TUNZE
PROTEIN SKIMMERS
NEW STYLE DOC SKIMMERS
IN OUR OPINION THESE ARE PROBABLY THE EASIEST
TO USE AND MOST
PRODUCTIVE SKIMMERS ON THE MARKET FOR SALT WATER MARINE HOME AQUARIUMS. WITH A
VARIETY OF MODELS TO SUIT MOST AQUARIUMS ,IF YOU ARE NOT SURE WHICH ONE WILL BE
THE MOST SUITED TO YOUR NEEDS PLEASE DON'T HESITATE TO CONTACT US FOR ADVICE

Marine aquarium inhabitants produce waste
substances, the quantity depends on the livestock and the feeding. By
means of an effective skimming system, organic waste matter, the
so-called DOCs (Dissolved Organic Carbons), can be removed. To mention
but a few, these are substances such as proteins, cellulose, dead cell
substances from bacterial and algae. In high concentration they are
harmful for any aquarium biotope. The DOC skimmer removes these
compounds effectively from the water circuit, better than a
bio-mechanical filter, which means that by removing proteins
“before” bacterial decomposition, crystal-clear water is retained
and a rise in nitrate and phosphate is reduced.
It can be observed that when air bubbles are produced proteins are
absorbed immediately. In practice it can be observed that the absorbed
matter is torn off the air bubbles again by skimmers with a tall
reaction chamber. For this reason, all TUNZE® DOC skimmers have
very short reactors with a high air throughput .
|
Principle
In the skimmer, the TUNZE®
Hydrofoamer produces a large quantity of a mixture of 50 per cent of
water and 50 per cent of fine air bubbles. Each air bubble has an active
surface which binds the electrically charged DOCs (Dissolved Organic
Carbons). The air water mixture is immediately transported into the
middle reactor area, producing a dense foamy mass. The upper zone of the
reactor is used to settle this foamy mass laden with protein, which is
then removed into a special foam cup or into the foam extraction pipe.
The purified water returns into the aquarium without bubbles or into the
filter. By means of a special nipple, ozone can be introduced into the
system, thus improving the skimming process and at the same time
removing any yellowing matter in the aquarium water.

Nano DOC skimmer
The “Nano” model series has been designed for the use in reef
biotopes up to 200 litres (44 UK gal.), and is gentle to the plankton in
operation. Very little space is required in the aquarium, and its
handling is very easy. On account of the high demands in stone coral
aquariums, this skimmer should be used only in aquariums with about 100
litres (22 UK gal.) of water. Mixed aquariums or soft coral aquariums up
to 200 litres (44 UK gal.) can be set up without any problems.

Classic DOC skimmer
These skimmers operate according to the
horizontal rotation principle and are driven by the Hydrofoamer.
The entire skimmer operates on the basis of the so-called
contact skimming method. For this reason, coarser particles in
the size of plankton are not drawn in. This method of operation
is very gentle so that no living plankton is drawn into the pump
circuit. The extremely flat construction makes it the smallest
skimmer in its performance class.
Low sensitivity
In soft coral aquariums with leather 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.
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. The Classic DOC skimmer
should NOT be 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 for breeding tanks with plankton
Stone coral aquariums or other breeding tanks with plankton food
require an especially high degree of purity. Good oxygen
saturation and very clear water are the pre-requisites. This
type of aquarium should be reduced by about 60 per cent in
volume for the skimmer volume mentioned. |

| COMLINE
STYLE |
The
model series of the Comline DOC skimmers has been developed for
an effective and modern protein skimming process in marine
biotopes from 200 to 2,000 litres (52 to 528 US gal.). They
stand out for their compact dimensions at the same time ensuring
a high foam cup capacity, and producing a very high throughput
on account of their air capacity of 650 or 1,300 l/h (171 or 343
US gal./h), for example, depending on the model. They can be
placed directly in the aquarium or in cabinet systems with a
variable water level.
General information
At an immersion depth of 240 to 290 mm
(9.4 to 11.4 in.), the Comline DOC skimmer models can be placed
easily and discreetly in the aquarium directly. The inlet of
fresh water can be set at between 5 per cent and 70 per cent.
They can also be used in aquarium cabinets with variable levels
from 100 to 280 mm (3.9 to 11 in.). The accessories supplied
have to be used to ensure the generation of a constant internal
water level. The water circuit is totally open and operates at a
fresh-water inlet of 100 per cent; depending on model, a water
throughput of 1,200 l/h or 2,400 l/h (317 US gal./h or 634 US
gal./h) is achieved, distinctly improving the gas exchange in
the aquarium.
In case of operation in aquarium cabinets, the cartridge core on
the outlet pipe ensures bubble-free outgoing water. Skimmer cup
and foam reactor are one unit in all TUNZE® DOC skimmers. Every
cleaning of the skimmer cup leads to the reactor being cleaned
at the same time, and thus a very constant and efficient foam
production is ensured. During the cleaning process, the
Hydrofoamer remains operational and automatically flushes the
jet and the air passage.
Delivery condition: Completely ready for mounting with numerous
holding devices like in Comline Filter or Reefpack 500
