## Questions & Answers

**Q: What size bulkhead does this use for the hole on the aquarium itself? It states the drain bulkhead sizes but not sizes for the aquarium itself.**
A: They provide hole saw to install overflow.

**Q: Is there anywhere i can find the mounting template for this overflow box? i’m trying to see if it’ll match the holes in a synergy reef shadow**
A: I have not seen a template online. The holes on bottom fit 3/4" bulk heads and pvc. I believe the whole on the back with the mounting bulkhead is 1 3/8". My partner and I drilled our own hole for mounting based on the size of the bulkhead and hole on the back. The product does come with a glass cutting drill bit for making the correct size hole.

**Q: What is the size of the hole saw?**
A: Not sure exactly size, I think its 2" however they do provide you with hole saw for the job.

**Q: Will the 2400gph model work on 3/4 inch thick tank walls?**
A: Yes it'll definitely fit

### ⭐⭐⭐⭐ Terrific, but almost wasn’t!!!
*by K***Y on December 15, 2024*

Everything is great! I love the low profile box inside the tank. The plumbing was just right for 1” PVC. The part that was a near miss for me: I use a bean animal to keep it quiet and it works like a charm. It’s virtually silent. But if the outer box was any smaller, and I mean any smaller, I wouldn’t be able to fit the 1” bean animal in it. I had regular PVC 90’s… and they wouldn’t fit! Scary!!! So I went back to the store and bought street L’s. They just BARELY fit… But they DO fit.
