View Full Version : Dual Sided Sump Design. 40 Gal Breeder for my 120

I recently purchased a 120 Gallon complete setup off craigslist that I upgraded to from my 55. The sump that came with it was only 20 gallons which is way to small for the tank and it had a crack where the bulkhead was drilled, so I decided to make my own. I've always wanted to do a refugium but never had the ability to add one to the 55 due to the lack of space. I decided to create a sump with a built in Refugium but when looking online discovered that they need a different flow than the rest of the sump. This got me thinking. I came up with a design to split the Sump into two compartments lengthwise, and split my overflow between the two so I can control the flow with some ball valves.

I started with the return chamber that would be shared between the two sides. I used acrylic for the baffles, I know, shame on me with a glass tank, but I left the required amount of space to account for water absorbing expansion. I used plastic shims for spacing and holding in place.

Then I added the bubble wall with one inch spacing.

Now was time for the exciting part. Dividing the sump! I ordered a piece of 24" x 24" black acrylic from amazon to prevent light bleeding into the rest of the sump from the Refugium. I measured the height I wanted the dividing wall, and 16 inches was perfect, so if for any reason it overflowed it would go into the other side and not out of the tank. I then cut the side baffle 1/2 inch shorter, so when it overflowed it would only go out that side into the bubble wall.

Next it was time to put in the last baffle for the Skimmer side. I decided to try to make a sliding wall similar to the Aqueon products which turned out pretty well other than one side cracking when trying to slot the acrylic. I'll redo it at a later date, but it doesn't affect the final outcome. I cut the acrylic into a U shape and then turned the piece I cut out 90 degrees and used it for the adjustable wall minimizing waste.

I also wanted to add some type of filter media, so filter socks seemed to be my best option. I created a mount for them to sit before the skimmer running parallel. I knew it would be quieter if I plumbed the water to the bottom of a chamber and then had it overflowing into the socks instead of directly into the socks. This eliminated the splashing noise and forcing the air bubbles from the overflow into the socks, with it also making it very easy to change the socks. This lessens the "nitrifying" effect of a wet dry filter, not forcing bubbles through the socks. I measured and cut the piece of acrylic and heated and bent it into a "Z" shape seen in the picture below. I used a Dremel and cut two holes at 3 3/4 inches in diameter to accommodate 4in filter socks.

Yes, I know I went a little heavy on the Silicon but the reason was the piece came loose while drying and started sliding down so I had to re-silicon over top what I already had, ugh.

I added a couple final touches, a water level jig to use my vertical float switches on with multiple locations and the entire bracket can be adjusted up and down or taken out for maintenance.

I know 4 float switches seem like overkill but I have my reasons. From top to bottom:
Too high (Fail Safe)
Ideal level
Water change stop level (For automated water changes)
Sump low (Fail Safe)

As well as a bracket I bent from acrylic to make a holder for my ATO and dosing lines.

All said and done it cost be $40 for the tank (Thanks Petco for your $1/ gallon sale) and about $60 in acrylic. Here is the final product.

With some water and Skimmer added:

Running on the tank, still need at add a ball valve to adjust the flow into the Fuge, Home depot was closed grrr.

And last but not least the final shot, Deep sand bed added, water cleared, Reactor plumbed (Not its final location). I will be adding some Cheato and filter socks tonight.

Final thoughts: I had a lot of fun building this Sump, its my first attempt but luckily I had no water leaks between compartments, the silicon work is a bit messy, especially since I only had the long weekend to complete the build and a lot of spaces you cant fit any masking tape because of the complexity of the build. I didn't divide the tank exactly in half because I felt the skimmer side only needed to be the minimum width for my skimmer which was 7 inches and left the rest for the Fuge. If you have any questions feel free to ask!

Happy Reefing!

I am also working on a small split sump with refugium and skimmer section split. I am planning on a sock filter for the skimmer inlet, but I don't see a reason for a sock filter before the fuge section. Any thoughts on this?

If you look at my design thats exactly how mine is done and so far its working great. Someone said to only put filtered water into the Refugium but that takes out nutrients the critters/algae need to live in my opinion. Honestly the water in your fuge should be the same quality thats in your DT as its the same water column.

Why didn't you just go to your local glass shop and get glass baffles cut? It really isn't that much. HD does this in most places. Those acrylic baffles are going to come loose at some point causing leaks between compartments. I've yet to see a acrylic on glass sump where this didn't happen.

You ever try to find black stained glass thats not an arm and a leg? I had acrylic in my old sump that was 10+ years old and it took me an hour with a razor blade to get most of it out. Perhaps they aren't using the correct silicon. I also prefer Acrylic for baffles because they are more durable, especially when having live rock setting up against it for long periods of time and taking pumps and skimmer in and out constantly. Also I dont have the equipment or know how to bend glass like I did for the Sock holders ;-).
