I have 5 tanks running and used at least 2 full boxes of the Turkey ones that were replaced. I never saw any I’ll effects on any of my tanks. I was close to panicking and doing massive water changes that would likely have caused some issues. Instead I just kept an eye on everything and no noticeable issues. Even if I would have had some sort of issues it would have been hard to finger point at the salt. I’m always changing something as I continue to learn from the hobby and what works and what doesn’t. i can’t help but wonder how many people are like me making changes a lot and read about the salt issue and just automatically blamed the salt for any issues.
