ive never paid much attention to ph and hardness, cause it is hard to change and keep constant. Plus i have heard so many times "rays can adapt"
That's cause we as ray keepers "adapt" to hearing what we WANT to hear and ignore things we know to be incorrect or unknown cause it's easier then learning and understanding the correct way. Haven't figured out yet how this mindset fits into the KISS method, but I have a feeling I NEVER will..... LOL
