Another question. Probably frequently asked but i cant find the answer anywhere... Can i dry seawater to make my own salt? Is sea salt ok to use in the aquarium? Its not the normal table salt im talking about .
dry seawater to make your own salt. You will be also taking all the fine particulates and other things that reside in your local seawater. I think it would be a process that wouldn't provide a good yield for the work involved. Why evaporate a 5 gallon container of salt to have enough salt to make 5 gallons of seawater?
As far as the "Sea Salt" that you buy in your grocery store for cooking. I do not think that it is a problem, but it usually is a lot more coarse than the salt you buy at your LFS and could be harder to dissolve. Plus you would have to be absolutely sure that there is no metal content (like from the process of turning it from seawater to salt).
Any reason you don't want to just use the "Instant Ocean" or "Brightwell Aquatics" ready-use salt?
