Air Pump for 10 pots

HI All

I wish to try an make a homemade air pump to cover a ten pot system. I can locate the air stones locally and the tubing I have already. Any suggestions or has anyone actually done this successfully. I wish I could afford the same as my other ones I have but monies tight and Im trying to make saving where I can.
Thanks

You need a legit pump from a hydro shop. Not entry level either. You might also consider a large stone rather than splicing several small ones per site.

Check YouTube videos on how to make really simple to make

thanks
