Tunze Protein Skimmer 9010

[Blenny]

did you purchase this unit from Reef depot. Am considering the 9020. any advise

[Tigger]

I am impress by this skimmer. Small but power.

[FuEl]

Wow looks like foam formed in a bubble bath.

[Eudaceous]

Just to answer Blenny's question. Yes I purchased this from ReefDepot. The 9020 model is the same in terms of horsepower / wattage / air-water intake etc compared to the 9010 yest it is close to $700.. The only difference is that it has a bigger collection cup.

Originally I planned for the 9020 for my 5 footer, but scaled down to the 9010. Its the economic argument...without compromising on the skimming capabilities. Also the 9020 needs a taller height clearance. You can see my sump is pretty compressed already. WIll be happy to assist you if you are getting one Blenny....

Regards

wow...the foam head really looks pretty good! Assuming you're having fun Eudaceous? bubble bath? anyway good to hear you're accustomed to using ozone. Post pics when the skimmate starts collecting yeah? hmmz...now wondering whether worth it to use a 9002 or 9005 in a 2ft...

[Blenny]

am curious why the 9020 top portion is different from the 9015. the latter have a foam collection cup bot 9020 seems to be some kind of piping. How' sthe skimmer doing today. any more pics. thanks in advance

Choosing A right Tunze for yourself (snatched from Tunze homepage)

The Comline DOC skimmer with hydrofoamer has an open water circuit which can be controlled. Apart from the air output, the flow rate of the skimmer determines the output of the DOC skimmer. In addition, due its biotope composition, every marine aquarium has a different sensitivity with respect to the organic load. Based on a standard marine aquarium with soft corals, the data on the suitable skimmer size may differ in other biotopes. For this reason, the aquarium volumes recommended for the skimmer should be reduced in case of sensitive biotopes:

Low sensitivity

In soft coral aquariums with long-polyp corals and anemones, for example, the share in dissolved organic matter may be higher, sometimes it may even be vital. In this type of aquarium, the recommended aquarium volume can be used without deduction.

Medium sensitivity

A medium organic stability is usually found in mixed aquariums inhabited with soft and stone corals (LPS). Filter-feeding animals, sponges, et cetera, are found there frequently as well. For these aquariums, a reduction of about 20 per cent of the skimming capacity is calculated. A skimmer for 1,000 litres (264 US gal.) should thus be used for an aquarium of about 800 litres (211 US gal.) which has this kind of reef design.

High sensitivity

Aquariums with primarily small-polyp stony corals (SPS) require an especially high degree of purity. They should have no load of phosphates or nitrates worth mentioning. Good oxygen saturation and very clear water are the pre-requisites. Comline DOC skimmer is also often used as a “stand-alone” solution in these aquariums. This type of aquarium should be reduced by about 40 per cent in volume for the skimmer volume mentioned.

High sensitivity and high load

Hard coral aquariums with a high population of fish require an extremely high skimming capacity. The skimmer has to ensure the degree of purity for the hard corals at an above-average high fish load. If the Comline DOC skimmer has to operate as a “stand-alone” solution here, a high performance is required. This type of aquarium should be reduced by up to 60 per cent in volume for the skimmer volume mentioned.

Tunze 9015

Yes this is a bigger skimmer compared to the 9010. The tech specs are as follows

Recommended for aquariums up to 1,500 litres (396 US gal.) of salt water.

Dimensions: L125 x W113 x H478 mm (L4.9 x W4.4 x H18.8 in.)

230V/50Hz (115V/60Hz) 21 W,

Water throughput: 1200l/h

(171 US gal./h)

Air capacity: 650l/h (171 US gal./h)

Skimmer cup volume: 1.4 l (.36 US gal.).

Equipped with the accessories for internal and aquarium cabinet operation

__ As you can see it differs only in terms of skimmer cup volume, mine is 0.7 l. This is almost double. The rest remains the same

[Eudaceous]

Tunze 9020 ( Mother of all Tunzes)

Recommended for aquariums up to 2,000 litres (528 US gal.) of salt water.

Dimensions: L125 x W113 x H460 mm (L4.9 x W4.4 x H18.1 in.)

230V/50Hz (115V/60Hz) 42 W; water throughput: 2,400 l/h (634 US gal./h); air capacity: 1,300 l/h (343 US gal./h). Comprises two reactors for removal of foaming water. Delivery in storage container 5002.25 (can be used as skimmate collector), with 2 x 40 cm (2 x 15.7 in.) drain hose and accessories for the operation in aquarium cabinets. If the collector is far below the skimmer, we recommend 2 x 1075.2 accessories.

The top is what tunze calls foam extraction unit. It will pull the skimmate downwards towards a cup, or mineral water bottle just like what a beckett does.

chiooo!!

Anyway I have been using Ozone for a while so I understand the impact of this gas on skimmate. What I like about Ozone is that it helps corals from contracting RTN (Rapid Tissue Necrosis). Yes it also significantly dissolves (DOC) and this reduces the Kopi-O colour o fthe skimmate.

Does this mean even though the color of the skimmate is not so dark when using the ozone, in net efficiency in removing DOC (total ozone + skimmer) is still as effective or reduced?

Yes that is the million dollar question that I want to discover. Previously on my weipros my skimmate is light brown...managed to keep NO3 to below 10....with this skimmer...not very sure what the outcome will be..but definitely anyone who uses Ozone will experience a lighter skimmate coz Ozone paritally breaks down DOC (Dissolved Organic Compounds - lifestock waste matter, plants cellulose and uneaten fish food) hence giving less work for the skimmer.

In short if you use Ozone, you are lessening the work for your skimmers. But for this Tunze, there indicated in teh amnual that it will enhance skimming provided you use very little, in accordance with your tank water volume. But still they reminded that skimmate will be diluted.

Am still enjoying your review and your generosity to share infor. Any idea if we can get hold of 9020 in S'pore. Thanks

can check with our sponsor reefdeport..

they are bringing in some even though the website does not reflect the sale

[somebody]

wonder when someone would sell their tunze. then i can buy second hand... =( can't afford a brand new one.

[Eudaceous]

For those who are interested

This is the collection cup and skimmate quality after 42 hours of firing. I notice the candy floss bubbles went down siginificantly last night at arounf 2300... I can see the bubbles at the lower end of the collection cup. I have tuned the skimmer to produce a dry foam.

[Eudaceous]

Another angle of the skimmate. Looks like Milo not really Kopi O....but remember me on Ozone...so actual skimmate without Ozone may potentially be darker

[Eudaceous]

My Sump... yes I have acquired a few goodies over the weekend..Added extra chamer of FR500 with Rowaphos + CR from AM.. You can see where the Tunze sits relative to the rest of the equipement. My chiller is at the right..also located within the sump.

[Eudaceous]

My pride and joy..may consider changing my Avatar to this...

[Eudaceous]

My five footer... have done a 40% monthly water change..corals look more alive and fish more tranquil....

[dreamzcape]

eud care to try without ozone and see the results? 42 hours of firing...looks like the breaking in is pretty short..and yea it looks like milo!

[somebody]

looks good to me.. =)

maybe u should off your ozone and post pic here.

[Eudaceous]

Hi guys (FYI) ...the Tunze 9010 is now firing without Ozone. Will post more updates soon

[somebody]

looking forward to seeing kopi-o being served. haha
