    Okay i am trying to absorb as much as i can about tea, take good compost with good starting numbers for good bacteria etc, brew in oxygenated water, what is the range of dissolved o2, i know that it goes bad fast if the numbers go low, but is there such a thing as too high or can it go bad if it is too high,
    or do you bring it back down by adding fish or molases?

    Minimum 6 PPM; good if 7 to 9 PPM; I've had excellent CT where the DO2 was around 11 PPM.

    That means it stays above 6ppm the entire brewing cycle. Typically you'll see the DO2 go down in the middle of the brewing cycle, so it's important you're checking throughout your entire brewing cycle.

    I'm curious. If your pump is already maxed out, how do you mitigate this (assuming you only have that one pump)?
