Salinity test wack

[Spenc_]

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, with my refactometer it says it’s 1.026. I don’t have corrals, nor fish. I only have two toures snails and a hermit crab.

Should I set my refractometer to the LFS water? I calibrated my refractometer with a solution I bought off Amazon and it said to calibrate it to 35ppt. Did I calibrate my refractometer wrong? This is probably the most confusing thing I’ve done so far with my tank.

Thanks in advanced <3

Did you calculate it again before use? I would trust my own test over the lfs

Idk i make my own for this very reason.

I did double check, should I throw some RO/DI water on it and make sure it’s 0 then check it with the solution again to make sure it’s at 35ppt.

I have been making my own as well, thought I’d just buy some instead. I follow the instructions on it and mix 1/2 cup with a gallon of water. How much does the temperature affect the reading?

I dont follow the directions anymor. It is a feel. I know to test when it starts to get murky. Lol or cloudy.
Thats good that you can make your own. I would test rodi water. Get 0. Test my tank. Adjust my new sw and than do my wc. Most refractometers come with atc now. Auto temp change. I think thats what atc is. Lol. Change or controller. Lol!

Yea no fish yet, been running for like 6-8 months now. Wanted to get everything else down before I threw in fish as they’re not cheap lol.

No, don't do that. Refractometers drift, and some people calibrate their every time they use it. I think that's a bit much, but do calibrate mine with 35ppt solution every week.

After many, many dumb errors, I also bought glass hydrometers, inlcuding one from Tropic Marin, thanks to [HASH=37961]#reefinmike[/HASH] . They're big and bulky and awkward to use (they really do need to be put into a graduated cylinder or some type of flask for an accurate reading), but they never drift and never need to be calibrated. Best thing I ever did for my tanks.

Blow your.rock off with a good turkey baster bro. Do a wc and add some fish and nice size clean up crew. They have 6 to 8 months of catching up to do. I add fish before cuc. Thats just me though. U got this!

I added fish after four days they are doing great three days after using turbo start.
