bi monthly wc.. The last salinity check 2 wks ago is 1.025 ytd the reading iss 1.017. What contribute to the drop in salinity and yes. My rocks start to turn dark green.. well from white to dark green. no3 = 3 po4 = zero. some sps is suffering. kh around 7-8.

any idea what is happening. will zeovit reduce salinity or the GAC reduce it.

really too bz to take care of my tank and well... just surprised to see the drop in salinity using the electronic reader. (refractormeter loan to friend for the moment) n the difference between the 2 meter should not be that much of a diff.

pls advise. tia

salinity probe cannot be trusted at times.

If a man could beat his own fantasy. Then to only breed in captivity. Then its pointless.

Genesis 1:20

And God said, Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moves, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. And the evening and the morning were the fifth day.

very unlikely to have such a drop unless you did a major water change/top up. and you water volume is not too small. i think you better check your refractormeter. its better.
