1. can use treated tap, not ideal in the long run but think about a ro/di in the future.
2. Ammonia, water changes, time and don't add anymore livestock.
3. pH, raise salinity good aeration, but wouldn't worry to much
4. I drip for shrimp, some corals but for fish, add water by the cup, works
5. If it a marine salt, again wouldn't worry, Sifto or water softener be concerned
6. I started with Hagen, but moved to Saifert as found easier. Numbers between the kits really weren't too for off from each other. For pH I had to give up on the test kits and got a meter.
7. salinity 1.026 is the ideal and a lot depends on the method of testing, found my swing arm one day was good, next day was toast against a refractometer.
Anyway here's values to go for
NSW. Also not knocking Canreef members and everything here is good advice but remember we have the same range of experience as LFS employees.
Relaxing hobbie eh?
