

      Hi Kent

      Good threads never die they just keep generating interest

      Some more questions, that probably show how confusion is taking over my thought processes - again.

      How do we size the pump at 2, 3 or 4 tubes? Are there other factors apart from needed throughput and filter chain restriction?

      Is it correct that due to the low suction of the pump, drawdown in a filter chain, is not a problem?

      Do these pumps have enough suction to pull through this train of filters? Even if they are actually inside a BioFilter, can they also pull through a DIY sand and gravel filter which is in the same filter circuit

      Does it have enough “pull” to bring a 1000-1500 GHP through a filter circuit consisting of Skimmers to two Bio-filters in 66 inch High tanks, to 72 inch high Ozone contact tank, to 72 inch high Ozone dilution/dissociation reactor and back to pond TPRs?

      Is your pump/dilution reactor designed for scrubbing CO2, and other natural gasses, out of the water? Also can it be used for an Ozone dissociation/reaction chamber, after an Ozone contact tank? Maybe as PVC is a “good” material to use with Ozone it works for both? Would you recommend floating bioballs inside the inner tank of the dilution reactor - if so what depth of bioballs, or percentage of the water column height?

      In a 2 chamber system consisting of an Ozone contact tank and a separate Dilution reactor Would you trying to incorporate a foam fractionator into the dilution reactor, or would you keep it, just like many commercial designs, at the top of the Ozone contact tank? Is it an either or situation?

      When they are ready to buy, should forum members PM or email initial designs you for component or system costs? Is there a direct link to components, and their prices on your website? At time of purchase of components from you, can you help forum members with constructive criticism to refine their designs into something specifically workable for their needs?

      For Ozone compatibility - are your pumps all PVC or other compatible materials?

      Please take a moment to bathe in the warm respect generated by your forum contributions.

      John

      The type of air-lift hub and collector are determined by the way you decide to use them in your system. The total flow rate desired will determine the number of tubes and the amount of air.
      The draw down through the tanks would be the same for any flow rate by any type of pump. It doesn't matter how the water is being removed from a tank. Flow rate is flow rate. The difference is an air-lift doesn't produce much head and can only be efficient at low head heights of about 6 to 8 inches or less.
      As ain all gravity flow systems, large piping reduces draw down. I am not a fan of more than two tanks in series. Usually pre-filtration and bio then back to pond.
      The restriction created by the media in a sand and gravel filter makes them a poor choice for air-lifts. Other more free flowing fines filters are better.
      You can pump through any filter and depending on how the ozone generator is set up you should be able to flow through it as long as it is at water level although I've never used any ozone.
      It will off gass just like any other form of aeration.
      My hubs are made from eurethane plastic and pvc so they shoud be ozone compatible.
      I have seen my air-lifts produce some foam but foam fractionators are better suited to small bubbles and air-lifts generally use larger bubbles. A scraper or collector can be placed on the output piping to remove the foam.
      If you need any assistance in a system design just pm or E-mail me or call me on my cell and I can easily help you with a design layout that will best fit a given system.
