you can built them yourself,they can be use in both fw
aquariums,they go by a few different names(algae scrubbers,algae turf scrubbers,algae filters)their are a few youtube videos of diy algae scrubbers.people who used them, swear by them,saying that you dont need a skimmer when using one.i read about them on other forums and on algae scrubber.net. maybe is just new to me and most of you guys know about these. if you have used them before ,what are the pros and cons? of using them,and your experience,is it really worth building?
can you really go skimmerless?
