Chaeto in refugium VS Algae Turf Scrubber?

[Scrubber_steve]

In my opinion an ATS can out compete cheeto big time. It takes up less space and can be built for less than $30. And I don't mean for a little 6" mesh one. Look for my DIY thread on how to build one shortly. I am creating the thread now. I just need to find my photos.

That price cannot include lighting

Red and blue LEDs are available for $25 on Amazon. A quick search finds several different ones available for $24.99 -26.99 like this one. https://www.amazon.com/UNIFUN-Growing-Hydroponic-Aquatic-Indoor/dp/B01F53LP46/ref=sr_1_19?s=lawn-garden&ie=UTF8&qid=1543040258&sr=1-19&keywords=grow+lights+for+indoor+plants
The ones I use are similar but with out the up LEDs.

Ok, but two lights are used for a typical downflow algae scrubber built these days. your method may be cheap but it won't be as effective as a properly designed & configured downflow.
