Newbie Needs Advise On What Fish To Keep And How Many

[This Old Spouse]

This Old Spouse is a take on This Old House, because we're always buying run-down houses and restoring them. Not to mention I'm old!

And no, if you donate 1/3 of your media you'll be fine. Just be sure to put a full size new media replacement in with the 2/3 you still have so it gets seeded and will be ready to go by the time the 2/3 is falling apart.

I have old media in with the new whenever I know I'll need it. With my HOB filters, I just stuff the disintegrating floss into a nice new bag. Never had a problem.
