yes, buy PH up and PH down. Stick it in your house. Thus making it a house hold item. Then you use it. seriously after reading hundreds of threads, you can lower with household items but everyone who replied to those threads said buy PH up and PH down. household stuff just doesn't work as well.
i use apple cider vinegar for ph down and bakeing soda for up or tap water cause my tap water is like around 7.8
