Hello!
I have just started building my scrubber today and the plastic canvas is coming tomorrow. I'm trying to work out how many layers of canvas i should use. I will be running a lamp on either side probably a 24w CFL 2700k My tank+sump is around 550L with my sump has the return going into the refugium fire then into the skimmer compartment then to return pump compartment. So I have planned a 9" wide screen and 11" tall (1" in the water). I have two pumps both 1200l/h the one in the pictures has a filter and valve built in to change the flow amount. I'm thinking i should have 3 layers of canvas that way it will always keep a nice bit of algae in the center to seed the out sides when cleaned. Is it worth doing or just stick with one sheet? I was also thinking this would let me clean each side at different times so there is always a good amount growing.
The water level is just under the bottom of the unions.
Doh the uploader changed the pics to landscape!
