Glass dividers are best but you can use acrylic. ![]() Many people build their own sump with a 40 gallon breeder tank. You can purchase a ready-made sump or build your own. This is also done with just 2 baffles by simply omitting the third. Then, with the third, the water travels over again. A bubble trap is nothing more than 3 baffles. Sumps use baffles to divide it into separate chambers with bubble traps in-between. If you go with the flexible clear tubing, be sure to get the braided type to help eliminate kinking. Return lines down to your sump are typically PVC but can also be clear plastic tubing. It should be left above the water line so that it will be loud and help alert you to a problem. The only exception is the emergency return. When plumbing in a sump you’ll typically want to have your return lines end below the water level. Allows for larger equipment than hang-on-back (HOB) equipment.Adds water volume which helps stabilize fluctuations in tank parameters.Maintains a constant water level in the display tank.And due to it being above the water, it will make a noise. And exit the high T-piece back to the sump. If, for any reason the ball-valve did block again (and it did) The water will push up the UP pipe behind the tank. Now, how did it worked? By adjusting the ball-valve, you can adjust the water level in the overflow chamber. The out part went down again to the sump, but ended 2 or 3cm above the water. that part went up to another T piece with the horizontal part going out sideways. The horizontal part entered another 90 degrees pointing UP. The vertical part continued into a ball-valve, that entered another 90 degree, flowing down into sump first chamber. That was silent.īasically, I let the overflow go down to just below tank level, turn 90 degrees, and then a T-piece with the horizontal part of the T facing back to the wall. Thereafter I run a very interesting complex overflow. In general, is the width of the overflow enough for surface skimming and what is the optimum gap for the skinny overflow?Īlso still worried that stuff will get jammed into it, what is the best way to deal with this? My only really concern here is I have offset it enough to stay dry and if I should rather make the open channel a bit lower? The emergency channel is smaller and offset to the open channel, so it should remain dry in normal operating conditions and kick in and become a full syphon channel if the tank gets flooded due to any of the other two getting blocked or not being able to handle the flow. Big concern here is if I would be able to control the water level in the skinny overflow to this degree or if it will fill-up to the top of the overflow? I will configure the airline as a backup syphon activator as per the design. The open channel (that functions as durso) will functional as per the original design and because of the big difference in hight between the full syphon channel and the open channel, I will be able to control the water level with the valve on the full syphon channel so that very little water enters this pipe, resulting in a complete quite flow. This does not seam to be an issue with skinny overflows? Note this hole is already drilled, the line will also be fitted with a valve. A key concern here is that a vortex forms to the surface and/or the overflow box gets sucked dry. With the skinny overflow it is and will function as normal (on full syphon). In terms of the full syphoned channel, the traditional design requires it to be lower than the open channel. I could not find the need for this (theoretically) and think that I could use it inside a skinny overflow with some modification. However, it requires three holes (and three pipes) and the design is based on a classic box overflow and elbows to function. Of all the overflows I looked at the design ( Silent & Fail-Safe Aquarium Overflow System) is by far the best for me, both from capasity, auto adjusting, noise and its fail safe nature. To make life more interesting, I have bought a (new) second hand tank from and it already has holes drilled. ![]() ![]() I have been reading alot on overflows as I have ran out of "flood the house" credits and absolutely hate the sound of water gurgling or falling down a pipe and splashing.īut I love skinny overflows, both from an aesthetic point of view and space in the tank for fish. Think it is a bit boring for the normal tank thread readers and hope to get a bit more technical members in this part of the forum. Decided to start a separate thread for this and will only post the result of this back in my tank thread. ![]()
