You will most commonly see salinity measured in parts per thousand (PPT or ‰). And here is where it gets a little bit confusing. Analog refractometers require a bit of tweaking to get precise measurements, but not so much that a beginner can’t figure it out. Now as you might have guessed, this is an awful lot of work for the average hobbyist, who just wants to raise happy and healthy fish…. fish do better at a slightly lower salinity, and it does lower the risk of diesiese related to fish.

But did you know that fish need the ideal “saltiness” to survive? To correctly measure the salinity, you need to take a precise weight of seawater, evaporate the water and measure the weight of the residue left behind. Together these two ions give seawater its “salty” taste and account for 85% of all dissolved ions in seawater.[2]. You know that crusty salt buildup on the edge of your tank?

The idea is to get the salinity as close to the salinity in your tank as possible, assuming the salinity of your tank is correct. If you then boil that water until it evaporates, a salt residue will be left behind. Your email address will not be published. Over time, this loss of salt can lead to reduced salinity. Keep it simple, roomy, stable, clean, natural. These range from small pen testers and handheld units for occasional salinity tests to automated systems that continuously monitor the salinity and alert you if it is above or below your preferred level. I go with the Apex probe and once a week during water changes, double check with a refractometer to ensure the probe isn’t drifting.

So before I add my saltwater mix to the tank, I test the salinity level of my mix and adjust it if needed. The generally accepted salinity of natural seawater is 35 PPT. When many people are considering setting up there first marine aquarium, they can develop a perception that water chemistry (parameters) in a salt water environment is a complex topic.In my experience, … The most common cause of fluctuating salinity levels is user error.

But if your tank contains plants, corals and critters like sea stars that are highly sensitive to changes in salinity, then I recommend skipping this option. salt per kg water) seems to be the standard that most of us are trying .
