Herbie-Style Overflow System with Hose-Barb-Bulkhead Fitting?

[SkyReef]

My new, 80-gallon setup is using a Herbie style overflow. It has a 3/4-inch main drain line and a 1-inch emergency drain line. The drain holes were pre-drilled at the bottom of the tank, inside the corner-overflow section, by the manufacturer Deep Blue.

I've used slip bulkhead fittings before, where the PVC is slipped into the bulkhead stem and glued in. No problem. Never failed. But my new setup came with a different type of bulkhead fitting, a hose-barb-bulkhead fitting. Will this be okay for such a critical flow path that will carry a siphon flow of water? It just seems that a hose-barb fitting is not as durable, leakproof, and failproof as a hard-glued PVC fitting. But maybe I'm dead wrong. Maybe the hose-barb bulkhead will be just fine. Your thoughts and experiences are most appreciated.

Here are some pictures of the fittings:

I just picked up a used tank with those bulkheads, I got new ones, those deep blue ones seem very cheap, threads were crap and seals were flimsy. New good ones aren't very expensive for such an important part.

I've used the hose barb bulkheads before with success. They are quite durable. The 'issue' is that the hose barb restricts flow somewhat more than a regular bulkhead. Only a problem if you are on the edge of having enough flow.

I would toss those and get some proper bulkheads. They aren't that expensive. Those barb fittings look like the ones used with the clear flexible tubing, not PVC. That stuff leaks if not clamped very well, and also grows algae from the light getting in. Plumbing will be much easier with standard PVC.
