Wet Skimming on Tunze 9005/9010?

[Kinetic]

I am very interested in purchasing a tunze 9005 or 9010 for my 68 gallon tank I'm putting together, but I keep hearing they skim wetter than most skimmers with similar ratings.

I'm considering an Octopus DNW-110 and a Tunze 9005 for a skimmer, and I know that tunze is smaller and quieter, rated better, but is it going to be as efficient as a darker skimming dnw?

I may be lead to wrongly believe that tunze skims pretty wet?

Roger: which skimmer would you recommend between the 9005 and 9010 for a 68g display with a medium sps/fish bioload?

And if people can post pictures of their skimmate in the tunze skimmers, that'd be great!

I really want to get the tunze!!

tagging along I am also looking at tunze skimmers for their small footprint. worried about TOO wet skimming

They do skim wet when set up right, this is preferrable as it removes more phosphate and skims more reliably. If you set it to skim drier, which you can do, the skimmate cakes up on the riser and breaks the bubbles dreducing efficiency, the wet skimming is really the better way to go, my skimmate generally looks somewhere between tea and light coffee. If you will have a sump, 9010 is the best way to go, in tank the 9005 is fine but it doesn't include the sump kit and by the time you buy that it is only about $25 more to get a 9010 with the bigger pump and cup.

is there any reading material about what the foam extractor does?

I'm probably going to go for the 9010 for 68 gallon SPS tank into a 30 gallon sump =)

roger I spoke to someone who has their screw all the way to the last tooth out on their 9010. it was my understanding that the 9015s cup was what allowed you to do this? however this person has the 9010 cup. just kinda scares me away from the 9015 because of the possibility that I might not be able to skim as efficently

 

[rvitko]

I would suspect that the person with the screw all the way out has something installed wrong or there is something obstructing the venturi.

The foam extractor is just a riser tube with a drain at the top of an incline instead of a cup, the foam drains off down a hose into a bucket.

oh i see, so it's just a replacement for the cup and doesn't affect skimmer operation?

 

[rvitko]

No, no change in operation other than the skimmer is a bit stronger as more air can be mixed in.

I have the 9015, and I'd like to replace my cup with the one from the 9010. I can't skim wet with the taller cup. Now, admittedly I don't have much to skim right now as my fish have been in quarantine since I put in the 9015, but even wide open I only get foam about 3/4 up the neck, and most of the gunk collects there. At most I'll get maybe 1/8 inch of liquid a day in the cup itself. Fortunately I'm able to clean it each day without too much trouble.

But like I said I've had no fish in the tank since adding the 9015. Maybe after they're back I'll see more active/wetter skimming. But if you're lightly stocked then I think it's a valid concern that you'll not be able to skim as wet as you'd like with the 9015.
