So I took my water out of my new tank that has been cycling. He said my PH was way to low. It was like 6.3. I have never had to buffer the water or any of that before. What do I do. He gave me no instructions but gave me 2 things one is Buffer its like a powder or something and the other is PH up. He said I have to have buffer for the other to work or something? So what do I do? Just tell me what to do?
