Ok lights and temp look real good. PH on the other hand, 6.5 is the highest you really want to go. 5.5-6.2 is average. Take a sample of your water to someplace like Petco to have it tested and it is free! They should be able to tell you what the water is like when it comes out the tap. PPM's and PH are the main 2. Also do you use Calmag by chance?? Lastly a pic or 2 would be great.
