I did some research and found that I could by the salt mix from my local aquarium store. The bag of salt mix would cost me about $40 for a 200 gallon mix. All I would need to do is extract water from my RO
unit into a 50 gallon container and mix the salt there.
I actually got the idea from the tech from my aquarium store. It would actually come out cheaper than buying it from the store and I wouldn't have to transport all that water when I do a water change. It seems like a good idea and I have all the equipment to do it.
I heard that the water is cleaner and provides more beneficial trace elements that regular salt water from the store.
What do you guys think?
