Tang only tank 8 too many for my 135?

an internal overflow is really easy to make ,,, its a good acrylic project..for less than half the price,, i built my own

i sealed mine once and it has worked fine for me... the only measurment you want to get just right is the height of the overflow and the depth of the teeth. decide how high you want your water level and cut your teeth about 1/2" below that. they are generally a 1/4" wide and an inch to inch and a half deep.

I know that most tanks use an overflow but I do not think they are necessary. I simply have a pipe with a screen at the top the acts as my overflow. I get the surface skiming without using all of the space that an overflow requires. The slotted screen at the top prevents any fish from entering and acts as a muffler so that the noise is minimal.

You can also use eggcrate for the top of the overflow. This will allow more water flow and less trouble to make (silicone it on top of the overflow box)
Depents on the flow rate of the return pump and lenth of the overflow area, you can expect the water lever to be aobut 1/4 to 1/3 inches above the acrylic height.

I have not heard an aquarium using the durso standpipe so I can't compare. AllI know is that mine is pretty quiet. You can come by and check it out if you want.

The eggcrate idea is great as long as you have no small fish or those darn cukes we got from the last order. When I eggcrated my small gobies and a few other small guys (the gobies were my favs so I remember them) could easily go through the eggcrate and proved it multiple times.
I love those cukes from the last order. They do nothing for my sand but they are always on my glass (top by water line) or squeezing into my overflows. These are the first cukes that I have ever really been able to watch a lot. They are never in the sand! Anyone elses do this?

hey mike,

i've was kind of interested in making me a overflow box also so when you made your overflow box how did you go about cutting all the slits without breaking some of them. did you use heatstrips to form the the 90 deg. box or just glued two pieces together? one last question what thickness of acrylic did you go with. thanks for the info.

That's hilarious! Mine don't like the sand much at all. I have a finer sand bed in my other thank and might put one in there to see if they like it. I am guessing that they do not like my substrate! But they are great to watch! They just cruise my glass and leave strips of clean (well, slime free) glass!

Cucumbers need fine sand. You are exactly right when you say they don't like your substrate, if you have crushed coral. It can also kill them if they try to process the sharp coral pieces. Finer sand is usually best for cucumbers.

Ray, i used 1/4" black acrylic. i just glued two pieces together. you can use a table saw to cut the slits... i have a saw if yoiu need help with that... very simple and like i said i have had zero problems

[Tim Marvin]

Overflow boxes seldom leak or at least pose a problem. they have constant pressure against them from the tank.

There are fish stores in Austin that can drill your tank, as well as make/install the overflow for you.
