    I almost have my brewer tweeked on air, now I need to tweek the air in my truck tank. I have a 12volt air pump I've been using and it is better than nothing but could use more air in the heat. I have 2 air pumps, a MedCo45 and an eco 80 watt or 120 watt. I looked at inverters, but came across some generators on ebay. Here is 2 examples

    Elaine Ingham has made the statement that tea sloshing around in the tank during transit is enough to keep it oxygenated for the day. She has also said that if you keep you tank circulating during transit, you're fine.

    Barry, send dr I down here and let her see the 107 deg temp in my tank, if we dont have some air on it it will burn up in a 3-4 hour window, we have to air here!!!!!

    wallz any amount of air is better than none! we have an ecoair that puts about 4 cfm into the tank it wont keep over nite but at the end of a run 3-4 hours, the tea is still alive!!!

    Phast, thanks for that info. I only spray 1 big lawn and the truck sits there 2-3 hrs. My tank is just that, a nurse tank. I have a 12 volt pump running my recirc thru an eductor and a 12 v air pump w/ a pond stone in there. I was thinking if I pick up smaller and more stops I would want more air for more time. If Dr E says so, ok. Do you moniter DO out in the field?

    Wallz,
    You should be fine.

    Treegal,
    You're right every situation is different, you need to aerate.

    I'll pick Elaine's mind more when I see her this week.

    as long as temps aren't to high and you dilute your tea with more water and you don't add food, your fine with out aeration. i find if i add more food, molasses,fish,ete to the tank when i leave in the morning DO drops fasssstttt. part do to more ppm in the water"tea" and mostly because of more bacteria growth.

    it's nice to have a second mix tank to draw from to mix more food + tea at time of app

    also maybe set your return up higher in the tank so as to aerate the water when it falls back down, breaking the surface tension,like tim w's tea brewers down pipe

    I agree growingdeep. I only put water and tea,1:1, in the nurse tank, fill my sprayer and add any goodies in once I have my recirc on. I spray my 40 gallons in 15-20 minutes, so the DO doesn't nose dive.

    there it is, we feed and batch out 1500 g's in a day, 200 gallons + per truck and its hot and feed and not that watered down.
