I'd keep it. That's what I use for 180G of water changes each week, and I love it. I did buy that metal adapter I posted after stripping the threads on the plastic one it comes with though. But until the plastic adapter gets stripped, you're all good. Just keep the metal one in mind when it comes time to replace that part. It's cheap enough, I'd recommend going ahead and grabbing it anyway, but that's entirely up to you.
