Do you have any pic’s of the bag filter set-up? I’m not looking to copy your NPR system, But I am planing on adding a couple of filter socks on a new system that will have a 100gal Rubbermaid sump. My main concern is creating nitrates by using the filter socks, By using the floss & tossing it sounds like a good way to get rid of them!
BTW
Here's a denitrator made by
Aquaripure that uses Vodka to help build bacteria to reduce nitrates! I haven’t really heard anything good or bad about them, But it sounds fairly simple! Just a little on the expensive side.
I usually do a 20% WC about every 10 days (the time my top-off system needs to be refilled) which seems to be more than enough to control my nitrates! Now if the Aquaripure really helped to reduce your WC needs then I would think it would pay for it self in the savings of salt!
