So i have a 29 gallon tank that does not have a overflow in it. What i am wondering is if i can drill 2 holes in the back of the tank for the in and out to a sump. I have freshwater now and i know it works for that just wondering it i can do it for saltwater i really dont want to have a hangover system.

Thanx in advance guys

As long as the glass is not tempered you can drill and that is the preferred way to go.

There is a company that sells kits for these.

awsome... what size bulkheads would you recommend and how fare from the top would u think the drain should be???

Well it all depends. You actually do not even need an overflow kit. You can just simply put a bulkhead in the back and then a 90 degree elbow out of the bulkhead and you can control the water level with a piece of PVC with a strainer on the top. In that case you can put the hole where ever and use the pvc at the height you want.

If you want to go with a kit for an overflow then it will come with a template where you put it on the back of the tank at the top and just drill the holes with it..

those kits look real nice and pretty good on the price. i might start ordering somethings after mothers day got to go shopping for the wifes present then after that its game on for the build.
thanx all for the quick responses
