Octo 1000 hob skimmer question

[swoons]

trying to setup my hob and I’m wondering to fill the skimmer up to get it going should I use tank water or fresh rodi water? I don’t want to use so much tank water that it’s gonna lower my levels

Tank water. Make some more saltwater up first

Agreed. Has anyone with this skimmer used the return chamber for a mini refugium? I'm going to add macro algea and may be small rock. Wondering if there are any problems with doing this.

Thanks
