??? I'm not sure what you mean?Whatever is cheapest and easiest. NSW springs to mind :)
lol sorry I'm a bit of a newbie to this. Only my 2nd tank. I was thinking of going natural but I can't be sure there are no contaminantsMy bad, NSW = Natural Salt Water :)
Thats so true, my LFS sells NSW dirt cheap and always excellent quality but I enjoy going out in the morning sunshine to get my NSW. (which tests the same as what I can buy.)Also - depending on where you are located, there are lots of LFS's that sell NSW and even people that will deliver it. Just makes it all too easy :)
