Suitable for aquariums up to 1000 lts (220 UK Gallons).
Deltec's innovative TC-PRO (Twin chamber) range of external protein skimmers featuring Deltec's high performance pump with class leading energy to air ratio.
For over 25 years Deltec GMBH have worked hard to develop the best specialist marine aquarium equipment available on the market. They are known throughout the world for the high performance and quality of their protein skimmers. When their patent on the Deltec Pinwheel ran out it opened the market for other people to copy their ideas and to produce pinwheels of their own but without the 25+ years of experience and development that had gone into the Deltec products.
The latest generations of Deltec protein skimmers have been developed to produce the optimum air to water ratio in the reaction chamber for the lowest possible power consumption.
The TC name describes the special Twin Chamber design of the bubble chamber which is patented and has the benefit of pressurising the pumps for higher performance and ensures that only unskimmed water passes through the pump rather than reskimming and reprocessing water in the chamber.
The bubble plate design allows the height of the skimmers to be reduced and allow them to fit in a cabinet. The primary use of the bubble chamber is to prevent turbulence from the skimmer body and neck as turbulence can pull waste loaded bubbles back into the water column causing a reduction in efficiency. The air to water ratio is so high that there is almost immediate reaction with the waste therefore there is no requirement for the tall reaction chambers found on some low air skimmers thus keeping the units compact.

The sensor on the DDATO has different light colours and patterns to warn of faults or show its status.
Flashing blue and red LED. The unit has been powered on and it is going through its startup process.
Flashing blue LED. A low water level has been detected and the top up unit is operating the pump to refill with fresh water.
Short intermitting blinking blue LED. The waterlevel is above the failsafe sensor and the unit has been temporarily deactivated. When the water level returns to below the emergncy sensor the unit will return to normal operation. The failsafe sensor can be activated after each top up on nano aquariums, this is normal and no action needs to be taken.
Solid Blue LED. The top up unit is in normal standby mode.
Flashing red LED. Alarm mode has been activated. The unit has detected an issue and or the freshwater reservoir is empty.
Why is my D+D ATO sensor light red
A red light on the sensor can indicate one of these things.
The sensor's inbuilt emergency shut-off timer has been activated
When the unit performs its first top-up after being powered on it will store the time taken in its memory. If for any reason the top-up unit is activated for longer than 6 times this the sensor will assume there is a problem or that the freshwater reservoir is empty, shut down and show the red warning light.
Corrective action to set the ATO back into normal operation mode and clear the alarm status, power the unit down from the mains plug socket for a few seconds and then power it back up. The sensor should flash red/blue a few times as it reinitialises and then returns to normal operation mode with a solid blue status light.
The sensor is detecting a fault with the ATO pump.
If the pump cannot run the sensor may go into alarm mode and turn off power to the pump. If this is the situation you will notice that when the top-up activates the pump will not turn on and the status light will immediately show red and not flash blue until time out occurs.
Corrective action:_Disconnect the unit from mains power, check that the connector where the power lead and pump plug-in has not become wet and that the impellor in the pump is clean and free to move.
The freshwater reservoir is empty or the sensor is impaired
No water in the reservoir or microbubbles in the water are causing issues with the sensor detecting the water level. Check that the sensor is not in an area where it is subject to small bubbles, eg near the outlet from a skimmer.
Corrective action: If this has occurred check that the sensor is clean, the impellor in the pump is clean and free to move, the freshwater reservoir is not empty, and there is nothing that could be causing the sump water level to fall unexpectedly.
