hi yoyoyoo, first off, I really appologize for the low level on the saltwater that you have purchased. I always use a refractometer to check the salinity after i mix the salt water in our store bin, I also have a salinity meter that is on that tub. I realized the same issue last night when i was closing and glanced at the salinity meter and it was reading alittle low.. 1.019! I was like huh? and then i found out that my store employee had took about 100 gallon of saltwater the day before (when i was not in the store, I was attending a business matter) and refilled my tank with RO but only had added one bag of salt (50 gallon mix) and not realizing that my RO system does at least 100 gallon per day. Therefore, there is a problem. Also i was upset that he didnt tell me in advance, I NEVER sell fresh mixed saltwater, I always let it settle and mixed for at least 24 hours before it it for sale, to make sure all the salinity level and PH are correct. I even turn my customers away becuase of the new mixed saltwater.
Again, I really appologize for this and not knowing in advance to warn you. Afterall, it is my fault and i will be glad to replace 5 more gallon of SW for you for free the next time you come in. Please just mention this to me. Thanks again for the support and believe me, this is not intentional. I am not trying to save on salt, if you look in my store, what do I have the most?? its the salt..lol
oh, for those that doesn't know, I use nothing but OceanPure PRO salt for my saltwater, and so far, it has been great for all my customers's tanks.
