sg question.

[FLOEDOG]

Need A Little Help, I Am Now To The Point Where I Can Start Introducing Some Coral To My Tank But My Sg Is 1.027(which Is To High), I Will Be Geting My Coral From Dr Fosters & Smith.com And I Know They Keep Theres At 1.025. What Is The Correct Way To Lower It Without Hurting The Clean Up Crew Or Damsel In The Tank? Someone Help Please...

Flo,

few questions -

What size tank/system volume?
Are you using an auto top off system?
What inverts?

Generally speaking, I would take 8oz out a day for the next few days and let the ATO put fresh RO DI and let it decrease slowly over time.

Take some water out of the tank. Use some airline or an ATOP and drip in freshwater (no salt). You're really not that bad SG-wise. Salinity varies a little in the ocean. I'd gradually lower it down to 1.025, but 1.027 shouldn't hurt the corals if you acclimate them slowly (about a 2 hour drip should do it depending on the SG of your tank and the water the corals are in.)
