hello i need help with a ph level

hello my ph level is at 7.8 is thta too high or will it kill them AND I AM ON WELLWATER BTW TOO

hell ya it will slowly for sure. go to shoprite or whatever and buy some distilled water-like 1.30 a gallon. is ph perfect. are you feeding nutes? if so this high ph will surely cause a lockout of essential nutes

If you are even looking to save a long term buck, then just buy a bottle of vinegar and splash that in each batch of water until its right..or squeeze some a lemon..
