I have a tank whose substrate is half 2-3mm gravel and half Turface MVP and
I have to add Ca and Mg to it, otherwise the hardness drops to near
zero. My tap water is very soft but I never use the stuff except to top
up. The water that's been in the tank for over a year is just fine.....
I don't believe that Turface MVP hardens water over time.
OTOH, I have had "cementing" of the MVP grains. They stick together,
probably as a result of some bacterial action. They are easily broken
apart by stiring with the finger, but......can this be good?
