- AWC Auto Water Changer (Plus ATO) - AutoAqua
Auto Water Change Plus Auto Top Off
Change your reef tank's water automatically with AutoAqua's AWC system. AWC & ATO All-In-One. Water changes are one of the most time-consuming maintenance tasks with saltwater aquariums. There has been plenty of debate over how much water you should change and whether it should be weekly or bi-weekly, but no one argues against daily water changes. Changing 2% of your water every day will greatly increase your tanks stability and potential for longevity.
- Includes pumps & tubing
- Optical sensors = no moving parts
- Secure tube holders
- Siphon breaks
The simple system uses dual optical sensors, one for a high water level and another for a low water level. The high water level sensor acts as the ATO sensor, knowing when to refill your saltwater tank, from the freshwater reservoir. The top sensor also lets the AWC Touch controller know when to stop refilling the tank after a water change has occurred. The low water sensor acts as the minimum water level when a water change is in progress. During the water change, the output pump will pump water out of your tank our sump into a wastewater reservoir, or floor drain until the low water sensor is activated, telling the controller to turn on the input pump until the high water sensor is tripped, completing the water change and then reverting to a top off controller.
It is important to make sure the optical sensors are placed in the same chamber (usually the return chamber) where the water level will fluctuate during a water change.

Has worked great for two years By Mark on 1/9/2020Mark would recommend this product to a friendI have been running this system on my 30 AIO for around two years now and can attribute a lot of my success to this hardware. I have it dosing kalk in with my ATO and have it set to change some water out every twelve hours amounting to about 5 gallons a week. I have never had a problem with any of the pumps or the control system and I admittedly do less maintenance on the pumps than I should be. I would definitely recommend this system as it takes a lot of the chore out of weekly maintenance. Just keep the two reserve tanks topped off and you're good to go. I have my waste water drain directly to a sink in my basement.
Works great while it works. By paul on 12/18/2019paul wouldn't recommend this product to a friendHad a pump go bad after 2 weeks of use, now a month after that just had my second pump go bad. My sump is set up in my basement so thankfully the ATO beeps when a pump is not working correctly. Customer service with BRS and the manufacture so far have been good and hopefully that continues with the 2nd pump having died.
Great system By Kevin on 12/13/2019Kevin would recommend this product to a friendI purchased this system to top off and do a daily water replacement. Once I got it programmed the way I wanted it it worked great. A few days into using the system the DC pump failed. I replaced it with the AC pump and since then it’s worked really well. The Tunze system did the same thing so I think it has to do more with the little flimsy DC pumps they sell these systems with. All in all it’s been a great buy and solves my water change issues whereby keeping my tank healthy. That’s what we ultimately want.
Save your money By John on 11/16/2019John wouldn't recommend this product to a friendSave your money for a better one. My first controller fried on the first cycle. It was Happily replaced. My second controller hasn’t fried but is very untrustworthy often (every 2-3 days) needing reset. The pumps that come with it are rather weak. So after purchasing stronger pumps and the relays to run them it cost similar to the more expensive models that I wish I had saved to get
Needs work By Mark on 10/13/2019Mark wouldn't recommend this product to a friendWhile it works somewhat in manual mode, never turn your back on it. My setup is on a 220g w/apex and cor20 that ramps up.
Manual mode: first and second time pretty smoothly. Third time p3 didn't open up so I had to unplug and then plug back in.
Automatic mode: set my apex to power it up durning peak flow hours as I was told that it does have memory so I use the apex to power down during times the water level in the sump increases due to slower flow. Think I set it up to do changes every 2 hours of about 1.5g for the time it is powered. Just checked on it and I'm 2" above the top eye indicating it let 2x more water in than it took out! Very disappointed. The only way to run this thing with piece of mind is standing in front of it.
It is alright By James on 8/2/2019James would recommend this product to a friendFirst one had a bad pump. Second one was fine. The only real issue so far is that the ATO function turns off if you loose power. You have to turn it back on. You’ll need to put it on a battery backup if your power is flaky like summer in FL with all the thunderstorms.
Horrible By kurt on 7/3/2019kurt wouldn't recommend this product to a friendI put the little plastic caps in to the tubes to keep water from backing up into the system, it still backed up into my LCD screen and burnt it out. Don't buy this product there are better made ones without an issue like this.
Great design with many safety features. By Alex on 6/1/2019Alex would recommend this product to a friendAfter using this for over 3 months I can say this is a great product. You are able to do both water changes and auto top offs. For auto, top offs it will only run the pump for a certain time and if that time is surpassed than it will stop the pump and sound a very annoying alarm. For water changes, the pump surprised me and pump pushed water to my drain 25 feet away. But had to have a container of saltwater closer to the tank for filling the tank back up. Have had no problem so far and the directions are very easy to read! All in all, this is a product you need if you don't have an auto top off and/or going on vacation for a long time.
#1 reefer tool By Jonathon on 5/31/2019Jonathon would recommend this product to a friendEasy to set up, little pumps are strong, and quite accurate. Good bye buckets and siphons!
4 Faulty Units By Brandon on 4/17/2019Brandon wouldn't recommend this product to a friendI'm not one to leave a scathing review due to getting a faulty unit of any type of equipment – it happens. But 4 faulty units??
I had port 3 fail on the first unit. This is the port that powers the auto topoff. The brain would turn it on, but a volt meter showed that it wasn't being powered when the screen showed it coming on. After contacting Auto Aqua, then CoralVue, they sent me a replacement. The 2nd and third did the same exact thing. Port 3 failure. I just went along with the process because I liked the way it integrated in my system as an ATO and AWC all in one. And they were replacing them for free each time.
The 4th unit failed on port 3, but this time it failed ON. So the stupid thing pulled the entire volume of my topoff reservoir and dumped it into my tank. 20 gallons. Probably 12-15 gallons of overflow onto my floor.
Surprising, as I've searched all over and have seen nobody else mention this anywhere. CoralVue told me they were aware of an issue but unaware of a fix coming. Not sure how this isn't happening to a lot of other people since it happened to me 4 times.
Stupid of me to keep testing my luck. I won't buy another AutoAqua product. I really wanted this one to work.
works great so far after 2 months running. By brandon on 3/7/2019brandon would recommend this product to a friendThis has worked great for my system I have about a 400g system, I have it doing 5gal water changes every other day and I evaporate about 2 gal a day. Out of the box two of the pumps were stuck but a little tap on them to free them and they have worked ever since. The built in safety features are great as well. I mounted the pump high enough in my sump so it will never take to much water out. Highly recommend this product if you are looking to automate your system.
Worked well for a while By Al on 12/24/2018Al would recommend this product to a friendAfter installing it I had it doing manual water changes and auto top offs for about 3 months. Then during a water change it took way more (about 4x) of the water from my sump and the small pump to put in the new salt water stopped working. ATO is still working well but I'd like to know if there's a warranty. As long as it works, I love it.
Can this unit pump the fresh water in before pumping water out? otherwise the return pump chamber in my sump would run dry.
It will only take water in/out simultaneously. Doing them at the same time assures that the water level will stay the same.
Can you program this system to do daily water changes of xx amount at X time or do you have to manually start the water change with the push of a button
The AutoAqua AWC can do both scheduled water changes as well as an on demand water change at the push of a button.
Have a great day.
