Those of you with good memory might remember this LARGE piece of schedule 80 gray pvc. It was originally painted in black plasti-dip but peeled some after the synos kept rasping on it. This also was used as a cave for my chocolate Bobo!
It's not quite where I want it...needs a bit more work with shadings. If you want to spend the money, large diameter pvc is the way to go for really big fish. I prefer the gray because you need far less paint/surface deco and the darker interior is more natural to the fish (looks better in the tank too). A lot pricier than the pvc 40 at large sizes though but a nice splurge if you have a big cichlid that loves caves. Interior diameter on this is 6 inches, length a foot.
As soon as I glue the intake stems on the powerheads the filters will be ready for testing. If I can fit a heater in the tops I'll do that too.
