Hi all, I often read people asking about the water parameters of their aquariums. Is this something I should be looking at, and if so what materials should I purchase to do so? Do I really need the pH meters, nitrite meters, etc?

I have 3 tanks including a 30 gallon with angels, an L204, some bolivian rams, a 5 gallon with endlers, and a 20 gallon with a blue crayfish and some dither fish. Right now my goal is to set up healthy and happy community tanks and hopefully one day I'll breed angels.

Hello, I'm just getting into freshwater fish, so far I have 3 tanks, multiple fish, and more questions than answers. I look forward to hearing everyone's stories and suggestions.
