I was gonna order a hog1 but I decided to make my own scrubber. Hope it does the job. I guess I'll see in a week or two if it's making alage. I basically took a Tupperware container top and sanded it down real rough then drilled holes in it. I strapped it to a piece of 3/4" Pvc which I also drilled holes in so the water will trickle down it. I had the jbj nano glo for my refuguim anyway so I hope its enough lite. My nitrates and phosphates are never high and my cheato grows like crazy so not sure how effective it will be. Let me know what you guys think any input would be awesome.
