I started this on UltimateReef so I thought I should share this with you here too. So, here are he details and pictures of my scrubber build...
DIY Algae Scrubber
So for this project I’ll be using…
780x210mm Sheet of 3mm Perspex
280x210mm Perforated plastic sheet (to be used as screen)
1 x Rigid pipe per metre (25mm)
1 x Hexagon adapter socket x female thread (25mm x 1/2")
1 x Hosetail (16mm x 1/2")
1 x End Cap (Glued) (25mm)
2 x Elbow 90 degree (25mm)
1 x Union Coupler (25mm)
1 x Ehiem Compact 1000 pump
1 x 16mm flexible hose
Note: I have not decided on the lighting options yet
From the spare piece of Perspex left over I have build the support housing for the “waterfall pipe”. I have constructed it from a single piece of Perspex which I marked up to the required measurements.
I used a heat gun to bend along the blue lines into the shape of a box and then glued along the red lines to join the two ends together.
Finally, to allow the pipe to rest on it I have cut a slot on both ends on the housing.
Here are a couple of pictures of what it looks like when it complete…
Connected the pipe pieces together to construct the waterfall pipe for the scrubber and cut a 4mm slot for the water outlet.
Initially I started to glue the plumbing together but after only gluing a couple of pieces decided to use PFTE tape and just push fit the remaining pipes. This is so that I can take it apart if I need to.
Then I marked out the slot on the pipe and used a Dremel with a grinding disc to cut it out.
Here are a couple of pictures of the plumbing and the slot for the water outlet…
And this picture shows how the plumbing will sit on the scrubber housing I built earlier.
The screen was very easy. Cut a notch at each corner at the top of the screen where it will fit into the slot and a small hole just below each notch for attaching to the pipe with a cable tie.
Here are some pictures to illustrate this…
