Question Which sump for a 180 gallon?

I'm planning a big tank project and I'm trying to figure out which sump would be suitable. Curious what others use and why?

I had a 60 gallon sump under my 220. You need a big enough sump to handle the overflow from the main tank in case of a power failure.

Are you planning on injecting CO2?

Here's the sump I'm running on my 210 right now. If you are going to run CO2, I'd stick with a design that keeps the drains under water, and also set up your overflow so that you are not sucking air. If you aren't going to run CO2, I don't see any problem running a wet dry configuration. They are quite cheap if you get one used from someone getting out of keeping reefs. The other question would be about what kind of fish you'll be keeping. If you are keeping shrimp or guppies, you can make a trip through the drain a bit safer for them.

Yes I'm planning on CO2 and shrimp and many small fish like neons. One of my many reasons for wanting a sump is ease of maintenance and minimum equipment in the tank. I have a tank with an Aqueon pro flex and I really like how its laid out it just seemed flimsy and began to bow out on the sides

The zeroedge sump that I showed a picture of above would be ok with a Herbie or Bean Animal overflow. The filter sock costs me endlers/guppies at about 1 per day. I have the megaflow overflows that I replumbed in a Herbie configuration. I have also ran a sump that basically was just a big refugium with a return pump behind a mattenfilter. Makes it more survivable for the fish that take the ride.

So I am going to use a Fiji Cube Low Profile External Overflow Box (Bean Animal Style) so I should be able to prevent shrimp, snails and fish from going down the overflow with medium PPI sponge, because I really like filter socks for ease of maintenance. I also want the sump to be as big as possible to increase the total system volume. I have herd of planted tank sump users sealing the sump to slow CO2 loss so perhaps one that is easy to seal would be nice. Many of the sumps that I have looked seem to be way more oriented toward marine reefs with probe holders and such. I am more asking others what manufactures make good quality sumps that don't necessarily have too many bells and whistles. Oh and thanks for everyone's input.

If you are looking for a simple sump just buy an acrylic aquarium, silicone in a couple partitions and buy an accessory filter bag holder that will attach.
I read the same thing about sealing the sump when I started but quickly realized its not possible due to cords and plumbing. Here is what I did instead and it works great; off gassing has not been an issue.






What you see is a 7" filter bag and a 7" pyrex lid, which fit together perfectly. And the end if my drain line which contains some plastic batting and a reducer fitting to help catch some bubbles. Also the standard 100 or 200 micron bags aren't fine enough, I started buying the 10 micron bags you can find on amazon. As a result my sump stays a lot cleaner, my tank is clearer, and I assume less co2 diffusion through the bag.

Another option: Google " wet sump swiss tropicals" for a diagram of a simple sump using Poret foam.

The wet sump was kind of what I was referring to, but I like to have a larger refugium area before the pump to act as a settling area for detritus.

So how dose the pyrex lid and the 90 degree fitting and the reducer and the batting help conserve CO2?

Have you seen the volume of bubbles in a sump if you don't use some type of filter material to minimize them? That's the off-gassing you're trying to prevent. Its more air- tight than trying to seal a sump, which is not practical. The reducer and batting just help trap more bubbles and slow the flow and reduce the noise from the rush of water draining into the sump.

Carbon dioxide is the densest of atmospheric gases, so you don't actually need to completely seal a sump to keep CO2 above the water. It's not like you are really going to be able to seal it to the point of pressurizing it anyway. Just think about the gas blanket that forms I've dry ice in a container (there is a temp difference there too, but it illustrates the point).

Unless the sump is a wet dry, you should probably be more worried about the overflow causing off-gassing.

Thank you for your help. I have a better idea of what I ma looking for now. I'm just trying to do as much research as possible to avoid a stupid purchase which is so easy to do in this hobby.
