    One warning -

    No need to waste time warning me.

    Pointless to dialogue with rude people.

    I will rescind my membership here. Thank goodness there are 7+billion people on earth. You can always avoid an idiot.

    If treat your system like an NFT (water level) and water fall into your grow beds, you will be JUST fine...

    Lose the air pump and save yourself headache.
    Love the experts! You maybe have a degree in agriculture?

    Could you just use a venturi to suck in air, if the flow conditions allow it? Although putting in the restriction could increase the load on the pump to the point where it is not a practical alternative, I imagine.

    Whats the air pump for???

    In My previous AP systems, I never used an air pump. Just curious. As I build out my personal solar, switching to Solar power pumps is on that horizon.

    For my AP system I used 1 pump with a float valve as to minimize the power usage impact. Only took my electric bill (at the time) up $10/month

    You can always change the power supply later if you choose. This is a relatively expensive proposition as I found out.

    An air pump has to run along with the water pump. Not all schemes require 24 hour operation.

    A solar panel, will only produce useable power for a couple hours before and after Full Noon. Dawn till 9am, and 3pm - sunset, will have very little power to run a pump with.

    You may need a more extensive system to run a pump 12 hours a day. Any need for a couple shots of water at night ? How will night time oxygen get to the system ?
