Tunze6025.000 Nano Stream

I put this in a dead spot in my 75 gallon saltwater tank along with a wp25 and it fit the bill. It's only been in the tank a month so I can't comment on longevity. I switched to Tunze from Koralia because I have a box full of broken koralias!

It didn’t work after unboxing. It kept “rattling” in the water. I took it apart, cleaned it, and it didn’t help. I must have gotten a dud.

pure garbage

best pump company ever

My cichlid tank suffered a die off while I was away due to the malfunction of a cheap Chinese feeder. That and the constant replacement of Chinese powerheads led me to start over with only German made components. For my 55 gallon Lake Malawi Cichlid tank I use a Tunze Turbelle 6015 and a 6025 I have had for 8 months now for circulation. A German heater with a separate controller, an Eheim 2013 I have had for 30 years and an Eheim Professional II that is probably 20 years old. Don't skimp. Quality made costs more but the life of your pets are at stake.edit: The four Eheim units above have now been running silently for another year having survived multiple cleanings.

Since there are zero stars, I will give it a one.I've had about every good PH on the market. In fact I still have two Tunze PH's I've used for ~13 years with no issues.I ordered one of these to go with an MP10 for a drilled 45g drilled cube I built.Tunze no longer uses the good magnet...if you want the strength, you have to buy a 'magnet extension'. Looking at this picture...it's a misrepresentation as it appears the magnets are the same size when they are not...the box shows the same thing as well as this site: http://www.tunze.com/fileadmin/images/product_database/6025.000.jpgVery misleading.
