Due to popular demand I have taken some pics and built my scrubber in Sketch Up to share my experiences.

Due to current set up and space constraints I decided to go down the horizontal route for my scrubber.

One thing I wanted to avoid was a poor performing scrubber so I opted for a design which had two scrubbers with one effectively running on to the other.



This picture shows the inlet and the layout of the two screens and the lights. The lights are placed on a glass sheet which is about 2-4", allowing for the incline, above the screen.



Here is a different angle shot.



And this image shows the waterline. The second screen sits just below the water level which means the scrubbers is silent.

Its hard to take actual photos due to the covering on the tank but I have taken a cople of shots of the screen:





The large scrubber was cleaned on sunday and the small on yesterday.

You cant really see from the photo but the small screen which has reduced water flow over some of its surface is producing tough green algae and the larger one is producing the same and a darker algae.

I originally intended changing the second screen to ensure the flow was consistent across its surface but the different algae got my attention.

On saturday whrn I clean the larger screen I will get some shots for you all and I would welcome any comments you may have.
