Correct. Simple way to help this is to make sure you swirl the water in a circle just before you drop the pH down. The constant movement of water helps prevent precipitation. Ya always feel bad when you see a cloudiness as you drip the pH down. That's all ya stuff falling out of solution

Yeah all I have is a single 4 inch airstone in my 5 gallon coco dtw test bucket. It stays very stable since nothing is eating it. 6.2 for days

I was not liking the swings with RO so I started to use tap water or a mix of 70% RO 30% tap. the alkalinity/hardness will keep it much more stable. For the tap water I use a hot tub garden hose filter or i bypass the RO Membrane and just use the water that comes from the sediment/charcoal filters.
What is the PPM of the tap water you have?
