Hi, and welcome!!

I would recommend that you go ahead and get your test kits, and run a set of tests on your fill water andpost them here. That will help determine what you'll need in the way of chems. We know you'll need bleach and muriatic acid (the latter because you'll have a swcg). The rest will depend on your water. The bleach canbe plain, generic-- lots of us use generic ultra from wal-mart. As for the equipment questions, I'll leave that up to the others.
