Ok. Yea. I did test everything was ok. I noticed tonight my new hornets look kinda ticked. So my salinity is now low. Like 1.024. why? I'm not sure. Can anybody explain please?
 
How are you topping off? Are you using a refractometer? The reading will change with temperature changes.
And that large a swing shouldn't be bad.

Tank temp will also change salinity as well.
 
How will temp change salinity? It has been hot the last few days. The tank is beside of a window.
 
Lol.
Don't sweat it. Probaly just the zoas messing with you.

Go have fun. I'll post stuff for ya to read later.
 
My dinner guest is a very old friend. She is laughing because I'm stressed. I actually even cooked. And thanks for the hand holding. Much appreciated.
 
No worries. It's probably nothing.

One of the only really good looking zoas I own(blue ones) have been messing with me for three days.
I took them out and punched them.



Ignore this till later.
In short, salinity is effected by density. As temperatures change water density changes ( molecules expand retract), and and the salts are basicly squeezed.
