Great Skimmer

Comments: 65g fish mixed reef and 10+ gallon sump. Wanted a skimmer with a rating much much larger than my current or future intentions even with 38 gallon refugium coming soon. I wanted to wait a bit before rating this skimmer so I had a chance to see what it was made of. I ran the skimmer in vineger for a few hours to get all the factory garbage off, oils, excess junk, etc... Put it in, got it adjusted (air flow) and it started swimming shortly after. It is a wet skimmer, which is fine even tho I prefer dry, it still skims great!! Water level must be kept constant or it will fill collection cup too quick. It takes a few days to get the air flow right for it to break in. Pros: Great skimmer, quiet, little expelled microbubbles, post filter can be used for media, overflow protection works great! Cons: None come to mind, other than when the water is pushed into post filter in has a very slight slaping noise of water. Might rid the noise if post filter was removed, but this is inaudible in my specific situation. But great skimmer in all!!!!! Would recommend to anybody looking for a great skimmer for heavy or light bioload!!!

9410.00 - a real skimmer

Comments: I decided to wait a year before writing a thorough review on Tunze's 9410.00 protein skimmer. Here it is. Pros: Relatively quiet (motor and air production inaudible) Controllability on air to water ratio intake (for wet or dry skimming) Easy to clean (this is important people!!) Large collection cup (larger aftermarket available too!!) Low power consumption Built in overflow protector Extreme skimmate production (yes, extreme.) Efficient Skim memory ( if it looses power you don't have to tweak it) Customer service (bar none, class A service- another important one people!!!! do not overlook this!!!) Cons: Skimmate stinks (I guess this can be a pro?) Overflow water from skimmer can be noisy depending on water level ( there are tweaks you can do to decrease the sound) Collection cup seems frail (thinner acrylic, but so far no issues, be gentle handling it though) Larger footprint ( needs a larger sump-measure, measure!) Overall, I can see past all the cons as the pros outweigh them all, including the competition for its price point to value in the skimmer range selection of up to 264g. I use this on 150g mixed reef. Tunze is real toys for real reefers. Do your research, then get your credit card out and just buy it already, you wont regret it.

Comments: I am a beginner at this hobby so I have made some poor choices on equipment. When I purchased a $100 skimmer so I could save money, that skimmer stopped making bubbles after 4 months. I have been listening to and he had recommended this skimmer along with a few other ones that were a bit more expensive. I thought my old skimmer was doing such a great job when it was working then I put this skimmer in my sump. WOW!!! what a difference. After a week I pulled the collection cup off and it looked like tar. The smell was almost unbearable. I will say I would have liked it if the collection cup was a little bigger. I have to empty the cup about every 4 days.

Comments: Just like others have said the cup is a little noisy at first, i have had it running 2 weeks and it has quieted down. The pump prefilter was shoved into the standpipe out of the box and I didn't notice and it caused a few overflows and some frustration because of the extra back pressure, now that its properly assembled its working great. Even with the issue it was skimnming alot of junk out of my tank. I have had a tunze 9002 for 4 years with no problems so i hope this unit works just as well.

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.
