I've just had the new sump system in the basement for about ~4 months now, and I can't believe just how much is growing down there. It's like the Christians wrote, as it is above so it shall be below. I mean I have feather dusters growing in the glass, a limpit, that somehow is eating the algea in the skimmer/reactor section. Tons of pods and worms, the pineapple sponges are making a comeback. Amazing really. I'm wondering if there will be baby lighting maroon clowns in there one day.
