It't very important to use the powerfilter in conjuction with carbon dosing to get the maximum result.
I have finetuned this method and defined a standaard with the dosings so users have a higher chance of succes.
When all rules are followed as laid out in the DSR basics, the omissions of the skimmer can be permanently. Just like i have been doing since 2019 with all of my tanks.
