What size pump is everyone using? My last two batches of tea I had zero foam.
I haven't added alfalfa yet...but will be on my next tea.
I use either two stones on the smaller active aqua 50 liters/minute or three on a 110 liter/min pump. I always have foam, even if I just do Caps Bennies alone. I am by no way an expert but I would think that you need to evaluate your method if you are not getting any foam at all. From my understanding foam indicates many things but in general that you have an active tea. I used a smaller aquarium pump one time, it came with the Bountea kit I had bought, and I did not get foam and it smelled like vomit/sour-ish yukky odor.
Maybe you can use a water pump? I know that I read on Microbeorganics web page that smaller aquarium impellers do not damage the biology in teas.
Maybe someone else can be more helpful.
Well, it depends on how much resistance there is due to flow through the tube, gravity pushing back from the water it's submerged in, pushing through the airstone itself, etc.I wonder how to translate the psi to lt/min?

I think when an air pump is rated in terms of flow rate they must be making assumptions about how little resistance it must push through- too much and flow rate would drop. Likewise when it's rated in terms of pressure they must be making assumptions about how much resistance there is- too little and pressure would drop.
Really, they should be telling you both maximum flow unrestricted and maximum pressure fully restricted. Sorry that's not very helpful.
Just wanted to say that I just brewed a tea with Water, Molasses at 10ml per gallon, and added Foilar and Root packs and after 36 hours I have a at least 2 feet of foam from a 30 gallon brew with 4 airstones and an Air-5 pump.
Ph has stabilized at 7.5..
I have noticed that you should clean stones every time!! When I don't have good foaming its because of a clogged airstone and the tea smells bad. I rotate them out, I bleach and then boil them!
Cheers
I have just started boiling mine too after reading a post on here. I dunk them in Physan 20 solution (mild) or bleach (mild) and put the air tube on and blow it out. Turn air off, dunk, let sit awhile, blow out. Repeat a few times over a few hours then boil. Mine have yet to get clogged.
I foliared straight tea (tbs each, ewc, alf, humic, kelp, blackstrap). No ill effects. Question..should I add a drop of eco friendly dish soap or is that bad news for the micros?For actual foliar feeding I would go light. Maybe 1/2 cup per 10 gallons.
Still no foam.....I'm adding alfalfa meal next week and one other thing I noticed was that the water was pretty cold. I didn't bother to check the temps...but I'm pretty damn sure it was below 70 degrees...which I think would inhibit microbial life from populating.

Hey Cap will using SM-90 in my mix kill my tea? Thanks man
