Is this pump adequate for making tea?

So I have made a couple batches of ewc tea and was reading that a pump with adequate output is needed. My pump has dual outputs and is 4 watts, 2500 cc/min and 4 psi. Is this adequate for making 5 gallons?

Not imo. This is per MM's site:

The outcome of this research was, the estimation, that the minimum flow required from an air pump to make compost tea while maintaining the DO2 at 6 PPM, is 0.05 CFM per gallon while the optimum flow is 0.08 CFM per gallon or greater. (the only exception was when utilizing airlifts)

This means that most aquarium pumps will not work with a 5 gallon ACT maker, no matter what a couple of guys from Texas say. Two gallons, perhaps.

^^^^ yuppers get yourself a commercial eco plus on craigslist for half the price.
(Plenty of failed hydro growers selling gear online for cheap.
