My Sump Build

For many weeks i have been looking for a sump that would fit under my 29, but I could not find any with the right dimension.
So I decided to build my own.
The dimensions needed to be no wider than 11", about 14" long, and about 12" high. With these dimensions I didn't need to fabricate it from 3/8" Plexiglas, 1/4' would work just fine. I purchased my Plexiglas from Lowes, they carry .22" thick Plexiglas in their glass section.
I cut the pieces to rough size, about a quarter of an inch larger that my final size, and then trimmed the pieces to final size using what I call my ghetto router table. It is simply a piece of plywood that my router was attached too. A simple rip fence was just screwed to the plywood.

It is nothing fancy, but did the job very well.

The job of the router is to give you a nice smooth edge for gluing.
The next step was to glue the pieces together using the "pins method" that can be found here on RC. I used plastic speed squares to hold the panels at 90 degrees. The other thing that I used were two magnetic floats to hold the panels to the square.

I used Weldon #3 for all of the joints.
I let the joints cure for two days and then did a leak test.

Since I was building this sump for myself I also attached an extra holder for the pH probe, a place to keep the thermometer probe and the ground probe in place, and a extra holder for a piece of PVC pipe that I use to prevent a siphon from my ATO.
I'm surprised how easy it was actually to build this.
It fits very snug in the space that I had.

It also gave me about three more gallons of water, which doesn't sound like much, but in a 29 gallon tank that is about ten percent more.
Now what do I need to build?
 
Very nice Garry!!! :thumbsup: Can I convince you to make something simple at one of our meetings???
 
NIce job. That's the same way I built my sump, but I didn't have a router table so I had a plastics place cut the pieces. I didn't use the "pin" method, I just butted the pieces together and let the WeldOn wick in.

I think that the pins allow more of the Weldon to penetrate the joint.
I hadn't worked with Plexiglas in about 30 years. I normally use polypropylene and polyethylene at work on a regular basis. I think that the Plexiglas is easier to weld together. I'm thinking of seeing how well it will vacuum form. Most of the posts here on RC on vacuum forming are usually a little off center in the plastics world. Humm, I can see a cone skimmer in my future...
 
Jeff,
Total material cost was less than $50. If I was building anything larger I would have needed thicker Plexiglas which would have cost more.
For most sump projects you can use the extruded Plexiglas which is significantly cheaper than the cast type.

I looked a lot nicer when it was sitting there full of water. Them you put all that other stuff in it and cluttered it all up.:)

Guess that was your plan all along, huh. ;)

I am making my sump out of a 100g watering trough from Tractor Supply. :D Of course, I was not subject to space restrictions in my garage.

Wow, that's very reasonable. I'd like to second the request for a demo at a club meetnig if you're willing.

We having our basement finished out, and it includes a "fish room." Like Eddie, I'm probably going to use a 100 gal feed trough for the sump, but I'd also like to incorporate a separate fuge and a frag grow-out tank or two into the room. If I can learn how to make those myself, I could get exactly what I want and it wouldn't break the bank.

LMK if you'd be interested in a frags-for-training exchange!

I'm willing to demonstrate how to work with acrylics at a meeting, but I defiantly do not consider myself an expert. I basically have read what I could find here on RC, looked at some manufacturer websites that have been extremely helpful, and had the need to make my own sump.
I see it as knowing enough to make myself dangerous.
Working with the plastic is not difficult, like most things you just need to follow the basic guidelines that are fairly easy to find.

1. I didn't know you could buy sheet extruded. Your costs were 1/2 mine and my sump isn't that much bigger. That's good to know in the future but extruded isn't as strong (if you're going deep with you sump/aquarium/etc.

2. If you flame polish the edges, you'd have all the steps the professionals use in building consumer acrylic items.
 
Dave,
I really researched the differences between the extruded and cast acrylics before I purchased any plastic. The extruded was just fine for my shallow sump. The water level in it does not exceed eight inches with the return pump off.
I fully agree with you for anything deeper.
I didn't mention the final two steps of the build.
After I leak tested the sump I finished the edges with a flush trim router bit. That really made it nice, but the edges were sharp enough to draw blood if you scraped your hand on them, so then I took my propane torch and did flame polish the edges. That was the fun part.
The other thing that I discovered is that in the areas that there was solvent blemishes the torch also cleaned those up.
 
how do u like that marineland skimmer is that the 100. a buddy of mine has the 300. but he dose not keep his water level constant. hows it work if you keep the level the same
 
The Marineland skimmers are OK, So far I've tried a ASM Mini-g, but it would never quiet down to an acceptable level for my tastes, so I pulled it and put the Marineland back into the sump.
Next I'm going to try a Tunze Nano DOC 9002. They are reported to be super quiet.
I also have another Marineland skimmer that I have been playing with. I cut down the inner neck and added a bubble plate and the next step is to add a riser pipe to control the water level in the body. We will see how well it works when I get it finished. I'm also going to try some different pumps in it to find one that is really quiet.
Are we feeling a theme here? Really quiet....
