What is an ATO Anyway?

ATO Stands for Auto Top Off. All the Waterbox Marine, Frag, Reef, Pro and Peninsula Aquariums include a built in, or separate ATO chamber. This chamber is used to fill with Fresh Water. The Freshwater is used to replace evaporated Water within the Aquarium.

We recommend Purchasing a XPAqua ATO System to work with the Pre-Configured ATO reservoirs in our aquariums.

Why Choose the Ultimate ATO for your Waterbox Aquarium?

The Ultimate ATO includes 2 dual optical sensors. The 4 sensors allow the unit to be less intrusive to the Waterbox design while allowing a run-dry protection feature that prevents your sump from running dry. The Ultimate ATOs versatility is unmatched from any other ATO on the market which makes it a perfect match for our professionally designed Waterbox Marine, Frag, Reef, Pro and Peninsula Aquariums. It will keep your Water levels perfectly in sync with the integrated Waterbox ATO Reservoir that is built into all Platinum and Crystal Aquariums.

All the installation parts are included to make installing the Ultimate ATO a Breeze on your Waterbox Platinum or Crystal Aquarium.

ATO Didn't Last a Year

Bought this ATO back in May of last year. The male plug for the power supply built up a residue and had remove the residue. I typically unplug the power when filling up my reservoir for my ATO and plugged everything back in with no power to the unit. Don't waste your money for a cheap product that costs $169.99 when it's not reliable. I routinely maintain my equipment and everyone knows in this hobby equipment isn't cheap.
