AquaMaxx AF-RS170 Automatic Filter Roller

Designed for use with the Red Sea REEFER 170*, the Red Sea REEFER 170 Deluxe*, and similar sumps*, the AF-RS170 Automatic Filter Roller by AquaMaxx allows you to enjoy your aquarium with less maintenance by removing the need to constantly change your own filter socks or sponges.

Leaving clogged filter socks in your system for too long increases the chance for food and waste to decay and pollute your tank. The AF-RS170 eliminates this chance by automatically removing this waste from your water column before it has time to break down.

Water is fed top-side into the unit via your pipe drain or tubing-- no fittings required. As water passes through the chamber, the filter fleece begins to clog with detritus, uneaten food, and organic waste. The clog causes the water to rise within the AF-RS170 chamber and trigger the water level switch, which then signals the motor to wind the filter roll to a new, fresh piece. The water level will then drop and the process will repeat itself until the roll is near its end.

*Please note that the AF-RS170 will not work in conjunction with the stock ATO in Red Sea aquariums, as both products are installed in the same spot. When using the AF-RS170 in Red Sea aquarium models, it will be required to use a different method for auto top off of your aquarium. If you would like recommendations, please reach out to our customer service team.

No, I would not recommend this.

Needs improvement

Pros: Fits in the chamber

Cons: Roller paper is used quickly, roller paper is often out of stock, does not catch debris

It works, but can not be said to replace filter socks. I continued to run a filter sock even after installation of the Roller Filter and it is still become clogged every 3-4 days.

The float switch needs to be set higher. Turning off and on the return pump needless triggers the rolling motor wasting lost of expensive paper.

Not Ready for Consumers. Not a Filter Sock Replacement.

Pros: It fits in the chamber.

So like many Red Sea owners were excited to see a product designed specifically for the Reefer line. Unfortunately, this product is anything but that. After 2 weeks, here are my observations:

By far the biggest problem is that the float switch sensitivity. I use the reccomended 500 GPH pump on my set up. Everytime the return pump is shut off, and then turned back on, the roller goes crazy wasting a significant amount of paper. I feed twice a day with the return pump off. When the return pump comes back on, it needlessly wastes the roller. I adjusted the position of the float switch to highest possible position, but the problem persists.

The only way to fix this problem was to stack egg crate under the roller and elevate it out of the water. This makes the unit wobbly.

Not only does the thing burns turn filter rollers, but for some reason the pricing on 3.5 inch replacement rolls is 3-5 dollars more expensive than 4 inch roll replacements. You are looking at about $20 a roll a month if you can even get your hands on them. There are few retailers that sell them and they are often out of stock.

The next issue is the product, when working properly, leaves a lot to be desired. Be forewarned, this product is not a replacement for filter socks. After installing the roller unit, I kept the filter sock in place to see how much debris it would collect. Instead of changing the filter sock ever 3 days, I now need to change the filter sock ever 4-5 days. That's an improvement I guess, but it still means the roller filter is missing a massive amount of debris. For context, I feed 2 cubes of PE Mysis a day in a heavily stocked tank.

Lastly, and this is minor, but the designers should have used flat head screws on the installation of the body to make the unit easier to remove. I understand raised head screws make it easier to screw together on assembly, but the raised heads catch the bottom of the drain tube when trying to pull the unit out.

Overall, if you are willing to put in a few hours of monkeying with it, you can get it to work. But I'd recommend still running your socks, which makes this product far from exciting. That, mixed with increased prices of 3.5 inch roller filters; my final verdict is consider modifying other roller filters to fit the Red Sea 170 chamber.

Finally a Reefer 170 specific roller

Pros: Designed for Reefer 170

Cons: Doesn't have a controller so it can potentially go thru the roll if float gets stuck

I'm very happy that Aquamaxx decided to make an auto filter roller specifically for the Reefer 170. I was researching this type of product and all the other brands required significant sump modification for the 170. The best option prior to this product was a drop in filter that still needed modification to dam the filter cup area.

Installation of the unit was very straightforward and required no special tools. Installation into the tank involves shortening the two drain pipes by 1". A hand saw and miterbox made short work of those pipes.

I've only had it for a couple of hours so far, but already the results are noticeable! Way lower particulates floating in the display. I will not miss having to change filter floss every 3 days!
