salanity

Hey All - so relatively new (4 months in) and my tanks been doing fine. A few days ago I noticed the corals all didn’t seem to be doing well (not expanding) so I did a water change with LFS reef crystal pre mixed water. Still didn’t help. I do regular water changes so never really needed a...

Hi guys, I am in the process of filling up my tank for the first time. I managed to produce around 100 liters of RODI water (it's pretty slow) into a 140-liter container. Last night, I decided to add the salt so it could dissolve overnight. This way, I can add my live sand and the water to the...

I have a 20g saltwater aquiarium. No sump, but a nano skimmer. And I came across the reef pi and thought it could greatly improve the stability. I've seen people build ATO, but none of the ones you can buy off the shelf seem to include salinity measurement, and I feel like that would be a major...

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
