Better Than Expected!! Nov 26, 2020
Being a relatively new product, there were not many reviews available. However, it ticked all the right boxes, so I thought I’d give it a try. It has been a pleasant surprise at every step along the way. The drain section is in the center of the sump. This made plumbing much more compact. As always, advance planning is required to get the primary, secondary and emergency drains configured for best ease of use. From the drain section, water is directed in 3 different directions. One is to the refugium, where a gentle flow is generated. Another is to the LARGE skimmer section. A third is directed to a triple chamber media basket that can hold carbon or other media. I use carbon in all 3 chambers. The return section is large, and I use a Vectra M2 as my return. Included in the return chamber is a float valve for an ATO. I debated whether to use the float valve or a pump. Currently I’m using the float valve, and so far so good.

My two wishes is that if Eshopps is including a gravity-fed ATO, they should include a way to add a reservoir above the return chamber. Maybe some kind of “frame” that you could set a reservoir into. Also, they include a clear lid over the drain section. It would be nice of life’s could be configured for the other sections as well.

Also, when considering a light for the refugium, keep in mind that most lights cover an area larger than the fuge in this sump. I went with the ReefBreeders Pico. I’ll update with results.
