I'm just about to start my QT
again in a few days - I'm using 2 foam filter pads for my Fluval 2 Plus (internal), which have been in my main tank for 2 weeks seeding.
is 15 gallons, and I'm not using any substrate.
All I put in there last time was a black mug for the fish to hide in (also covered the sides/back/bottom with black card).
But, this time I'm wanting to put something in to help the bacteria cling to, as there'll be no rock etc.
What would you recommend to put in there to help the bacteria?
