  • Good product. By Monsterob on 10/23/2017

    Looks great. Ill buy another for sure. It fits 2 different sized hoses. You just push it on a lil farther, it gets wider.
  • Does not fit By Lola on 7/11/2016

    I bought the one for 1/2" or 3/4", it does not fit the 1/2" tubing I bought from BRS. It works fine with 3/4", but that's not what I bought it for.
  • Great build quality! By Joshua on 3/3/2016

    Very nice product, solid construction!
  • Does the job By dmolavi on 2/2/2016

    Does what you'd expect...gets the water back into your tank. A few modifications are needed to make full use of it though: 1. Drill one or two small (1/16") holes in the jet just below the water line to prevent siphoning if your return pump turns off, and 2. If you wrap the horizontal part in a small piece of foam pipe insulation, it will completely deaden any vibration. Great product.
  • Appears well made but does not fit appropriate size tubing By Butchy21 on 2/1/2016

    I purchased this to use as a return for my media reactor that I recently set up. I bought the 1/2inch to 3/4 inch size item to use with 1/2 inch tubing from my BRS media reactor and it does not fit at all, making it useless. The item appears to be made well but does not work as labeled.
  • Multiple uses! By MikeB on 10/8/2015

    These are great for a simple return. Works great. Looks great. Simple to install (use a hose clamp, obviously, as with any hose on a barb). Zero complications. Done and done.
    Additionally, I use one of these when I pump new saltwater into my tanks. I have an old return pump and hose I use to do this, but I have this return jet on the end. So, Brute can full of new saltwater, pump with hose and return jet attached, return jet easily hooks on rim of tank (I adjust nozzle so water shoots directly along the glass to avoid damage to corals or substrate), turn on pump (I use a power strip for an on/off switch) and then, instead of standing there holding the hose for several minutes, I can actually sit down and finish my b.... soda. Keep watch to avoid overfilling, and pull the jet out above the water before you turn it off (to avoid a reverse siphon), and roll the setup over to the next tank, rinse and repeat. This little device made water change day a lot more enjoyable.
  • Does the job By dave_pr on 9/27/2015

    If you're using a 1/2 tube put a clamp around it because it will leak. Another disadvantage is that the u tubes are too far away and will not stay in a single place once you put it in the tank. Besides that, works good.
  • Easy and inexpensive By Dave on 4/29/2015

    I tried this instead of plumbing my own return of a 40G breeder I set up as a frag tank. It was much easier and less expensive than doing it myself. I would definitely use this again and recommend it to anyone trying to soft plumb a smaller tank.
  • Works fine (but i'm still gonna drill) By John on 5/12/2014

    These are fine for over the lip returns, but I always seem to have fish which find access to the floor from the smallest of openings. Though a temporary solution for me, they are built durable and will satisfy anyone with over the edge plumbing and skimmer boxes.
  • These work fine. By John on 5/12/2014

    I wish they had some metric options to fit the 13mm included in some of the Eheim filters and pumps.
  • Gets the job done By Chris on 5/6/2014

    Pretty good alternative for anyone who doesn't want to drill their tank or is adding a HOB overflow to an established tank. I was able to contact customer service and they were able to tell me the exact measurements to determine how it would fit over the edge of my tank as well.
  • Awesome By Brennen on 4/2/2014

    This this looks way better in person than in the picture. Very flexable and easy to move. Installation was fast slid right into my 1" flexable tubing. Leak free with no tape or clamps. One thing you will want to do it drill a hole in it just above your water line. It will syphon tank water down to your sump if your pump turns off. Drill the hole start small and test it if, it doesnt work go bigger. Clean it if any algae grows on it the holes can clog in a few months pretty easily. Or drill a backup.

Product Questions

Are these compatible with 1/2" loc line?
Question by: Djplus1 on Mar 29, 2014 12:59:00 PM
Hi there,
While similar in concept they are not interchangeable. Loc-line is a brand name with its own standard that isn't interchangeable with other similar looking fittings.

Will these work 5/8" hose?
Question by: Jacob Martinez on Mar 18, 2016 10:12:00 PM
Great question!
This return jet in the 1/2" to 3/4" size will work with your 5/8" tubing. We recommend a zip tie or hose clamp to hold the tubing. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 21, 2016 10:56:00 AM
I curious about the dimensions of the 3/4" to 1" return jet. What is length of the drop to the ball joint on the outlet side and how big is the gap between the pipes? I want to use this for a return from my sump and want to make sure it'll fit where I plan to use it.
Question by: James Sykora on Dec 29, 2016 10:10:00 PM
Hey there,
The gap in the "U" of the return jet is just shy of 2 1/4", so anything under this should be fine. The ball joint starts at about 2.5", and the actual outlet starts at about 3.5" from the inside bend. Hope this helps!

Hi, I've got a tough question for you. You guys are good but if you know this one, I'll be really impressed. What's the maximum flow rate that can pass through one of these (large) returns? I've got a 1,000 gph pump but I think its being restricted. I'm going to get a 2nd one and split the return, but I'm curious what the max is..
Question by: Jim Kruppa on Jun 4, 2017 6:26:00 PM
Hi Jim,
This can be a bit of a complex question because this depends upon a number of factors including input pressue and acceptable pressure loss and velocity. Ultimately for most practical applications and regular hobby pump pressures, the most you are going to get through a 1/2" ID pipe such as the return jet would be about 400-500gph. For a 3/4" line you may get that up to a bit under 700gph. Bottom line, for those returns you are almost definitely being flow limited by the ID and losing flow capacity from your pump.

Hope this helps!

will 1⁄2" Mur-lok Polyethylene RO Tubing fit on this return?
Question by: Raul on Apr 9, 2014 7:31:00 AM
Hi Raul,
Unfortunately this would not connect directly to the return jet. You would need additional plumbing fittings in order to do that.
