Comments: Great product. Fast shipping. Ran for a couple hours in a vinegar bath to get the mfg oils off of it, dropped it in the sump. Started pulling right away. Tunze makes great aquarium products.

Comments: Had a 9015 years ago and fell apart was $$$. This one is made so much better and one thing is you can see redux/orp come up immediately upon turning on so efficient. The short reactor is to avoid waste coming off the bubbles which tunze observed with tall skimmer designs many years ago. That is why theirs are short. A+++

Comments: I've been using the Tunze 9410 for about a month now and it's a real work horse! The skimmer is compact with a little flimsy top but all and all it works as reported. It pulls black tar looking substances from the unit into the skimmer's cup. Easy to set, never overflows. I would have given 5 stars if the owners manual was well written. But it's easy to assemble by just looking at the photo. Yes I would buy again....hopefully this will last a lifetime!

Comments: The skimmer is only a few days running and still breaking in. It still outperformed my previous skimmer that was rated nearly the same. Only complaint is a small sump space and the footprint was closer to 6.5" by 10" and was barely too big for the compartment that I had planned on putting it in. I would still have purchased this knowing I would need to re-arrange my sump.

Comments: In the two weeks I've had it, this skimmer is pulling some really dark product. It foams consistently and level is very easy to control. Everything I have come to expect from Tunze.

Comments: The only adjustment necessary may be a little on the air. Once set in this skimmer can produce with the likes of Bubble King and the better Octopus models. Excellent quality skimmer and easy on the wallet (a match that's hard to beat).

Comments: I am still breaking this in, but so far it has skimmed more from my 90gal than the EV-120 it replaced ever did. I was never able to tune the EV-120 to get the skimmate in the cup. This one has no adjustments needed. Dropped in the tank and every day has had dry foam in it. Cant wait to see it in normal performance. My only issue is that, so far, the collection cup is vibrating noisily and I have to adjust it to stop it. May need to go back to the manual to see what I did wrong... If possible, I will update once I have this in a while.

Comments: I hooked up this skimmer to my 175 and it started to produce foam immediately. This one is definitely better built than Tunze's older line of skimmers which fall apart. Its been put to work for the last 2 weeks, very very quiet and works great.

Best skimmer I have ever used

Comments: After much research and analysis I settled on the Tunze 9410 to replace my Reef Octopus XP2000 cone skimmer. I needed a skimmer that was smaller in size than the XP2000 and at first I couldn't believe that the Tunze 9410 at about 16 inches tall was capable of the kind of performance that I read about on the web. Well, it is, and in fact exceeds the XP2000 which I had regarded as a pretty good skimmer. In my mind the Tunze pump is clearly better than the Bubble Blaster that powers the XP2000. And as for the "cone thing," been there done that.

Comments: I have been running this skimmer on my 90 for almost two years and love it! Pulls out about a cup of seriously dark goo every week or so. Highly recommended.
