Raising Salinity Level?

[mterrace]

Hi Everyone,
Currently my salinty level is at 1.023. I want to bring it up to about 1.025 - this is closer to my LFS. I have a 90 Gallon DT, and a 55 Gallon Fuge -- total is about 135-140 gallons of water.
When I do a saltwater change, I can change about 27 gallons at a time. I have been matching salinity at 1.023.
Now that I want to raise my salintiy to 1.025 -- What is the highest salinity that I should make my change water? Can I go to 1.030 for example for my made up salt water? If I change 27 gallons at 1.030, then my salinty should rise to about 1.024 in the overall tank....but will adding 1.030 shock any of my clean-up crew (Blue Leg Hermits, nassarius snails, and 2 Mexican Turbos) that I have in my fuge (this is where I do all my water changes)? Is 1.030 too much at one time....should I stay at 1.023 and just acclimate longer.
Currently I have in the display tank:
2 Percula Clowns
1 Longnose Hawkfish
1 Yellow Tang
1 Hippo Tang
1 Six Line Wrasse
1 small Leather Coral
1 Torch Coral
Amm:0, Nitrite:0, Nitrate:5, Calcium:440, pH:8.1
Thanks,
Mark

When raising salinity it should be a crawl speed, I think you should do the "TOP OFF" with your desired salinity water as apose to fresh water. 1.023 is definately to low for corals and inverts, the desired s.g. for that is 1.025-26

Just do your daily top off with salt water until you reach the salinity you wish. then go back to fresh water. Of course check salinity before and after each top off to makesure you don't over shoot you mark.

Thanks for the replies....I'll stop my automatic top-off and top off with 1.025 water.
