IO just put ph buffer into a water change(into a 5 gal bucket) then I let it sit for aBOUT 1-2 Houres in w/ a power head and heater. when I went to go put the water in the water was like white. can you mix buffer into your water change. I poured it into the tank thinking the cloudyness would just go away but it is still there. now the buffer I use says you can not over do it(go over 8.3) what do you guys think. my tank is white!!!!!!!!!!1
