Clear is clear, there are BW clears and BW stained water then CW clear and CW stained.


I have "stained" water in my angel tank, yeah its hard to see em but the fish are much much healthier in BW then they are on CW

(BW= blackwater aka amazon river basin IE rio negro as an example but there are many BW environments in the world including asia)

(CW is clear water)

If you can drink it, its not fish safe.
