AWC Auto Water Changer (Plus ATO) - AutoAqua
Looks interesting and less expensive than other solutions. Anyone with experience?

I was looking at this yesterday too...was thinking about a simple ATO solution, wondering if this might be the way to go. I wonder what reservoir would be good to use, like a dosing tank?

I wanted to revive this and see if anyone had any experience with this water changer. I was looking into getting an ATO but if this can take of that and water changes then it seems like a good deal. Would this work on larger systems? I have a 210 gallon tank with a 100 gallon sump. I saw that the pumps were rates at 74 gph but I wasn't sure if that would be sufficient.

Wow that unit looks pretty slick, and ATO as well.
Hoping to hear some feedback as well.

I have seen this item for several weeks and have removed it from my cart several times, but I may just give it a try.

Very interesting. Will be checking into this more in-depth.

I’m so glad I saw this thread. I literally just ordered the AutoAqua micro ATO for my 8G invert QT 30 minutes ago, then I saw this thread, so I canceled that order and bought one of these instead. For only a little more I get ATO plus AWC for my nano tank. I imagine it will be here early next week and I’ll post my impressions as soon as I get it
Now I have a few days to decide if I want to try to run lines to my big NSW and RODI reservoirs in the garage or just use small reservoirs near the tank that I’ll need to manually fill periodically. |

My unit just arrived today and I just got it set up. So far I’m quite happy with it. The pumps are tiny and very quiet. I had no problem fitting the OSW drain pump and water level sensors into the tiny “sump” area of my 8 gallon AIO tank. The tube it comes with is 3/8 inch, which is probably overkill for my tiny tank, but it would definitely be good for larger tanks. I may get some reducers and switch to 1/4 inch tube which will be a little easier to run to the reservoirs and be less obvious where the tubes enter the tank.
Right now I just have the drain run across the counter to my sink and 5 gallon buckets on the floor next to the tank for my ATO and NSW reservoirs, but I’ll need to come up with a more permanent and less visible solution. It’s fairly flexible and you can use only the ATO or only the AWC function if you want. You can also initiate a manual water change at any time whether the AWC function is enabled or not. This device isn’t significantly more expensive than a stand alone ATO device and even if you don’t use the AWC function it would be a great ATO and give you the option to configure AWC in the future, or you could just set it up for ATO and use it to make manual water changes as easy as dropping the pump in the bucket and pushing a button. One note is that because of the way it works you probably wouldn’t want to use it for auto or manual water changes without using its ATO function. While you can configure it this way doing so might lead to salinity level creep over time. The issue is that for a water change you need to make sure that you remove and replace the exact same amount of water or it will affect the salinity level in your tank. This device uses two water sensors to determine how much water to remove and add. One high level sensor and one low level sensor. When it initiates a water change (either manually or automatically) it pumps water out of the tank until the water gets down to the low level sensor. Then it pumps new water in until the water level reaches the high level sensor. As long as the water is exactly at the high level sensor when the water change starts then this will ensure that an equal amount of water is removed and re-added. Since this device’s ATO system uses the same high level sensor to maintain the water level of the tank then you know that it will always be removing and re-adding the same amount of water. But if you are using a different ATO then it’s possible that the high level sensor might be slightly higher or lower than the normal water level in the tank and that would cause it to remove slightly more or slightly less water than it re-adds, which will slowly change your salinity level over time. Again, this isn’t a problem if you use the built in ATO function of this unit... it would only be an issue if you are trying to use a different ATO. As far as the AWC goes you can easily configure exactly how much water to remove and how frequently to run the water changes. As I said above, when the water change runs it simply pumps out water until the water level gets down to the low level water sensor. So by raising the sensor it will take out less water and by lowering it more water will be changed. You can set it up to take out exactly as much as you want. The auto water change works on a timer, rather than a schedule. You can configure it in 1 hour increments for any interval between 1 hour and 99 days. So you can adjust the water level sensor to only remove a small amount of water and do a water change every hour or you could move the sensor down and do a large water change every week or two. Or anything in between. Like I said above, I’m very happy with this device and it really does everything I had hoped it would. It makes maintaining my little 8 gallon nano quarantine tank so much easier. |

I've always wondered why these weren't a thing 10 years ago when I got into this hobby and saw how popular auto top offs were. Seemed like common sense to use a single unit to do both.
One more toy to add to the list of things I don't need and cant afford! |
