salanity

new to the hobby. have a 13.5 fluval mini tank. with a couple clowns and some zoa. nothing crazy. I try to maintain 1.024 and check almost daily after 6 months from new. now im noticing that my salinity creeps up to 1.030 very quickly sometimes within a few days. using a refractometer that is...

My tank is at 31 ppm right now. I’ve been trying to get it to 35. The salinity was at 33 Sunday. And I did a water change Sunday with buckets at 34. I’m very confused how on it dropping. I use a refractometer And i calibrate it. Plz help.

Opened, used once or twice, basically new. $35 shipped from upstate NY.

Neptune Salinity - Conductivity Probe - Lab Grade

My Salinity is at 31ppt. In theory could I just use salt water in my auto top up to increase my Sailinity. Will this cause my any problems? Any alternative methods?

I ran out of RO water cleaning my tank and was wandering if I could run it under tap to clean off all the salt water. Thanks in advance!

So I just picked up more salt and RO/DI water at my LFS. I checked the salinity with my refractometer and it said it was 1.030, they told me it was 1.025. They used a very expensive salinity checker so I’m assuming there’s is more accurate then mine, so the problem is the salinity of my tank...

Brand new never used ended up going with a Milwaukee instead. Asking 40.00
