Hi there all that read this.
well iv been keeping a salt water tank, for almost a year now, and i have been collecting my water direct from the sea. this seems to work sofar. but on occasion i find the need to mix up salt water, using tap water, declorinator , and red sea or aqua one salt. but it is sooooo expensive to buy salt its not funny.around 100 to 180$ for 20 kg, wich makes about 600ltrs.
my question is this. in september this year, i will be driving past a place called Cargal salts. they have massive drying ponds and stockpiles of pure sea salt. and its all free, would this salt do the job.
any help or futher imfomation would be greatly appreciated.......
