Salinity levels and temperature

[tnewell]

So my tanks parameters are

ph-8.1
Ammonia-.25
No2-0
No3-0
Ppt-31.6
Temp-76.5
Calcium-is a little low

My question is, are my ppt ranges to low? I know there supposed to be 33-34 but is 31.6 acceptable to my reef tank?

I would up it slowly and also be concerned with ammonia showing. Are you cycling the tank? What test kit? Are you using a refractometer ?

I see no reason to not raise salinity by replacing evaporated water with new salt water for a few days.

I have had the tank for about 5-6 month let it cycle to first 2 months then added my cuc and my fish, a month later my coral, I did have my flame angel pass due to salinity problems. I add ro water roughly like half a gallon per 4 gallons when I do water changes, is that about the right amount?
