I have spoken about my turf scrubber for a while now and thought it was time to expose those that don't understand this remarkable way to maintain a reef.

Dr Walter Addy in the book "Dynamic Aquaria-- Building Living Ecosystems" started it for me about 25 years ago. From high school thru college I had several freshwater fish stores that I supplied from a 200 tank breeding facility I setup. This gave me a pretty good background when I decided to personally get into saltwater in the early 80's. During that time it was kind of a killing field as few had the talent to keep coral, much less grow it.

I went thru the various stages, bio balls, canister filters, siphon overflows...the works. Then the Berlin method came along and I found I could ditch the bio balls for more live rock and the canister filter was replaced with a protein skimmer. All was well...except that when I fed my fish and coral, algae grew everywhere.

No amount of snails, algae eaters or other solutions seemed to work and I didn't want to keep my tank lights off or stop feeding just to try to stop the algae...besides even that didn't work. Then I read Dr. Addy's book and understood the idea of a dynamic aquarium.

Algae is the oceans friend...and it should be mine as well. It was a matter of harnessing it for good works rather than evil. In the Dynamic Aquarium, there are several things happening. For example, not using a fine filter so particulates circulate constantly. Tank water isn't Gin clear, but it helps keep some food stuff circulating for polyps.

The biggest concept was algae turf scrubbing (ATS) to me. In its simplest form it is a small sump with a dump bucket that spills water over a easy to clean grating material. That grating is being blasted by very close lights so the PAR is many times what is in the display tank. This is generally run while the display tank lights are out and is very effective with PH stabilization. It starves the nutrients from the water and concentrates them in the algae, which you can dispose of or re-feed to your herbivores. Very simple and very effective. No chemicals, no wild swings...very stable and that is what reef keeping is all about...stable.

In the following posts I will show my algae turf scrubbing system that has been running for almost 20 years now. It dumps 1.5 gallons every 10 seconds...that's 62 million dumps so far. If you can work with acrylic it is a straight forward DIY task to build one. But there are many different designs and many can be done at home.

Thanks for sharing your experience. Many of us would agree with ATS being one of the best ideas in the SW hobby. I'm adopting this for my FW tank as soon as I have the resources.

Terrance I'd be interested in learning more about how you adapted this concept for your FW set-up (or plans for it). Thanks

Hey Greg I have a question about a scrubber I'm planning. It's a 45 gallon tank and my plan for the scrubber is a CPR 300gph overflow and a mag 5 return pump and a 10 by 10 screen. I was curious if this sounds like a good setup .

Sounds good. If you can make the water surge over the algae growing area you will be better off as more algae will grow. The size of the growing area really only controls how often you have to harvest it.

Thanks. When you say try make it surge do you mean with ball valves to restrict flow and create turbulence in the screen feed pipe?

Turbulence will help, but I use a small dump bucket that creates a small wave. The growing surface is only just over a inch underwater, so the wave causes the algae to shift position which allows it to grow denser. That isn't a critical point but it raises the efficiency of the scrubber.

Its the exact same thing as people who do it for SW tanks. You can do it several different ways, so you just have to make it as simple or complicated as you wish. I did it the way that I like it: 2nd pump inside my sump to run water through a ATS.
