An Auto Top Off container is perfect for holding a fixed amount of top off water. An appropriately sized ATO reservoir would be able to supply your tanks ATO needs for a few days if not weeks, while not being too large to cause a big salinity swing or flood the sump if the top off pump were to get stuck on.
Most auto top off units will come with a pump that will need to be in the reservoir to pump water to the aquarium. The Trigger ATO units come with a super wide opening to allow a pump to be placed in the reservoir while having small 0.25” holes for the tubing to be routed.

Matches my Ruby Emerald Sump. By Albert on 8/1/2017Albert would recommend this product to a friendThis thing looks sharp if you're ok with allowing aquarium equipment out of the stand. I originally was going to make a reservoir outside the stand and then cover it with something "furniture life". But after seeing how sharp this thing I decided to let my pride of understand technology extend into my living room. It matches my sump perfectly, doesnt look bad at all since its mostly clear, and most importantly its got accurate marks to measure top off evap and it has a large opening to refill so that water coming out of a 5g bucket doesn't spill everywhere.
So much easier By FreeSolo989 on 7/7/2016FreeSolo989 would recommend this product to a friendThis is a very well built product. Every thing is finished well and the product works great. I give it 4 stars because its not a true 10gal Reservoir. Its off by just a bit, its closer to nine gallons. But still in my application it works great and i would recommend to a friend
