Water Quality Question? (Trihalomethane)

[Scubabum]

I have been having some problems over the last couple of months with frags not doing so well in my tank. I test my water weekly and my parameters are near perfect quality. Today I received a letter from my City and it stated that the city water had above standard Trihalomethanes. I was wondering if this could be causing my problems. I do run all of my water through a Reverse Osmosis and DI filter. My TDS is Zero. I'm not familiar with Trihalomethane and not sure if RO/DI is capable of removing. Thanks in advance.

An RO will take out most of that since it larger than a water molecule, and the carbon block will bind some, so I doubt that is the issue.
