I recently started researching algae scrubbers coz I was having trouble with algae bloom despite 0 NO3 ans PO4, and was hoping to find ideas for an outsump, compact and clean algae scrubbers that wouldn't look an eyesore around my room and setup. Came across Santa Monica's scrubber which fit my bill perfectly, except that it cost more than SGD 1k including shipping costs! So I had a little discussion with my favorite DIY man, DE Lightings, and turns out he can fashion something very similar
