Crystal ATO reservoirs feature crystal clear acrylic to hold top off water for your aquarium in a closed container to help keep dust and debris out. The Trigger Systems ATO containers have a removable lid to prevent excess evaporation, while providing a large opening to refill the reservoir as needed.
Each ATO reservoir has two 0.25” OD holes for ato plumbing or wires for float switches.
Dimensions:
6” long x 14” wide x 15” tall - Overall reservoir size
3 7/8" long x 6 3/8" wide - Opening to refill reservoir size
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.

Great quality By Ty on 10/29/2017
Ty would recommend this product to a friendI went cheap on my first top off reservoir and paid the price. I was really inexpensive but slit a seam ran all out on the floor. This trigger system wasn't the cheapest out there but is awesome quality for sure. I have too much money invested in my tank to risk go cheap again. -
Perfect for Tight Spaces By Mical on 6/29/2017
Mical would recommend this product to a friendI purchased this for 65 gal reef and was perfect size for tight space I had near tank. It's well built and 5 star quality. Yes it's a little pricey for top up tank but it looks much better than a 5 gal bucket next to display tank. -

Great product By Strat1960s on 2/16/2017
Strat1960s would recommend this product to a friendI have a 50 gal cube tank and needed an ATO reservoir. I'm limited on space, so the Trigger Systems 5 gal crystal reservoir was the perfect option.
The reservoir sits on the floor between my tank stand and guitar amp. Risky??? I am completely confident the reservoir will not leak.
The lid keeps moisture inside the reservoir while preventing dust and dog and cat hair from falling inside and making its way into my sump and tank. -
Nice Product By Eagle1 on 5/7/2016
Eagle1 would recommend this product to a friendI have had this in operation for 3 weeks now, am I glad I purchased this product, clear, well built, I had to enlarge 1 hole for the tunze fill line but other than that no leaks, no issues, seems to be well built, -
