I have a stylo (3"), birdsnest (2"), M. spongodes (3" circle), stunner (4" diameter) and tenuis (1.5") in my small 7g tank. Everyone is doing well. I use IO reef crystals and it comes out to be 8.5dkH when fresh. I haven't been consistently checking kH because I figured frags can't be using that much kH. This weekend I added more acropora and did a kH test before the weekly water change it was about 7? Does this amount of kH drop seem normal? I suppose in a smaller tank there is less calcium by mass so maybe that is why a little growth can swing alkalinity a lot? In this case, should I start dosing 2part?
