yes, need to add salt, after 30+ days, have to reduce the salt slowly. i am not sure the ppm of salt needed, will check it out. i went to my friend shop. he give me some sea salt, and told me that is for 4 liter of water. so i just add the salt slowly into the small tank which is about 2 liter of water. if do grow bigger. i will move them to a 4 liter tank (1 gal) and add more salt, until the salt is finished. cause i didn't buy the tester for the salt. my firned just give me the dosage to put in.
