If you reread my original post I discourage readers from using natural seawater but I realize some people still may be tempted. If your objections are based on the needless stress or deaths of some of Gods creatures I regret to inform you that our hobby needlessly stresses and eventually kills every animal collected. They all belong in the wild (most are not bred) but we ship them in bags around the world and cage them for our enjoyment where only a small percentage actually lives their full lifespan and few ever spawn. Did I mention they no long add genetic diversity to the ecosystem they were snatched from?
I worked for a marine LFS for about 20 years where our shipping loss rate averaged 3-10% but it could run as high as 50%. On rare occasions it would be 100% due to weather grounding aircraft and mind you our shipments could contain 100’s of animals in one flight. Then the survivors were sold but as you know people who know their stuff don’t buy many critters and they don’t do it often. Sadly most of any LFS stock is sold to killer customers who have a little money and less knowledge. I saw it all the time “wow these test kits are expensive, do I really need a skimmer, refractometer no my $10 hydrometer is fine” and the classic “I know you said they were incompatible but they got along fine….. for a while”. So I’m sorry if I seem callous but I guess I have a different perspective on the subject I didn’t mean to offend you by all means test your natural seawater on your DT.
say what you really mean....
first, i don't recommend collecting your own seawater....like stated above.
second, i understand alot of animals are lost due to shipping and bad husbandry. There isn't anything i can say about shipping, but when it comes to husbandry i can. Theres no reason to skimp on equipment....as well as using animals as experiments to see if water is bad or not. I agree the ocean is a much better place, but we can do as much as possible to replicate it. Without intensionally harming animals. I remember a mod here saying once that this is a site for keeping fish alive, not experimenting with them....i am an aquarist not a scientist.
third, most lfs are looking to make money....which sometimes clouds their judgment of what the should and shouldn't do. of course if i owned a bussiness i'd be out to make money to, don't get me wrong.
four, a nice conversation....no flames here.
