Ok....I might be a little late with this but...
You read & ask but do you take advice that is given?
No-one said or indicated that you can't ask questions, but what I take from this is thread is that you are trying to cut corners in a hobby that you can't.
Your genuine concern is not about the ingredients of table salt or snow salt as to "can I use it since it's cheaper that synthetic sea salt."
There were links provided in this thread as well as you previous threads regarding basic saltwater 101.
Take a second to learn them, price out your items, figure out if you can dedicate the time & if this is the hobby for you.
When you start disregarding the basics & try to take short-cuts....you have to expect the "not so happy post."
Alot of this hobby begins with common sense after you research.
Take it on your own to do it. You can't just ask questions & expect to hear the answers you want. Members are not always correct.
What we see here are alot of people "asking" but never taking the correct advice given.....to come back & post "why is this happening to my tank / livestock."
Get uptight all you want & say peeps don't want to help....but members gave advice here, as well as all your other threads. Some keep it straight to the point because that's how some "listen".
Take it for what it's worth.
& remember:
& thanks for learning something about me. Might be one of the reasons I became a mod.
