IceCap Algae Turf Scrubbers use algae as a natural water filter to remove nitrate, phosphate, and other pollutants from your aquarium water. Rather than having algae grow uncontrolled inside your display tank, an algae scrubber allows you to grow algae in a controlled setting where it can be easily removed—thereby removing contaminants from your tank in the process. This all-natural form of water filtration can reduce and even eliminate the need for water changes. Best of all, algae scrubbers are safe for use in freshwater, saltwater, and reef aquarium systems.


IceCap Algae Scrubbers are designed to be mounted above your sump so that the water flowing through the unit can drain back into your normal filtration system. Water can be fed into the scrubber by a standalone pump, via a manifold, or through the drain of your display tank. The water going into the unit is trickled down onto a screen that is illuminated on both sides by powerful full-spectrum LED lights. As algae begins to grow on the screen, it “scrubs” your aquarium water of excess nutrients—so you’ll have less algae growing inside your tank. Once the screen is covered in algae, you “harvest” it by removing a sizable portion, thereby removing the contaminants that fueled its growth from your system.


Until now, hobbyists looking to setup an algae scrubber would either build one themselves or invest in one of the very expensive units currently available on the market. The problem with doing it yourself (DIY) is that not everyone is capable or willing and the materials may be unsafe in a wet and humid environment. Using a commercially available scrubber solves the safety issue, but the high costs of these units has historically been prohibitive for getting more hobbyists to adopt this effective form of natural water filtration.
Our goals in building the IceCap Algae Turf Scrubbers were to make them safe, easy-to-use, and most of all, affordable. You aren’t going to find a more affordable waterfall-style algae scrubber than an IceCap ATS!
Not only are units from other brands more expensive, some companies will try to upsell you another $60 for a “light shield” to prevent the bright lights from the scrubber from escaping and shining into your sump or living space. Not IceCap! Our scrubbers are already enclosed to stop light bleed. You don’t have to remove a bulky light shield to harvest your algae, either. Just flip open the hinged door on top to access the algae screen when it comes time for maintenance.


Open the door on top and loosen the quick-release union on the side. Lift the pipe and algae screen out and run them under water in the sink. You can use a soft bristle toothbrush to remove stubborn buildup. Be careful not to remove all of the algae from the screen as this will slow growth when you put it back into your system. Leave some algae behind to seed the next batch so that it will grow faster. Under normal circumstances, you will be harvesting algae every 1-3 weeks.


Many hobbyists prefer to run their algae scrubbers on a reverse daylight schedule to help stabilize the pH of your aquarium water. You can accomplish this by plugging the LED lights into a timer or aquarium controller and programming it for a 12-hour daily photoperiod that runs opposite of the daylight schedule of your display tank lighting.


IceCap Algae Turf Scrubbers are equipped with an emergency drain fitting in case the main drain ever gets clogged with algae.

No, I would not recommend this.

Cheap connections and poorly constructed

Pros: Lights are good; grew algae when it was running

Cons: Cheaply made fittings. Design of waterfall bar clogs easily and causes inadequate water flow

This unit worked well for about 3-4 weeks. I took it apart last Thursday night to clean the screen and put it back together. I noticed before that algae could clog the slots on the waterfall bar and cause water to spray in different directions. I didn't think much about it as it always appeared to angle downward and get drained out. Well evidently a loose chunk of algae from my sump made it through and clogged the pipe such that water sprayed up and out of the lid, dumping ~15 gallons of water onto my hardwood. I found it when I walked in at 5AM Friday morning to do my morning checkup.

This wouldn't be as much of a big deal, except after taking it a part to fully clean I can't get the drain ports to fully seal off on the acrylic side panel. I already wasn't happy with the construction of the waterfall pipe, but this has put me over the edge for a nearly $300 piece of equipment.

works great

Works great. Go to a local hardware store with the pvc end couplings so you get the right size. Easy to install. LIGHTS SCREW in at the bottom. Anybody can do it. Does not require zip ties like the other posted reported (that's bizzare). So simple to setup you don't need instructions. Almost any pump will work with it. I am using an old BRS media reactor water pump on high. Algae growth on this thing took 2 weeks to start, now it fills to the rim in 7 days. Buy the biggest size you can. I have the smallest because I have a 60 cube and wouldn't have the height clearance (opening lid is another 3 inches). Great buy!

We Be Scrubbin

Pros: Easy to set up

Cons: No instructions

My first impressions are very positive. The unit basically comes assembled except for the lights. Everything was well packaged. It didn't take very long to install, maybe a half-hour. It doesn't include a pump, so make sure you account for that. I am pleased with the appearance and performance so far. I like the colors. Makes me want to get more white and blue equipent for my sump!

IceCap 60w Algae Turf Scrubber - Medium review

Pros: well packaged. easy access to screen, saved time from building my own.

Cons: Not the same as shown. Very bright and hot. Disappointment in myself because I could have built my own for less than 100 dollars ad a few hours of time using same lights and materials.

Very bright, had to cover with black electrical tape to cut down on brightness. Came not as shown on advertisement had one LED on each opposite side with a box that looks smaller, like the box on smaller version advertised. Required zip ties to hold upper part of LED to box. Currently running one light because two get very hot.
