SRC Member zorden Posted May 7, 2010 SRC Member Share Posted May 7, 2010 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 Quote I am just an average FR (fish reefing) writer.

SRC Member comycus Posted May 7, 2010 SRC Member Share Posted May 7, 2010 My salinity probe also facing same problem. Did you check whether there are calcium deposits on the probe? Got to remember to soak mine in vinegar tonight and recallibrate it... Quote My old 3ft Link to comment Share on other sites More sharing options...
jackywongto Posted May 7, 2010 Share Posted May 7, 2010 That is quite a drastic drop Zorden. Do keep us posted when you found out the reason.

SRC Member LaW Posted May 7, 2010 SRC Member Share Posted May 7, 2010 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.
