I have been using my refractometer to measure my salinity, and I have been reading it as 1.025. Today I decided to test with the hydrometer, and it reads 1.023. The tank .

The directions say to calibrate them with RO water and turn the screw to 0 while the RO is on the reader. I did that and still got 1.013 for the new ones and 1.023 for the old After calibrating my salinity of the tank was 1.023 and before it was reading 1.026 / 1.025. I panicked and grabbed my refractometer which reads 1.025 on the tank so I was like . 1.026 is natural sea water, so in theory 1.030 is a bit too high...however, as said, for your water change, dilute it down to 1.024. if you want to build yours up a bit to 1.026, you should do it slowly.. the other thing to take into account is how you're measuring it. i originally used a 'swing arm' to test salinity and it was always showing 1.026 then when i got the .

Refractometers And Salinity Measurement Salinity is one of the most important parameters measured in reef aquaria. . I didn't know if that is an issue. It's the difference from my tank reading 1.025 or 1.023 ;p . Reply. Aug .This dual scale salinity refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. Measures Specific Gravity from 1.0 to 1.070. . Once a .
The direct calculation from Salinity (‰ - ppt) to Density (g/l or kg/m3) / Specific Gravity is based on the equation adopted by UNESCO - The One Atmosphere International Equation of the State of Seawater (Millero and Poisson, 1981). Now, for a salt water aquarium at 20 deg C, the refractometer works well, because the target is in the 3.1 to 3.8% range, and the specific gravity would be 1.023 to 1.028, and that is easy to measure. For salt concentrations that are relevant for freshwater fish, you really need a digital salt meter. Buy Milwaukee MA887 Digital Salinity Refractometer with Automatic Temperature Compensation, Yellow LED, 0 to 50 PSU, +/-2 PSU Accuracy, 1 PSU Resolution (color may vary): Refractometers - Amazon.com FREE DELIVERY possible on eligible purchases . Customers also say the digital reading gives them a perfectly straight line across . The glass tube floats at a certain depth based on the salinity of the water. Water density increases with salinity causing the glass hydrometer to float higher in the water. You then read the salinity using Specific Gravity (SG) at the waterline where it lines up on the scale. Seawater at 1.026 equates to 35 PPT.

I noticed today when I checked my Salinity, that it had dropped significantly from 1.025 to 1.022-1.023. Any good way to get it up? What some water (1/2g-1g) with a high salinity and pouring that into the display? Also, if anyone some premade saltwater or if anyone has some extra salt laying around I'd love to get it from you. Thanks!-Brooks
I did a search on the forum, but still not sure about how to raise the salinity in a safe manner - right now, it's at 1.023, and I'd like to get closer to 1.025 In order to do so, I"m assuming that I need to create a bucket of saltwater at 1.025 - what's the best way to raise the existing 1.023 to 1.025? Also, when I'm taking the readings with a refractometer why does it .
It’s pretty simple – if the water salinity is too far out of your fish’s comfort zone, it can cause stress or even death. . Look through the eyepiece and note the reading. Adjust the refractometer if it’s not showing 34 to 36 PPT. Clean and .
I just received a brand new Milwaukee refractometer and the reading for the standard solution is off. The standard is 1.025, but reading is coming in at 1.023 no matter how many times repeat and/or recalibrate. . Can I get some help with my salinity issues with new salt water? cybrook1421; Aug 18, 2024; Reef Chemistry by Randy Holmes-Farley . A refractometer is likely a better choice than a hydrometer. Before the hydrometer crowd jumps in and claims that you can get perfectly good results using a hydrometer too, yes, that's also accurate. In terms of usability and precision, I think that refractometers have an edge over hydrometers. Having said that, I wouldn't go with a refractometer.Replenish evaporated water with clean freshwater - not prepared salt water. Remember, salts remain behind after water evaporates. If you top off your aquarium with salt water, you are compounding salt levels in your aquarium. Before using a new swing-arm hydrometer, condition or season the hydrometer by soaking it in saltwater for 24 hours. Once calibrated, use the refractometer to measure the salinity of your aquarium water by placing a few drops onto the prism and reading the scale. 9. After each use, rinse the refractometer with distilled water to remove any salt residue and dry it thoroughly before storing. Regular calibration is recommended to maintain accurate readings.
Remove a bit of salt water from your aquarium and leave it sitting for a few minutes so that both the water and the refractometer are the same temperature. Drop a few drops of saltwater onto the prism, make sure surface is . Ensure that your equipment is reading correctly and your aquarium is at the right salinity with Tropic Marin's High Precision Hydrometer. Many tank inhabitants are sensitive even to minor changes of the water conditions. Unfortunately as we've all experienced, salinity reading equipment as.
I just bought a Hanna salinity checker and checked both the water I was mixing and the tank water. For a while I’ve been using a secondhand refractometer, which I’ve never calibrated myself (rookie mistake, I know). . The Milwaukee Instruments digital salinity refractometer is ideal for saltwater aquarium professionals and enthusiasts. . (20/20) | ±0.3°C / ±0.5°F Thus, if the true value is sg = 1.025, Milwaukee claims the reading will be 1.023 to 1.027 . Reply. Reactions: vetteguy53081. Sep 3, 2023 . I have one which consistently reads 1.028 on water .
Almost all of the refractometers hobbyists typically use have a stated accuracy of +/- 0.001 sg — so a reading of 1.025 means only that the actual salinity is anywhere from 1.024 to 1.026. Reply Reactions: saltyhog , X-37B and LiamPM Not sure if this is because it’s new. But when I measure my salinity last night it was at 1.023. Now I measured it today and it’s right under 1.029. . Yep I have 30 gallons of Rodi water ready to use. . If you can rule that out then I would look at ensuring that the surface of the refractometer is clean of dried salt and that you . 1 - take your refractometer to a few LFS, and start measuring their SG/Salinity (BTW - measure in ppt [salinity] not SG) 2 - start mixing some marine salt with the LFS water to bring it up to your tank. You need 1 gram for every litre to raise salinity by 1ppt 3 - [preferred] RODI water, and mix your own to a known salinity, removing all doubt.
When using a conventional ‘saltwater’ or ‘brine’ refractometer for the reef aquarium we must therefore look to achieve a reading of 36.8ppt if our intended salinity is 35ppt or 37.3ppt if our intended salinity is 35.5ppt as quoted for the H2Ocean salt. CALIBRATION

So, I originally had a refractometer reading 1.023 on my refractometer. I decided to get a new one as a backup in case so I can compare them. I ended up getting a brand new one that read 1.013. I returned it for another one, but that . I calibrate mine with quality RO/DI from my lfs which is where i buy the majority of my corals and saltwater from! They typically Keep their sg/salinity ~1.024/33ppt according to my refractometer.. And have great success So for my purposes of keeping my salinity consistent at that level with my ato regardless its .01 or so off works well! How much does temp effect the reading anyways? Are we talking about shrink on plastic parts that tiny? . non-damaged refractometers, RO/DI water is a sufficient calibration fluid. Now if you dropped it or suspect something isn't right, then invest in a calibration fluid. Or make your own (35 grams NaCl into 1 liter DI water = 35 ppt saltwater . So, I started with my tank at 1.025, and after reading several threads, saw at least most people posting were running 1.026. I'm wondering if there is any 'real' noticeable difference between the two levels, and if there's any benefits (besides cost of salt) to moving between 1.024-1.026? . Salt & Water Salinity Drop? By MizTanks in forum .
Replace your saltwater with freshwater gradually over the course of a few days, and measure the salinity with every water change using a refractometer. . where it rains a lot, the salinity levels in seawater are lower. The freshwater from the rain dilutes the salt water, therefore the reduced salinity. The ocean water around the Arctic, or .
