topping up with premixed salt water until you get it up to your target range is the best way
You can raise a sea urchin in a salt-water aquarium. There are no fresh water sea urchins so you would need a salt-water aquarium to properly care for the urchin.
yes, evaporation raises salinity because salt doesnt evaporate like water
you can, it can be any salt dissolved in water, including sodium chloride
The typical salinity level in a saltwater aquarium is around 1.025, which means there is about 35 grams of salt per liter of water. This salinity level is crucial for the health of marine organisms as it helps maintain the proper balance of ions within their bodies. It's important to regularly test and adjust the salinity level to ensure the well-being of the aquarium inhabitants.
No. Also, do not use table salt or aquarium salt -- use an artificial seawater mix such as Instant Ocean. Seawater has a lot more in it than just salt! Saltwater snails like Astrea require a specific gravity (salinity) of 1.024 to 1.026. You can buy a hydrometer at most retail pet stores that sell fish/supplies, or online, to test the salinity when making saltwater from a mix. You should also test the salinity of your aquarium periodically. Snails are very sensitive to rapid changes in salinity, so you should frequently replace water in your aquarium lost to evaporation. Letting too much evaporate for too long and then dumping in a bunch of replacement water can send snails into shock or even kill them.
Salinity usually refers to the percentage of dissolved salt in water. A salinity meter simply measures this. 3.5% salinity = 35g of salt/Litre (this is your average salt water)
Aquarium salt can be used as a medication for certain illnesses of tropical fish including guppies, and used at the correct concentrations for a specified time, it could help a guppy get better from its illness. If on the other hand, if salt is just added to the water for no specific reason then at low concentrations it will do very little harm. At higher concentrations it could well kill guppies.
You need to purchase a salt mix and add water. Then mix overnight and check the salinity the next day. You want it between 1020 and 1025. Also, make sure the water is the same temp as the aquarium. You may need a little heater in the salt water you are mixing.
i believe it is salinity
Salinity is the measure of salt concentration in water
Salinity is the amount of salt in something. So, "dry land salinity" is the amount of salt in the dry land involved.
Salinity is a measure of thew salt content in a solution and is expressed in parts per thousand (ppt)
