  • Significantly decrease the risk of algae outbreaks.
  • Keep waste and particles suspended longer so skimmers and filters have a better chance of removing them.

  • Good flow, but loud pump By Damian on 1/7/2017

    The pump is well constructed, the magnet is solid, and the flow is very adequate for this size pump. However, I found the pump to be somewhat louder than I expected. It gives off a noticeable deep/low humming noise when running. I'm not sure if this is how loud it's supposed to be as I have no way to compare it to another pump, but Tunze has been contacted to see if there is anything I can try to quiet the pump. I will update this review when the issue is resolved.
  • OK Pump By James_H on 3/19/2016

    Recently purchasing 2 small pumps for a nano, the tunze 6020 was one of my choices. Having 3 pumps in a 10 gallon tank required careful consideration of the power consumption (I don't have a chiller). Using only 4 watts is this pumps primary selling point. The flow pattern is dispersed and as others have stated is not deflected quite enough. The pump does put out more noise than I expected as well (even with the rubber isolation feet supplied it is louder than my skimmer).

    One thing to note is that upon startup, the impeller may begin turning the wrong direction (yup its AC with a true impeller... not a like a centrifugal pump), and the pump was designed to correct the rotation with small bumpers that stop the impeller and bounce it back in the counter direction. This process creates a noticeable chattering sound when it occurs at startup.... would definitely not recommend this pump to be used with any sort of wave maker.
  • Great little pump !!! By jhmeresqu on 2/7/2016

    Nice, compact, low power consumption.....used in sump for circulation of detritus......great little mag-mount.
  • Fair quality so/so performance By Bruce on 1/23/2016

    Runs reliable, replaced a Hydor Koralia Evolution 600GPH and doesn't seem to have as good of performance so will only be effective in a very small tank or for a small spot flow. Have it in a 20 and it is only good for a corner area of the tank. Little rotating deflector only about half deflects flow so a flow perpendicular to the mounting surface is not possible, will only divert flow by about 45 degrees. Mounting system works good and pump is quiet, I hear this pump make no noise as others have stated. Have not had this pump fail to run either. It does pull so little power I had to run it on Apex EB8 outlets that are relay controlled, the solid state outlets 1-3 & 5-7 will not turn off with only this on an outlet. Price is good for the quality.
  • Flow is neet By Andre on 10/10/2015

    creates a very unique gyre type flow pattern in the tank, very similar to the one i saw on you tube today.
  • Disappointed By NavyCove on 4/12/2015

    1. Bright blue colored ring makes this hard to camouflage. It stands out in the tank.
    2. Nice flow. Corals liked it immediately in my 30 gallon.
    3. Way too loud!. I'm moving it to quarantine tank which is in a room whereI don't have to listen to it.
  • Small and powerful By aaron on 2/17/2015

    This pump works great. I have had for 4 months now in a 4gal. Sps tank. It has powerful Broad flow. I have it aimed down towards the bottom of the aquarium. It Keeps all the detrius off the bare bottom. The Only thing is the pump is louder than I thought it would be but not a big deal
  • Decent Pump By Matt on 12/21/2014

    This pump isn't designed to be used like a regular powerless and if you use it correctly it's great. I find the flow deflector to be very useful to spread the pattern out wide. I have mine pointed straight down on the back wall, with the deflector aimed between two large rock formations. It really keeps detritus up off the rocks and sand. Buzzes a little on startup and I find the cord to be a little short.
  • Not up to usual high standards By reefergl on 11/14/2014

    In the short time I have had this, not even two months, it has stopped working twice. I then take it apart and put in back together and it works again.

    For me this is not up to the usual high standards of the Tunze name brand.
