As title, I've got approx. 7L of used ceramic bio rings for sale. Theyre the cylindrical looking white ones.
I used them all, enough to fully fill up all 3 trays in my xp4 filter.
Took them out of my filter and they're in a zip lock bag at the moment, so they shouldn't have any bio left in them by the time they're sold.
Don't know what I'd want as a trade. But looking to sell for $30
**looking to sell all together**
