hi all, just curious, i KNOW i'm not the only one. i have a thriving 125g tank. 150ish lbs of live rock, full of flowing growing common lps and leather corals, i do 4 or 5 50 gallon water changes a year, i top off with ro water and i feed my tank (very lightly) that is it. i see this word test kit thrown around alot. am i the only one that doesn't own one? infact i haven't tested anything other than salinity for the past 5 years or more years. anyone else care to chime in?
