I've been putting off this post for a long time because I thought I could find all of the information I need myself in order to build my custom 22 gallon sump, but there are too many variables and it seems that I have to start my own thread for my custom sump. I would like people to critique my design. All information will be appreciated and please feel fee to add/remove anything from my design. The questions that I have are indicated in red
Some prerequisite information:
First, let's start with the build of the sump tank itself:
- This is my first saltwater tank
- I have a 55 gallon
- This tank will be used for live rock, fish, and coral
- I will be building the sump tank INSIDE of my stand to maximize size (since the aquarium is already set up and I do not wish to take out the center brace to put the sump in
I will be building my own tank for the sump. I will be getting my glass cut into the specified measurements from my local hardware store and will be using 100% silicone to seal it. Sump Tank Statistics:
Glass Thickness: .25" For these dimensions, I will need the following cuts of glass:
2 Front/Back: 36" x 18"
2 Side: 8" x 18"
1 Bottom: 36" x 8.5
See attached image #1 for a visual representation. Now let's look at the sump design itself:
I researched designs, built a prototype, re-researched designs, built another prototype, washed rinsed and repeated.
I decided on a 3 section sump with the INTAKE on the left, REFUGIUM in the middle, and RETURN on the right. My design will need 4 .25" thick baffles. The baffles will be 15" X 7.75".
This is where my first question comes in: I decided to leave .125 or 1/8" on each side of the baffles for silicone. Is this too much? not enough? or just right?
I will have the following contents in each section:
INTAKE: Live rock rubble, protein skimmer (the protein skimmer will pump into the first baffle chamber into the bubble trap), 200 micron sock (15" length x 5" diameter) Is this too big?
REFUGIUM: macro algae, sand, and mineral mud
RETURN: return pump (information and questions below)
The baffles for the bubble trap will be 1" apart Is the 3 inch gap between the bottom of the sump tank to the middle baffle enough space? or too much space?
See image 2 for the sump design. Equipment time:
Here is a list of equipment that I will have: Plumbing:
I have not planned out the plumbing fully because I would like some of these questions answered first, but suggestions will be VERY appreciated (I will be drilling a siphon break hole into a u-tube on the display tank to avoid overflow in case of power outage.)
Thank you very much for reading this. I tried my best to do as much research on my own as I could, but still need help because I am a total n00b. Does anyone want to be my saltwater mentor? lol I am willing to trade software development/programming experience!
