Would anyone be interested in seeded aquarium sponge?

I bought a seeded sponge from Angels Plus, and because they have a minimum purchase amount, I ended up with WAY more sponge than I needed. I was like, "Wow, this box is pretty big. Wow, this box is pretty heavy."

As you can see by the pictures, it is much much larger than my filter sponge. I hacked a chunk out, shoved it in my filter, and literally just plopped the rest of the thing in my (unoccupied) tank to keep it wet. I kinda panicked and I didn't know what else to do. It also came with a blue tube and has some sort of like glass bulbs in the middle of it. I have no experience with sponge filters so that's all foreign to me.

SO. I need to get rid of this thing obviously. I could just throw it away, but that's such a waste of perfectly good bacteria. If anyone wants some good bacteria to speed up a cycle, here you are. I'm really not sure how much to charge for these things. On the one hand, it has some value because it speeds up the cycle. On the other hand, it's a wet piece of sponge. We'll start at $4 + shipping but that can change based on the size you need and how much shipping is. If shipping to where you live is high I'll have mercy on you.

PM me if you're interested and we'll figure out how much shipping is and how much sponge you need. This will be my first time shipping anything 'live' so have patience with my ignorance.

Thanks you!
