Hi! We have converted our 30 gallon cube into a saltwater tank. It has been set up with live sand and API Quick Start for a few weeks now. I got the API Saltwater test kit today and the levels are as follows: PH: 8.1 Ammonia: .50 Nitrite: slightly above 0 but below .25 ppm Nitrate: just below 5.0 I will continue to test until ammonia and nitrite are zero but is there an estimate on how long that will take? Thank you!
