Before I start I need some advise please. I bought 100l of already mixed water from my lfs
where I got the tank. I have poured all this into my Aquael ReefMax and it's been running now for 3 days (I have been advised to leave it 10 days). I did how ever out of interest drop a Tetratec Comfort-Hydrometer in the water just now and it's readings are
Salinity = 23
Specific Gravity = 1.017
Can I ask what it's supposed to be ideally please? I would have thought the water from the shop that they use for their tanks would have been perfect.
