I was just wondering.. I have thought of a protein skimmer that could pretty easily be made from PVC
piping, but was wondering why manufacturers use acrylic? I could make a SUPER cheap one with PVC
and a Maxi-jet 1200 PH
. Basically it involves a pretty decently size PVC
pipe (size depends on tank). Use a Cap on the bottom end of the Pipe. Drill a hole on the side towards the bottom but at an angle so a "tornado" effect is made (where water will enter the system by the Maxi-jet). Drill a hole for the outlet semi-towards the top to dump towards the return pump of the sump/refugium. For the top of the Pipe (the main cylinder) add a smaller (not in diameter) cut pipe, but within that pipe silicone a mini funnel upside down, and voila a collection cup. The collection cup pipe should be a bit longer than the funnel (so the cup doesn't over flow with gunk). And heck if you wanted to have the collection cup housed, just cap it at the top. What do you guys think?
