Hi tetra10,

Schedule 40 PVC and Schedule 80 PVC (higher pressure) are inert.

Quote:
PVC pressure pipe and fittings systems are non-toxic, odorless, and tasteless. The National Sanitation Foundation lists them for use with drinking water.

It's definitely worth it to build the inline heater. It's customizable with the heater you want and it's cheap too (PVC isn't too expensive). The only thing to make sure to do is get aquarium safe silicone and let it cure before using it. I used GE Silicone I i think? It's the one without mold inhibitors. You don't want mold inhibitors.

yeah the GE silicone 2 has mold inhibitors so stay away from that. there are also aquarium safe silicones made specially for building aquariums and such. I would have bought that if I could find it (which I did after I bought the GE!)
