    Chaeto Reactors compared to Algae Scrubbers

    With more people wanting to use natural filtration for their tanks, we are going to look at the two main types of units that you can put on your system: Chaeto reactors (or "algae reactors") and algae turf scrubbers (ATS). We won’t be looking at refugiums however, since those have mostly a different purpose. This will be a multi-part post; the next post will start with the basics, so if you’d like anything in particular to be covered, let us know.

    Do algae scrubbers compete with macro algae growth rates? Growth rate comparison?
    What are the differences in nutrient removal between macro algae and green hair algae? Specifically regarding rates and/or types of nutrient uptake.
    Based on a single algae scrubber unit with no macro algae, is there a potential swing in parameter stability when one cleans their algae scrubber?
    -When the scrubber is cleaned there may be a delay in nutrient uptake?
    Further explanation in regards to reading the green hair algae color? Pictures?
    Does green hair algae help to scrub Co2 levels in the tank?
    Would it be advisable to run an undersized scrubber in conjunction with chaeto and other methods of nutrient export?

    Personally I run GFO, Carbon, and a Chaeta sandwich. I have never had very good growth with my chaeto likely due to my GFO and good parameters. None the less I have still battled green hair algae and cyano until recently. The problem actually came from an RODI issue. None the less I have looked into running an algae reactor seeing as it seems to grow much better then my chaeto.

    Not sure I understand this. Scrubbers are already macro aglae.

    Same question.

    Sounds like you are thinking that a chaeto reactor is the only thing that is macro algae. But, a scrubber is macro too.


    When the scrubber is cleaned there may be a delay in nutrient uptake?

    Good point.


    reading the green hair algae color? Pictures?

    Another good point. I know the colors and what they mean, but it might take some time to get it all together in one post.


    Does green hair algae help to scrub Co2 levels in the tank?

    Yes, that's what algae consume. More details coming up in Part 1.


    Would it be advisable to run an undersized scrubber in conjunction with chaeto and other methods of nutrient export?

    Interesting.


    Chaeta sandwich. I have never had very good growth with my chaeto likely due to my GFO and good parameters. None the less I have still battled green hair algae

    This hits on a major factor of reactors, which I'll cover.
