Someone told me I have to use RO water and synthetic sea salt to mix saltwater. Is it true?
Can I just use water conditioner to make tap water safe, then use it to mix saltwater?
What are the pro and con on each way to mix salt water?
Thanks.
You should use RO water, not tap water. Tap water can contain heavy metals and nutrients that fuel algae growth. A tap water conditioner doesn't remove these things. You can buy your own RODI unit for $125 to $150, and it plumbs in under your sink. If you don't want to make your own RODI water, you can buy it bottled at the grocery store or Walmart.

This is the one that was recommended to me. I have it plumbed in to the washer hose instead of the sink but it works the same.
