Hello everyone! Just wanted to come in here an ask for some advice. I just got myself a 40g breeder tank for my 30th birthday and was wondering what will be the best way to go about building it into a saltwater tank.
Should I drill it for an overflow box and sump? If so how large or a sump would I need to purchase/build?
If I were to go HOB or canister which will be easiest to set up and maintain?
I know I’m lookin for a unit that does about 300-400gph just don’t know where to really start. If anyone could possibly point me in the direction of an awesome 40g breeder build thread that would be FANTASTIC.

welcome and congrats, 40 breeder tanks are awesome! before you drill anything, you need to confirm it is not tempered glass, because if it is, it may shatter into confetti when you drill. Here is a guide on how to check for tempered glass:

Feel free to check out my tank thread for general DIY setup guidance with photos.

On the remainder of your inquiries, please read this guide, and then make a post if you have specific questions that we'll be happy to assist with: https://www.reef2reef.com/threads/the-supreme-guide-to-setting-up-a-saltwater-reef-aquarium.138750/

Check this out!

I would highly recommend drilling it for an overflow. A 20 gallon tank for the sump would be perfect! Looking forward to your build.

As far as what @TX_REEF said, he is correct on the tempered glass. However, most if not all, standard aquariums only have tempered glass on the bottom of the tanks.

In theory you're correct, but best practice is to double check before drilling. Manufacturers tend to use whatever glass they have available to them at the time, which can sometimes be tempered on the sides, front and/or back.

Happy birthday and congrats on the new tank!

You have lots of options here, and all will work. I'd suggest drilling it (if not tempered) and going with a sump. If you're looking to DIY a sump, I think the best value on a baffle kits is these guys here:

You can also buy or cut your own glass baffles, and certainly you can buy a ready made sump.

For an overflow, I think the best option right now are the ones from Modular Marine:

You could also consider a drop-in All-In-One (AIO) system like this one:

You could go with either a canister filter or a Hang On Back (HOB) filter (or both!), many here use those filters. Between the two, I personally prefer HOB's and specifically the Hagan/Fluval AquaClear filters. I don't care for canister filters because I find them a pain to clean, and I have had them leak on me. I like the AquaClear filters because they are solid workhorses with a lot of available add-ons like media baskets, and there's lots of hacks to make them more efficient for saltwater tanks. Here's an example:

You could also consider a HOB protein skimmer in addition to either a HOB filter or a canister filter. A protein skimmer helps remove dissolved organics before they can break down to cause excess nutrients that feeds ugly algae. Here's an example of a HOB skimmer, there are many others:

I'm sure you know you'll need a heater, and most here would suggest protecting your tank with a heater controller that can shut the heater off in case it fails in the "on" position, which is quite common, and can result in a cooked tank. The InkBird controllers are an affordable option:

And if you're planning on keeping corals, water flow is very important, you will likely need some additional circulation pumps besides your sump return/HOB/canister filter. Again, lots to choose from for all budgets, but these from EcoTech are very well liked here on R2R (so too is the cheaper Jebao knock off pumps):

All my links here are just examples, there's other options for all budgets, so don't think you *need* anything I've linked above.

I hope that helps and good luck!

Where did you get the AIO from ?
JaxsRacks makes one like in that post:

FijiCube makes another style:

I think you can find more on eBay and possibly Etsy too.

Good luck!
