Sorry for the late reply, it's been crazy.
Just got a 20x20x20 going. Super excited. Gonna try these little Chinese pumps, see how it goes.
Here tonight to find out what is going on with my Reef Crystals. This is just not cleaning up, the precipitate is ridiculous.
I always used RC, never had an issue with left over product and it would normally dissolve fully.
Any suggestions would be appreciated and it's always appreciated saying hello
