You know I don't know about my water anymore...I thought it was good...salinity 1.023 and all that, but when I went to the fish store it came up salinity 1.018 and PH maybe 8...I hav2 2 hydrometers, and both came out the same...I added PH 8.2, and some more salt tonight...Soooo maybe my problem is that the salinity is too low for the coral. I put the coral in my reef tank, and it already looks better....I really thought it was dead. I have 2 Instant Ocean Hydrometers...both read the same...1.023, I will test again tomorrow since I added salt tonight. Any better testers out there???
Do yourself a big favor and buy a good refractometer. They may be more expensive, but they are SO much more reliable. In a reef tank that you are adding chemicals to, you should also be testing for calcium, alkalinity, magnesium, as well as the standard ammonia, nitrite, and nitrate. I don't know what you are testing pH with, but I also recommend a good pH meter.
