For the life of my I cannot get the air lift to work using a tank to push water up. I was able to to the T connecter from the bottom of a bottle setup working, but I don’t want a bottom/gravity fed system. I’d like to have a tank on the floor that I know will not leak.
I have the 9904 Petco Pump and I used the instructions on the DIY pdf(bought the exact tubing specified). After tinkering with it I was able to get it to sputter just enough to fill up 1/4 of a red plastic cup in a hour.
I also used a 1.5 liter bottle, a 1 gallon water bottle, a 2 gallon bucket and a six gallon storage tube for the reservoir.
I tried pairing the ports up on the pump, also used them all individually at the same time etc… no luck.
