the white PVC is a piece i made and put over it so the was could drain into a filter sock to reduce microbubbles. the pvc comes off and i dont have the sponge the goes over the exit pipe. so thats why i used the pvc which works great.
all the rock and livestock are sold. im selling the tank, light, stand, return pump, skimmer for $300. which is a steal because i bought the 250 watt pendant for 300 and i put a new bulb in it last month which cost 69.99.
