building a 60 gallon tea brewer

[Mia]

I am planning on building a 60 gallon brewer and am trying to figure out what air pump and method of diffusion I want to use. I know MicrobeMan says the Ecoplus 5 is good up to 50 gallons. The specs say it puts out 88 liters/minute.
There is an Eco 7, that is considerably more money, but puts out 200 liters/minute.
Is there such a thing as too much air or is bigger better?

As far as diffusion I know I can always go the PVC route but there are a lot of interesting diffusers to choose from. I'm willing to spend some coin on quality. Any suggestions?

These look pretty cool but don't know if something like this would work:http://www.aquaticeco.com/subcatego...rs?green=F1C58F26-6E89-5C5A-974B-456654A8CCFF
they say they make industrial grade ones for solvents and such.

Opinions appreciated!

i would consider 2 pumps, 4 tubes to give a total of 4 lifters...what size pump i cant tell you but with a res that size i would make sure that there is enough water movement throughout the whole res

Yeah I was thinking something similar. Two eco 5 pumps are cheaper and more efficient than one eco 7.

What is your design?

you can build a 30 gallon vortex brewer for under 500 bucks... i dont see a 60 gallon one being much more.. .maybe 100 bucks tops.

I don't really have one?
I was thinking along the lines of a simple bubble style brewer.
Does vortex/airlift have more advantage over simple bubble?Maybe more gas exchange at surface?

Have a look through the DIY ACT sticky above

if you want the oxygen in the water to be at or above 6 ppm then you definitely are going to want to use the eco 7; also, thats assuming you will only be topping your brewer off at 30 gallons. If you're going for the whole 60 gallons you should double up on the eco 7 making it 400 lpm

i tried using this equation for figuring how much you could pump based on the tea article thread,
200 lpm = 7.06293334 cfm
1 lpm=0.035146667 cubic feet per minute
0.05 cfm per gallon minimum
but I can't find the ppm with a calculation which does not factor in air pressure and temperature, I would need a dissolved oxygen meter, and its 500 dollars out of my range.

1 Eco 7 will work in a 55 gallon drum. Once you put your material in the drum, and allow a little room at the top so that it does not over flow when bubbling, you air brewing around 48-50 gallons per batch.

I have tried multiple designs in 55 gallon drums with the eco7, and they all created "quality" compost tea. The easiest thing to do is to get on microbeorganics.com, and build yourself an airlift. There are also some threads here with airlift pictures that may help you out.

They are extremely easy to build.

I really like my brewers design, which is a design that is very similar to Microbemans. Two ecco 5 air pumps. One powers the air lift, the other powers the two air stones shown.
