I’ve never used that brand tea so not sure what color it should be but usually the clear water will darken as it brews to a brownish color. Just follow the directions on the product and you’ll be fine.
Are you saying the end tea was still clear like water after the brew was done?
I would suggest bubbling for closer to 24 hours-36. 48 would in my opinion be the max. 24 hours depending on the mix would be bacterial dominate and that’s what you want. 48 hrs and it becomes more fungal dominant. Just make sure you smell it before using and if it smells earthy your good but if it smells bad like wet rotting grass toss it and start again…you’ll know.
As far as all the bubbles up top (foam) it isn’t necessarily an indication good or bad. As long as you were getting a decent amount of aeration with the set up that’s fine. My pump is similar to this one
as I wanted to have the larger capacity in case I brew a trash can size brew but usually just use 1 or 2 air stones
in a 5 gallon bucket usually with only 4 gallons of water because of the foam with a saucer underneath the bucket for the foam overflow.
I initially used a smaller aquarium pump as I used to have many fish tanks set up and they worked fine. If I need more tea I’ll use 2 buckets and brew 8 gallons at at a time and that’s where the larger pump shines.
The 240 ppm would be fine to feed them the tea straight up or you could dilute it too. I use boogie brew tea mix and when making the normal strength mix (1/2 cup part A and 1/2 cup part B for 5 gallons water) it ends up about 450-550 ppm at least last time I actually checked but I don’t bother checking it anymore as it was pretty consistent ppm from brew to brew. That tea I usually then mix it 1:1 with RO water and feed. You don’t want to adjust the PH of the tea after it has finished just feed.
I usually just dump the mix into the bucket of RO water and brew it. I have bags I can put the mix in but don’t bother anymore. If needed based on how I apply it I will use a big strainer (if I use my battery powered pump as it can clog from residue) that people use in the kitchen and pour it into RO water mixing 1:1 usually just pour it in without straining when using a watering can like one uses for house plants or outside garden…any left over stuff I’ll scrape out and top dress into pots or put in old soil that I’m re amending or into my compost pile.
Make sure to clean everything used in brewing afterwards…bucket, watering can air stones etc…after cleaning the air stones I run them upside down for a bit to help clean them out for next use otherwise you’ll replace them more often.
