I'm a little more lenient.
8.1 to 8.4
ammonia 0 - nothing else is acceptable
nitrite at 0 - see above
nitrates below 40, but for reef much lower
temp 78 -84 although some fish like it around 74'ish
I don't currently test for calcium or alk
. My Ph is very stable, so haven't felt the need.
I notice Darb2 made no mention of either henweigh or butfor.
