Introducing our RENEW™ Automatic Water Change System
I wanted to take a little time to introduce the RENEW™ Automatic Water Change System and its operation. If you have any questions about the system, please feel free to contact us here through the forum or through our contact page.
The RENEW™ Automatic Water Change System consists of three major components: the Control Module and two Metering Reservoirs. Additionally, two small pumps are placed in the aquarium sump and the mixing bin to supply water to the Metering Reservoirs. Let’s first take a look at the Control Module.
The Control Module is the nerve center of the RENEW™. This is where the user tells the system how many gallons of water to exchange and how long to take to perform the change. The Control Module also provides information to the user, such as the number of gallons that have already been changed, the states of various water levels, and what stage of an exchange the RENEW™ is performing. The Control Module also alerts the user to any problems that the RENEW™ may have encountered during the water change sequence, such as a low water level in the mixing bin or sump.
As you can see in the pictures above, there are four buttons, a power switch, a numeric display, and several LED indicators on the face of the Control Module. Our goal was to make the user interface as intuitive as possible. The button on the left allows the user to set whether to perform the water change over the course of a day, a week, or as quickly as possible. The two buttons on the right simply adjust the number of gallons that the user would like to change. The center yellow button is the “GO!” button. It also is used to pause, cancel, or resume a water change. It’s actually the only button used for a water change. When initially depressed, it will start the water change. A second momentary press of the button will pause it, and a third momentary press will resume the water change. Pressing and holding the yellow button for three seconds will cancel the water change sequence, and pressing and holding for five seconds will cancel a sequence and order the system to empty the contents of the Metering Reservoirs. As you can see, it is straightforward and intuitive to interact with the RENEW™: simply set the number of gallons to change, set the duration, and press the yellow button. The RENEW™ then goes to work.
Taking a look at the bottom surface of the Control Module there are two AC outlets for the pumps. Also present, although hidden from view, are five receptacles for cables from the Metering Reservoirs, Level Sensors (optional or included with the Advanced and Pro models), and a communication cable that connects to the STORM™ Specialized Top Off and Replenishment Module if present. The STORM™ is outside the scope of this thread, but briefly, it is an automatic top off device that was designed to interact with the RENEW™ - it can discern whether water is being intentionally removed by the RENEW™ for a water change or whether it has evaporated. It will not attempt to top off with fresh water if the RENEW™ has removed the water from your sump.
The Metering Reservoirs are mounted to a solid surface above your sump and mixing bin. They receive the water from these sources and ensure that exact amounts are exchanged. Within the Metering Reservoirs, level sensors allow the Control Module to monitor the RENEW’s™ operation. There are two level sensors in each of the Pro model’s Metering Reservoirs, and one in each of the Basic and Advanced models’ reservoirs.
As mentioned above, there are three models of the RENEW™ Automatic Water Change System: the Basic, Advanced, and Pro. The Basic model comes with the Control Module, Metering Reservoirs, two flow control valves, and all necessary mounting hardware. Simply add two pumps and tubing and you can start enjoying the benefits of automatic water changes right away. The Advanced model adds two Level Sensors to protect your pumps and other equipment from running dry, plus two of our unique Level Sensor Mounting Assemblies that adjust to tank lips from ˝” to 2-1/4” wide and provide infinite sensor height adjustability within the tank or bin. Finally, the RENEW™ Pro includes additional Level Sensors within the Metering Reservoirs, increasing redundancy and expanding the Control Module’s capabilities. These additional sensors allow the Control Module to speed up the water change cycles and to make sure that the system is behaving exactly as intended.
There are many, many reasons for doing water frequent water changes. But why might you want the RENEW™ Automatic Water Change System? Here are just a few reasons:
1. Numerous small water changes eliminate large temperature, salinity, and pH fluctuations, among other parameter swings. Large “all-at-once” water changes can severely stress the inhabitants of your aquarium with parameter swings and the influx of raw trace elements and minerals!
2. Organic waste doesn’t have time to be metabolized in the aquarium, so less organic material goes through the nitrogen cycle and ends up as nitrate or other organic compounds in the aquarium.
3. Trace elements and minerals are added as they are depleted, so there is a more uniform concentration of the elements over time.
4. It isn’t necessary to turn off any of your other equipment – skimmers, reactors, filters, pumps, sterilizers – they all stay on, all the time.
5. Your corals and other critters aren’t exposed to air and possibly intense lighting, both of which can quickly damage the fragile tissues of many corals. Additionally, the toxins they exude to protect themselves are not produced.
Those are some of the benefits to your aquarium, now how about some of the benefits to you?
6. No more lifting heavy buckets. Your back will thank you.
7. No more dripping or spilling water all over the floor. Your spouse will thank you.
8. More time to do other important things! Whether it’s time spent enjoying your aquarium, cleaning skimmers, or time spent with your family – you’ll have more
time to do it.
9. You can enjoy the peace of mind that the RENEW’s™ redundancy provides.
10. Hey, it’s easy to do a water change now, so it’s more likely to get done! You’ll enjoy the benefits of a healthier, more stable aquarium.

Its about time someone invented one of these.

I love the controller and the whole concept. Very cool.
I am trying to get my mind around how you get around this type of setup affecting skimmers and the like. If the sump level goes down, doesn't that affect the skimmer? Does this pull water from the tank or the sump? How does the pro version work with the ATO so that there is not any SG flux?
Very interesting all the same.

I think it stated the pump goes into the sump, so it would draw the water from there. Also I do not think there would be an issue with water level, I would think it would take water out just as fast as it would replace it.

Thanks for the posts, everyone!
Great question, Matt. The RENEW™ can be installed to draw water from your aquarium itself or from the sump. Most people who have a sump install it to draw water from their sump. You are correct - the water level in the sump does drop in volume by 1 gallon, and then it is refilled. The whole cycle takes just a couple minutes from the time the water removal stage begins and when it is completely filled back up. The water level in your sump should never go above your standard running level.
If you have a partitioned sump, the export pump could be placed in a chamber after the skimmer so the water level in the skimmer chamber isn't affected. A common chamber would be the return pump chamber, provided there is at least one gallon of water volume above the pumps so they don't run dry when it is removed.
All versions of the RENEW™ (Basic, Advanced, and Pro) work with the STORM™ Automatic Top Off System so there isn't any fluctuation in specific gravity. Whenever the RENEW™ removes water from the sump or aquarium, it sends a signal to the STORM™ to let it know that the water was intentionally removed for a water change. The STORM™ then suspends top offs until the new water has been dispensed into the sump, bringing the sump level back up to where it was originally. The STORM™ then resumes its normal monitoring and tops off whenever necessary. Since the 1 gallon change cycle takes only a couple minutes, there is no noticeable evaporation in during the time the STORM™ suspends its top off functions. The STORM™ does top off between 1 gallon exchange cycles, so if you choose to perform the changes over the course of a day or a week, your water level and SG will still be maintained.
I hope this answers your questions, but if you still have questions please don't hesitate to ask!

I invented this over 3 years ago lol. And I didnt put into production because we are working on a system better than this concept right now.....Still makes me mad someone got a version of my first concept out before me.....darn it.

There are some concept flaws with this kind of water changer...I know from my first protoypes. Not very space efficient and also not to accurate. You have to keep ontop of your testing and I dont see that they point out auto syphoning issues and many other issues that may limit the use of this for many peoples aquariums.

Maybe they have addressed those? Good questions though. Don't be hating. I am sure yours will be great.
Do you sell bigger containers/Reservoirs for people with large tanks? Do you need to use those reservoirs?

Glad I was able to clarify it a bit for you. To answer your additional questions, we don't make larger Metering Reservoirs. The beauty of this system is that it can be used on just about any size aquarium. You simply adjust the number of gallons you would like to exchange, have your premixed replacement water ready, and press the start button. You can exchange up to 99 gallons with the single press of the button - over the period of a couple hours, a day, or a week. In contrast, you could perform just a 2 gallon water change over the course of a week if you wanted. This system is pretty much a one-size-fits-all solution, from nano tanks to display tanks holding several thousand gallons.
The Metering Reservoirs are indeed necessary, and in fact they're the ingredient that addresses both of Clam's concerns. The Metering Reservoirs are what makes this system so incredibly accurate as they "meter" out exactly one gallon per exchange cycle - of the water entering the aquarium as well as the water being removed from the aquarium. They also prevent any siphons from forming because they serve as air gap devices. Plus, since the RENEW™ systems monitor their own operation, if one of the Metering Reservoirs failed to fill completely it would interrupt its own operation and alert the user that there was a problem - and tell the user where to look for the problem through the indicators on the Control Module.
Thanks again for your questions - they help everyone understand a little better!
