If you don’t have rainwater or filtered water it’s no biggie. Just let your water directly from the tap, sit in the sun for a full day. Chlorine will off gas in that time and the water will be perfectly fine for your microbes to thrive.
If you want to make straight compost tea, the same recipe applies.
NOTE: microbiology is alive and needs oxygen to live. Be sure to use your brew within 4 hours of removing it from the air pump. If it smells terrible it’s dead/anaerobic – don’t use stinky castings or tea. Tea should have little smell once the fish emulsion is eaten.
