Did you buy a SCWD and hate it?

You have one of these set up Kurt??

Yup and it works great.

Is there any reason for concern with chemicals "leaking" out of the plastic or sealent?

Not if you use aquarium safe products. Your LFS should have them.

just dont put the sealant on joints that are immersed. If you looked at Melev's loop, he used regular PVC cement, just not in the joints that are in the water.
