1200 gph overflow By Steve on 4/12/13
Steve would recommend this product to a friendWas originally going to get the 700 but learned after the Herbie method needs a bigger box for the fittings. I skipped the lid as I will probably be getting the net lid for tank. Looks good and will be siliconing with brs silicone. -
Great Product By Travis on 3/15/13
Travis would recommend this product to a friendI have a HOB overflow on my 125 and am always worried about losing the siphon, not to mention how big it is hanging on the back. I just got this for my new 75 gallon tank and love it. I will be putting everything from my 125 into this 75 gallon tank so I can add the same thing (1800PGH one) to my 125 and replace the horrible HOB one. -
Easy to install By Michael on 3/12/13
Michael would recommend this product to a friendGave this 4 out of 5 stars because there are no instructions with this overflow, it would be helpful if there was something to tell you how far down to hang this, and keep in mind that if you purchase the lid for this over flow you need to hang it down about 1/2 inch below the tank lid, and if you have an acrlyic tank that does not have a fully open top, you need to hang it down about an inch so you can get your fingers in there if anything would happen to fall into the overflow. With a little pre-preparation before you install this it will be just fine, overall, great product and will buy when I set up another tank. One last thing, make sure you use the right silcone when attaching GE Type I silicone works best...like I said a little instructions with this unit would make a novice feel more confident installing this product. -

well built By John on 10/10/12
John would recommend this product to a friendWell built, tight fit if you want to get two 1" sch 80 bulk heads inside it. I would recommend the next size if you want more than one in the sump. Can be done but it was tight. -

Great buy! By Reuben on 9/14/12
Reuben would recommend this product to a friendI bought this for my 40b reef tank and it is a perfect fit, not to big but big enough to allow for my 2 3/4 inch drains. -
Perfect in its simplicity! By Mike on 8/8/12
Mike would recommend this product to a friendOk I have had this overflow box installed and running for about three months now and feel its the best out there. I have been in the hobby for over 10 years and have pretty mech tried everything. The beauty about this overflow is in its simplicity. Easy to install and easy to use with a variety of plumbing designs. there is plenty of room inside for maintenance of plumbing fixtures and yet isnt huge and unsightly in the tank. The design of this box which requires bulkheads in the back wall of the tank is genius. SO easy to maintain and monitor not to mention how quiet it is. If you have a tank that is already drilled in the bottom, just cover the hole by siliconing a piece of acrylic over them and go for this setup. This is also great for tanks with tempered bottoms.

Hello would I be able to silicone this overflow box to an acrylic aquarium?
