Why Is My Salinity Rising?
G'day Guys,
I'm having trouble with my salinity. It keeps rising. My ato seems to be working fine as the water level remains constant. I tested the ro in my ato resovoir and it has a salinity of 0ppt.
I have been dosing Kent Tec M which is known to raise salinity. I haven't dosed it for 2 weeks though. I was dosing it to combat bryopsis and it is now under control. The mag level at the moment is about 1700. I plan to let it come down gradually on its own through water changes etc.
I recently started dosing Red Sea Foundation supps A and B (Calcium and Alk) using a dosing pump. The doser doses 35ml of each a day (the doser spreads out this amount over 6 dosings). I have also started using ZeoVit Start and Bak. I am dosing this very gradually.
Ok, my salinity. A few days ago, I noticed it was 37ppt, when earlier that week it was 35ppt. I use a Hanna Seawater Refractometer. I took out some saltwater and replaced it with ro. The next day it was 33ppt. After doing nothing, the next day it was 34ppt. Today it is 35ppt.
Obviously this is stressing me out and the corals. All these swings are making them quite grumpy :(.
Any ideas as to what might be going on? My first port of call is to ask Ads if I can compare refractometers with him to rule out equipment error.
Thanks guys,
Jamie.
