Lol yeah it's the truth. I know some people are really into every aspect of their water parameters which is great but that's just not me. Keeping rays is one of my hobbies and its something I find enjoyable and want to keep it that way. I've had roughly 8 litters from 2 different pairs of rays. Everyone is happy and healthy. Imo no need to overthink things. I've been doing this a long long time lol

But how often so you change water and what is your tank size.
