I am about to redo all of my plumbing on my reef tank. I was looking at the furniture grade pvc that is colored and wanted to get peoples opinion. Furniture grade fittings are not National Sanitation Foundation (NSF) approved. This means they should not be used for plumbing applications involving drinking water. They are suitable for use in irrigation, sprinkler systems, aquaponics and other non-regulated, non-pressurized applications. So, does that mean its a no? Does anyone use this type of pipe and how's it working out? Any insight or advice is greatly appreciated. Thank you for reading and have a wonderful day
