Aquarium Advice Addict
I haven't really understood why the saltwater has to sit for 24 hours with a powerhead before use so I researched. I have been told it needs to become aerated. I googled this article Making Saltwater from what I got from it is it needs to be mixed for 24 hours because freshly mixed saltwater is somewhat caustic (corrosive I think) Like getting salt burn?? once the salt dissolves in the water its not as caustic. From what I assume. the article didn't really state anything about a powerhead for aerating the water. I was thinking I could just keep a powerhead in my RO/DI so the water was already aerated and just let the salt settle for a few hours guess not. I assume the powerhead is really for just helping to mix the salt into the water faster so that it is less caustic. . Just thinking I could mix the saltwater in the AM and do the PWC in the PM but looks like thats out of the question. Just some general thoughts about mixing water. thought I would share.
