Aquariums

Christopher Michael asked:


I just bought a new fish tank that I’m filling with freshwater fish tomorrow, but I need to know if its absolutely necessary to have a canister of aquarium salt in there. Petco does it. I’ve never seen it done before so what, if any, are the benefits?

el aji asked:


I found a aquarium light that has 3 switches, one for white light, one for blue and another for the led night light. Should I be running the blue and the white together or run them at different times. And if you run them together why can’t I just buy a cheap dual strip florecent light and replace one of the white bulbs with a blue bulb?
