Drilled holes aren't clean.

I like it. It's a straightforward, simple, and minimalistic overflow. It took about a month to break in and is now pretty quiet. The overall quality could be better, as some of the tabs that area used to tighten the bulkhead broke off, but this doesn't interfere with operation. As for controlling the water height, correct me if I'm wrong, but I believe that with most overflows you aren't able to control the water level. However, the water level is determined by the GPH of your return.

I appreciate your response, I should have stated it differently, the main thing I was concerned about was the water level would be too low due to how low the overflow sits from the rim

I searched for as many videos/pictures as I could before I bought the overflow because I was concerned about this as well. In my tank, the water sits about an inch below the rim and I can adjust it by adjusting the flow of my return.

I would take some fine sand paper and clean up the edges before I install the overflow gaskets. The glass may cut into the gaskets over time.

Agree with everyone, you got this!!!

+1 and wipe with denatured alcohol afterward.

I ended up buying an eshopps overflow because I couldn't find any definitive information on it

Nice! I've had an Eshopps overflow as well. Never had a problem with it.
