Yes, I would recommend this.

Great (small) sump

Pros: Easily handles all of your mechanical filtration. The fresh water reservoir is a huge bonus. Giving you access to extra fresh water for water changes or ato.

Cons: Skimmer compartment is super tight. The probe holders could be closer to the front.

I purchased this sump due to it having the extra fresh water reservoir. I did not see many (or any) other sumps with this option.
So far it’s been a little powerhouse and hold both my skimmer and algae reactor. It’s a tight fit.

Simple and sleek sump!

Pros: Thick solid acrylic with built in ATO container.

Cons: None.

Looks like a piece of art. Very solid design and build. Love the quality of the acrylic and the skimmer section is the perfect size. I also like that there is a built in ATO container.... definitely a HUGE plus.

Awesome sump!

Pros: Solid, clean, aesthetically pleasing build. Huge freshwater reservoir. Quiet. Easy to change filter socks. Probe holders and dosing tubes built in. Adjustable baffle.

Cons: No refugium. (Wasted space IMO)

I bought this sump because I do not need a refugium (don't think they're necessary unless they're big enough to have an impact) and it has a huge freshwater reservoir for Top off water which I needed because I did not want to have a separate unit for my top off and I'm sometimes gone for a week at a time for work. I'm super impressed with this sump. It really is a nice solid build. The lids are thick and durable. It has a nice sticker on front that shows your water level height. You can see into all the chambers from the front. It has 3 probe holders and 4 dosing tube connections built in. The entire sump has a rim/top if you can't tell from the pictures which I love. The adjustable baffle is thick and solid. Huge area for my skimmer and heater. It looks like I'll be able to fit a reactor in the skimmer area also. The filter socks are a breeze to take out. The lids really make this sump quiet. Really don't have any complaints. Took a chance as I haven't found many reviews on this sump anywhere but I'm honestly blown away. It just looks so nice and clean while having all the functionality you would ever need. Will be looking towards ice cap sumps for any future builds.
