Can someone help me out please? The problem i have is that my water was very clear the other day and when i tested my PH it was like 6.2 so the guy at the fish store told me i had to get it to 7.0 and to add this powder like stuff called PH increaser. I have been adding it a little at a time for the last couple days and now my PH is at 7.0 but i now have a different problem my water is very cloudy and it seems like my light colored gravel in the tank has like a dark kinda covering like their dirty almost look to it now. What can i do to get my water clear again and my gravel back to normal? Should i just wait it out or is there anything i can do? Thanks in advance.
