TWS,
We used pH'ed treated well water, I used a sulphur generator and injected the liquid sulphur into the irrigation pond to keep my ph in the 6.5 to 7 range. We pumped water from this pond for watering the course.
I installed a new irrigation system at the club I was at before I retired, it was state of the art for water management, distribution and computer controlled. Hell I could sit at home and operate my system. Incorporated into that system was a state of the art Fertigation system which allow me to basically spoon feed the turfgrass, by need and location. So injecting the compost tea at a rate of two to 5 gallon/acre of AACT was very easy to treat the entire course. I also used a 500 gallon tank we would fill with lake water and add 10 gallons of AACT an sprayed the greens extra, that gave me approx 5 gallons of of tea to the ac.
What I saw from those treatment is why I say you should use AACT but my suggestion would be to do a good flush with ph'ed water and AACT. After you have finished the flush, drain the rez and refill with straight AACT. I would not let that set more than 24 hrs as without continuing feeding and aeration the microbes will die and that can create problem.
When my current grow reaches the rez and gets 4 to 6 nodes I will start a program of every two week tea apps, which I will do as explained above. after 20 hrs or so I will flush the remaining liquid and microbes (mostly dead by that point) from the bucket. I know this sounds like a lot of work but folks you don't want biofilm to form in your rez.

In the early 90's I attended the Soil Food Web seminars on biology (the Soil Food Web), compost, compost teas, and microscope usage. I have done some consulting with organic farmers in NorCal on both compost and teas also on the use of EM1 in agriculture. Just spoke to one of them the other day seeking info on a golf course he is a member of, and he said he is now using EM1 on all of his crops (24 different veggies and fruits), over 1200 acres of organic farm, damn cool I think. When I lived out there he would give me boxes and allow me to go pick as much organic canning tomatoes I wanted, the last pick was 250 lbs. That was a nice treat.
Sorry for the rambling but just smoked some of my latest grow, the CC/BBGA (Cotton Candy female/Blackberry, Grape Ape male). I love new grows, LOL.
Peace out and Happy New Year to y'all,
GR
