adding water

I always hear that when water evaporates, you just need to add
unsalted water, since the salt is still in the tank. I don't do this,
I always add salt, and my salinity is pretty constant. I do have lots
of salt up around my light and on the top edges of the tank. Why is
this?

surprised your salinity stays constant,try differant hydrometer.you should
really only use ro or di water for your top ups,as to the "salt creep"
around your lights it could be you have a lot of surface movement causing
the water to splash up,try raising your lights to say 6-8inches from
surface.
hope this helps

Dear Tom
You should not add sal****er! Just plain water.
If you tell the size of your aquarium and how much water to add dayly I can
tell you how long it will take until the content of salt in your aquarium
doubles.

Personally, I believe that when the salinity is highly excessive, it builds
up on the exterior much more readily and with more mass. I usually just add
pure water, and then monitor the hydrometer readings to ensurew that i
maintain adequate salt levels. Mike.

This is true. Use RI/DO water or distilled.

It's called 'salt creep'. And is giving you a false reading + it will
eventually kill your equiptment. Clean it all off with tap water. You
woun't like it when/if a chunk of it drops off into your tank.

Also clean your SG meter (the swing arm type) with vinegar to clean
it.
