	true de-ionizer but couldn't find any doc about it :( [JMS]

	Sure !, it's just like RO, you could just use it to dilute, not

	degrees, sorry[JMS]

	Yep, it was what I was doing when I was so surprised with the
reaction of my rams.Their beating (ventilating?) quickly with what should be
their arms if they were humans and just stay in a corner, loose their color.
	Those who survived get their color back but are quite "quiet", not
the cichlidish attitude they used to, and still ventilating quite fast.
	There is a good water flow and enough ventilated and it's a specific
tank, not overpopulated (about 30liters/ram)[JMS]
