AACT Brewing Question

Hey rollitup community, I've recently have been getting into brewing compost tea and my question is do too much air stones have any harmful effect on the microbes? (Read a post about AACT that the airstones, happen to kill the microbes or something?)

No, not at all. You will not kill aerobic bacteria due to too much oxygen. Most ACT systems lack enough oxygen.

The only thing that I'm aware of that could potentially kill beneficial bacteria in your brewer is if you are using a stocking or some other type of filter with a very small micron size you could potentially trap/kill fungi and prototzoa.

If you brew often airstones are a PITA because they get clogged. I just use a pair of small air tubes and they get the job done just as well or better without the airstone. Good luck!

Hey Supra.....the sun is coming up in the near downeast ME. What kind of tubing do you mean? How do you keep it down? Thanks.

Cheap airstones are a pain. I was having to buy a new one every third or fourth ACT I was brewing. Then I decided to quit fucking around and I bought a good oxygen diffuser and the thing has been great. I've been using it for 6+ months now, brewing 1-2 ACT's a week and all I do is wipe it down after a brew and that's it. Simple as can be, and it works like a charm. I'll throw up a link to a product review video of the one I have:

Its the size of the bubble that makes the difference. Too large of air bubbles wil disrupt bacteria and fungi growth. Too small of bubbles will slice through bacteria and fungi like a knife. Having larger stones is better though. Too small stones clog to easily and have to be switched out a few times.

Noice, Thanks all.
