Hello, I have read about the increase in ph due to photosynthesis. Personally when my lights go on, a few hours later the ph increases from 8.0-8.1 until about an hour after lights out. This is very predictable and constant, and my corals are growing well. So if you feel your sps are growing nicely, how many hours per day do you observe this ph increase? Thanks
