I have a 24 gallon bio cube set up and i have been reading about ro/di water and i have some questions.
1) is it necessary? i checked the filtered water that comes out of my fridge and the readings were: nitrate: 5, nitrite: 0, hardness: 150, chlorine: 0, alkalinity: 150, ph: 7.2
i talked to two fish shops and they both told me different answers. one told me it wasn't necessary to use ro/di water- in fact that they use tap water. the second one told me it was completely necessary.
2) if i need to get a unit would this be a good one? :

also-- do units stay hooked up and make water all the time? or can i just hook it up and use it when needed?
