Best Automatic Water Change System?

Hi

Iíve a 180 gallon system. Lightly populated with fish

If I was to do a daily AWC, or weekly, what would you recommend in terms of amount per week or two weeks?
(My nitrate and phosphate are almost undetectable)

And what system is the best in terms of quality equipment? The Neptune DOS seems a bit plastic!! And amazon reviews donít seem great or mixed at best

Check out the Genesis Renew. Iíve been using one for years and there is nothing quicker, more accurate and easy to use. While itís not cheap, nothing beats the Renew when it comes to AWC. You can change out 1-99 gallons a day, week or continuous and it will change out a gallon every 2-3 minutes and never needs calibration or tubing changes.

Looks great! Not many people really talking about it say compared to a Neptune. Surprised it doesn’t get more coverage

So what’s the advantages of this over the Neptune for example? Considering that the Neptune can adapt into so many other functions?
Not knocking the Genesis at all, it looks awesome

1 gallon every 2-3 minutes.. No calibration. No tubing to replace. No converting ml to gallons. No programming. If you need to do a large water change, you just push the button to tell it how many gallons to change and hit start. Try doing a large water change with a peristaltic pump and then compare that to a device like the Renew. There is no comparison.

As for why it doesnít get more coverage, itís mentioned plenty in threads like this. But also consider itís close to double the cost of a peristaltic pump and has more complex plumbing requirements. Or maybe itís just the best kept secret!

Here is part 1 of a 4 part video episode I did on the Renew when installing one on a friends system. You can get to the other parts by clicking the video and viewing it on youtube. Part 1 covers unboxing and an overview of the system. The other parts cover the installation and finally using it.

This is excellent thanks for breaking it down like that

I do need a robust easy to use system that can do large water changes. I have a 180 gallon system, or 150 display. How many gallons would you suggest changing per month or week or day?

I’ll be totally honest. Life’s been crazy I didn’t do a water change in maybe 8 months or more and when I tested nitrate and phosphate I was expecting it through the roof and both were almost undetectable, the system is well established at least, up and running a few years

So this probably requires an RODI resovoir, Saltwater made resovoir, and a third resovoir for mixing saltwater

It doesn't require an RODI reservoir unless you implement some sort of ATO which I would highly recommend. I don't use their Storm ATO solution. I use my Apex and that was also used in the customers install. Their optional Storm ATO makes ATO plug and play and it interfaces directly through the Renew though it does add additional expense. As for the 3rd reservoir, that would only be needed if you don't have a place down stream to route the waste water. Keep in mind that everything needs to siphon from the metering bins which is explained in detail throughout the videos. If you haven't watched all parts of the videos, I would suggest doing so. That way you know exactly what is entailed in the install.

So what would be the reason to go Neptune or Genesis? It seems the Genesis like you say can move larger volumes, which is good for my 180 gallon system.

So why is all the hype about Neptune? Is there still a place to mix and match and do both or is it one or the other like Mac or PC?

What would be the place or function of Neptune if I go the Genesis way?

The Neptune DOS is a doser first. Consider that the majority of people have smaller tanks and smaller budgets. DOS is considerably less and appeals to people with smaller tanks and lower budgets when ti comes to AWC. Thatís not to say that people who have large systems donít use the Dos for water changes because some do. I have a Dos but I have a larger tank and for me, being able to do a large water change quickly at the push of a button as well as daily water changes was a consideration. The Dos is a solution that you program to do a set amount and it does it slowly. Try doing 50 gallons with a Dos. I used a Litermeter III before switching to the Renew for this very reason. The Dos is a great solution but for large volume water changes on a larger system where one would want the flexibility of fast water changes when needed coupled with the ability to do automatic daily water changes, itís not ideal. If you only want a solution to do smaller automatic water changes and plan to do large water changes automatically, then it may be great for you.

Autoaqua awc is easy to use and reasonably priced, and it does water changes and top off BAM!!!

The downside to level switch based AWC’s like the AutoAqua is that is does water changes based on a level sensors and in this case an optical level sensor. Water is pulled out for a set interval and then refilled until the sensor is tripped. Level sensors will always very from one trigger to the next and the result is salinity drift over time. The greater the variance the faster the drift. The larger the sump, the less accurate they are and optical sensors are even more prone to variances than mechanical float switches so you need to monitor your sanity with level sensor based AWC’s. That’s one HUGE advantage of the Renew. The metering bins never vary as long as they are level and you will never have salinity drift. That’s not to say that devices like the AutoAqua aren’t worth considering but they have their short comings and limitations so that is just something to consider. But if cost were the driving factor, then that is certainly a good option. For me, the Renew was the best option due to ease of use, speed and accuracy. I could have accomplished the same thing using a couple pumps and my existing levels sensors with my Apex but the Renew offered a fool proof solution that was fast, accurate, gallon based and spot on accurate in and out without ever having to worry about salinity drift or changing programming in an emergency or when I wanted to do a larger continuous water change rather than my regular 5 gallons a day water change. Since I use my controller for my ATO, that wasn’t something I needed to worry about with my AWC so accuracy, speed and ease of use were my biggest concerns.

Build quality is a big concern for me
Everything seems made in China today and plastic I would definitely prefer higher quality pumps, hardware, etc

Can I just ask, if I buy this with the storm ATO also, are the two systems married or still different?
ie will the drop in water level during the water change trigger the ATO ? Or do they run from the same controller such that the system understands ‘hey I’m not low level in the sump I’m just doing a water change?’

Because if not then why bother with the Genesis Reef Storm?

I shot an email off to them last night and waiting to hear back. If I go that direction I would likely buy both

Do they do Black Friday? Lol could be waiting if they do good deals

The Storm is married to the renew when the two are connected to each other. The Storm knows when the Renew is doing a water change & automatically pauses during water changes & will only activate after the water change is complete.
