- 1. 025 vs 35 ppt - often used interchangeably? | Reef2Reef
I rejoined the hobby back ~2016, and everyone seemed to agree that 1 025 was the perfect salinity Lately though, more and more I've been hearing that 35 ppt is what you should target for mixed reef or SPS dom It's strange to me that these are often used interchangeably, since 1 025 is really
- Four Salinity Testers, Four DIFFERENT results - Which do you trust . . .
I tested water in two of my reef tanks and got four different results from each - See Photo Which do you trust and what do YOU Use? 1 Salinity Refractometer for Seawater (calibrated) 2 Instant Ocean 10+ years old 3 hygger Salinity Tester 4 Coralife Aquarium Fish Tank Deep Six Hydrometer
- Ideal Salinity | Reef2Reef
What is your ideal salinity My tank is at 79 degrees F and has a specific gravity of 1 022 I read in ppt that that equates 31 6 ppt salinity What is the ideal range you guys have success with??
- Formula for salinity correction | Reef2Reef
Have you ever tested your tank salinity and found it to be too high or too low? I know I have I hated guessing what salinity water I had to use to increase or decrease my salinity to the desired level Well guess no longer, friend I'm sure this formula is used for other things, but I figured
- Specific Gravity vs PPT | Reef2Reef
For reference, natural ocean water has an average salinity of about 35 ppt, corresponding to a specific gravity of about 1 0264 and a conductivity of 53 mS cm It often ranges from 34-36 ppt over reefs, but can be higher or lower locally for various reasons such as land run off of fresh water, or evaporation from a lagoon
- Salinity - PSU vs PPT | Reef2Reef
An older salinity scale is ppt (10-3), where salinity is defined by “the salt content is the weight of the inorganic salts contained in 1 kg of seawater if all bromide and iodide are replaced by an equivalent amount of oxides” (Knudsen, 1901) In summary, I should aim for a PSU of 35 (vs 35 PPT)
- Refractometers And Salinity Measurement | Reef2Reef
Reef aquarists monitor salinity in a variety of ways, including specific gravity measurement using hydrometers, conductivity measurement using electronic meters, and refractive index measurement using refractometers Refractometers can be a very good way to measure salinity, assuming they are appropriately designed and properly calibrated
- Reef Aquarium Salinity: DIY Calibration Standards
General Salinity Discussion As far as I know, there is little evidence that keeping a coral reef aquarium at anything other than a natural salinity level is preferable It appears to be common practice to keep marine fish, and in many cases reef aquaria, at somewhat lower than natural salinity levels This practice stems, at least in part, from the belief that fish are less stressed at reduced
