I have a ph of 7.6. During a cycle in one of my tanks the ph kept dropping to near 6, stalling my cycle. Water changes absolutely helped get the cycle started again. If his tap is 6.8, then it makes perfect sense that water changes would help, along with leaving the ph altering chemicals out of the tank. Simple.
No way could water changes alone lower the ph in his tank.
