Well, it's really a hard hard works for me coz I'm not a good student since young and not even have a single memory about chemical knowledge.
Anyway, right after I make the decision, I start working on a lot of research, and facilities to get. As here is a small town there's only a very old aquarium fish shop and their things is full of dust. I got my guppy there as well.
I can't find any helps in there coz after the boss knows I would like to start a salt water tank, she give lots of bad comments about having a saltwater tank. It's just impossible to maintain a saltwater tank. It's smelly and messy and lots of never end problem.
I think she is a very honors person. Because she is telling the true tat she feel about saltwater tank details! Haha...
So at the end I still bought some left over salt water facility she got. And hope from there I can do my best to avoid the bad circumstances tat she told me.
