Welcome to the forum!
You might also want to test your tap water, great for knowing where you stand. If you dont' have a test kit I would highly recommend that be at the top of your list. Test tube liquid tests, not the strips. (known to be in accurate)
I use my tap water for my cichlid tank and ro
water for my SW
setup. Whe I can afford an ro
unit I will prob use that for everyones tank.
Did you cycle your tank yet? If not this is a great place to read up.
Either way, welcome and load up some pictures! We love pictures here!
