10 ppm's fine for most LPS and softies. If you're not seeing algae outbreaks, you're golden. Just keep it consistent.

Nope, don't dose what you don't test. Iodine can crash a tank if you overdo it. Stick to water changes for now.

You can save a ton by mixing your own saltwater instead of buying premade. I use Instant Ocean, which is cheap in bulk, and a refractometer to check salinity. Also, DIY rock structures with dry rock and epoxy cut decor costs. What's your current salt mix?
