I grabbed a pack of the glow-in-the-dark ceramic moonstone that Wal-mart carries today!
Wanted to check them out, and saw an old, old thread that said they were working out well! From multiple people, no chipping of bubbling in the paint and stuff.
Are they still a good quality item..?
I have a 5.5 gallon tank and a aqueon internal at10 filter. I also have a box of bioballs and a box of ceramic biomax rings. how many pieces of media should I put in this small filter for a 5.5 gallon?
