OK my tank is fully cycled, about 3 wks old, all levels are 0, so I'm ready for some fish! I've read enough on this forum about the use of a qt
, so I'm of course going to go that route for any new fish that I add.
I have an old 10g fw
tank and Whisper "Advanced" 10-20g hob
Power Filter (Tetra) that I was going to use for my qt
What I'm not sure about
1. People keep talking about a "sponge filter"...what the heck is that? Can someone provide a link to an actual sponge filter product? The Whisper filter I have includes something they call "bio foam", through which water can flow and bacteria can build and develop. I suspect that might serve the same purpose as a "sponge filter" - I think I can place this bio foam stuff in my existing display tank filter, so it will collect some beneficial bacteria, before putting in my qt
. Is that right? Or should I scrap this hob
and just get a sponge filter?
2. Should I put water in the qt
from my existing display tank, or new saltwater? A mix? I'm thinking I can put water in my tank as I do water changes from my display tank?
