Algae Scrubber Success.

Discussion in 'Equipment' started by Bruce Spiegelman, Dec 17, 2018.

  1. Just thought I'd share the pics of the growth in my algae scrubber. I've cleaned it all of two times. The first time was five weeks after it was set-up. This second cleaning was about a month since then. This thing is a beast! It takes less than five minutes to clean.

    Dang. That’s awesome. One day when I have more room in my sump.
  3. YOu don't need room in your sump. YOu need room above your sump. In my case, this one's on an Aquarium that doesn't even have a sump. :)

    do you have pics of how its set up? maybe algae scrubber would work better in my tank, i cant grow chaeto for some reason. just dies.
  5. My set-up won't help you a lot because it's on my IM 120 AIO. It literally just straddles the back section of the AOI. In most instances people put them on a shelf resting on top of their sump.
  6. And I couldn't grow Chaeto in this either which is why I tried this. Turns out they work great.

    Do you have any explanation on why the scrubber worked but growing chaeto didn’t?
  11. A couple of factors (I think.) First, scrubbers are optimized to be a perfect environment for the type of algae they grow. Second, hair algae may require different nutrients that Chaeto does. A lot of folks struggle to grow Chaeto even with good lights. So -- no. I don't have a real explanation other than it works.

    So some fun history...
    I used to really push algae scrubbers.

    In fact, I was one of the first to have real success with LED, way way back.

    But ... I have backed off a bit.
    The big problem - they work a bit TOO well.
    Your nitrates will plummet, and your corals will starve if you are not careful.

    So I had turned mine off and switched to Vinegar dosing.
    Although after my tank reboot, my tank was full of hair algae and nitrates,
    and I pulled it out of the box and cranked it up again.

    Now I am thinking of shutting it down again since tank is looking good.
    Or maybe making a half size screen.

    ALSO: You need to clean more often.
    That is WAY too much buildup. The dead parts slough off and really add to detritus.
    Clean weekly or at least every 2 weeks.

    Would it be good to run a few hours at a time? Or 24/7?

  14. Yeah. I realized a month was too long. I didn't expect that much buildup. Still learning on this thing. As to removing too many nitrates I saw indications of that from other's experience with them when I was researching, but often that seemed to be because they fell into the man-trap of reefkeeping -- bigger is better! I made sure this one is appropriately sized after discussing that issue with the manufacturer while at Macna (where I bought it.) It also does run through my Apex so if necessary I can scale back how many hours it's on if necessary. So far no need though as I feed this tank really heavy and since it's all LPS the nitrates are fine around 20-30. So far the scrubber has kept from nosing up to over the 50 mark though.
  15. Whatever your needs are. Mine (as of now) runs 24/7.

    Your phosphates staying within range as well? Is this your only means of export? No GFO or anything?

    Definitely check phosphates!
    While algae does have a decent percentage of phosphate, and thus exports some,
    it may not match what you feed.
    I use GFO.

    The pump MUST run 24/7. Algae will die.

    The lights should not though.
    Everyone is different.
    Max seems to be two 8 hour runs. (8+4+8+4)
    I generally ran mine for 10 hours at night, to try to balance PH.
  19. I also use two large bags of Chemipure elite below each return. I check phosphates once a month and if necessary will use a SMALL corrective dose of a phosphate remover. Although have only had to do so once since I switched to Chemipure elite and have been considering changing one of the bags to standard Chemipure Blue.

    I noticed the heart shape you made for us in the algae. Who says romance is dead?
