rapid salinity drop!?!?

[Fat Panda]

last night when topping off my tank i got distracted and forgot about it. my salinity went from 1.026 to about 1.020. within 30mins. my corals seem to be doing ok. but i have not seen my pipefish or gobies anywhere.
My LFS is closed till tomorrow at 11am. so i have no access to salt till then. will my system be ok till then? slowly raising it will be a major issue as well.

Tank 12g nano cube with 3gal fuge

I'd bring it back up over 3-4 days. Why is slowly raising it an issue?

im just afraid its too little too late. im more scared for my little reef i guess.

Whatever harm has happened already, it is still best to raise it slowly.
