Anyway there is no skimmer who can skims everything out of the water and IMO, the skimmer only helps to a certain extent of removing nitrates.
And really appreciate if someone can let us know if there's one skimmer who can sucks all or 90% of the DOC so that all reefers who are using the denitrator can lelong or have a garage or garang guni sales
No more worries about Nitrates
