Filtration

I have a IM 30L. Currently running just skimmer and bioblocks. Tank is doing better. Can I continue this without using purigen and chemi pure like I was before?

You dont need to constantly run nutrient sinks in a tank unless you have an issue.
But keep an eye on nitrate and phosphate that they dont creep up on you and run nutrient export methods as needed.

Understood. That’s why I had zeros for phosphate and nitrate

Then yes you should be just fine to keep them removed. But just keep an eye on those numbers creeping up again.

Chemipure elite and blue long term can zero out your nutrients. Added skimmer further does this. best bet - run skimmer without media Unless an elevated issue should arise.
