can you use kitchen sea salt in an aquarium?
Nope, you have to buy special aquarium salt which is expensive.
Actually, real sea salt should work, as it is simply evaporated sea water. That being said, I can get a bag of Instant Ocean for the same amount that I pay for a small container of quality sea salt. Morton and the other food salt companies have to pay more to insure that their facilities are rated to produce food-grade products. There's less control on aquarium products, which means less production cost. In the end, the cost to make marine water with food-grade sea salt would likely be prohibitive, and pointless, since you can get marine mix for much cheaper. Edit: I forgot to mention; there is more to making marine water than just adding some salt. You need to have a refractometer or other method of measuring salinity, so that you can get the correct amount of salt.
As long as it is real sea salt, it will be ok. Note however, that there is more to the salt mix than just salt. If you are running or going to run a reef, I would not recomend it at all. If you are doing fish only tank, than it might be ok, but you will have to deal with pH, and Alkailnity, and other stuff that is automatically incorporated into the design of the salt mix, buffers additives are already in the mix. Also as mentioned above the cost might not be really that big of a difference to justify using it.
dont do it buy some salt its not that expencive
freshwater fish dont need salt
*whispers* Shawnie, this is in the saltwater forum..Unless you're saying freshwater are better, and don't bother with salties.
ooops....ty meenu :;laughing whispers back"what a brunette moment for me again! " LOL didnt know wonton was doing a salty tank ;D
Also remember, that a lot of Kitchen/Table salt, whilst 'brewed' by evaporating sea water, it also contains anti-caking agents, thus no good for aquariums.
and most people by iodized salt...if you must, at least get pure salt.
Both excellent points. I forgot about those, because I buy pure sea salt (there is nothing in it but evaporated sea water, containing all of the trace minerals you'd find in the sea it came from). I forget that Morton makes sea salt, as do a number of other brands, and they use varying levels of additives to make their products more "consumer friendly."
