New to 2021, the D-D range of pure titanium heaters is available in four new sizes to suit all marine, reef and freshwater aquariums.
D-D Titanium Heaters are manufactured in Germany from high-quality components and are shatterproof, saltwater proof and virtually indestructible, a high-quality product, built to last. These heaters are fully submersible and feature a continuous titanium jacket, thanks to the newly designed internal earth connection.
Titanium is completely non-corrosive in saltwater and one of the best conductors, delivering heat to aquarium water substantially better than conventional glass heaters, for more efficient running.
150mm W 250mm x 25mm (L x W) For aquariums up to 150 litres.
250mm W 250mm x 25mm (L x W) For aquariums up to 250 litres.
350mm W 250mm x 25mm (L x W) For aquariums up to 350 litres.
650mm W 350mm x 25mm (L x W) For aquariums up to 650 litres.
Suction Cap Material: Neoprene.
Cable length: 1.5m.
Electrical connection: UK Plug 230v 50Hz.
NOTE: D-D Titanium Heaters do NOT have a thermostat and therefore require a suitable temperature controller such as the TC125 to regulate temperature.

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.
A heater in a fish tank is used to maintain a consistent, appropriate water temperature for the fish and other aquatic life living in the tank. Different species of fish have different temperature requirements, so it's important to ensure that the water temperature in the tank is within the appropriate range for the specific type of fish you are keeping.
In general, most tropical fish need a water temperature in the range of 24-28 degrees Celsius. Coldwater fish, such as goldfish, may prefer water that is slightly cooler, around 20-23 degrees Celsius.
A heater in a fish tank helps to maintain a stable water temperature by using an electric heating element to warm the water. The heater is typically placed inside the tank and connected to a thermostat that measures the water temperature and turns the heater on or off as needed to maintain the desired temperature.
It's important to monitor the water temperature in your fish tank regularly and to adjust the heater as needed to ensure that the temperature stays within the appropriate range for your fish. If the water temperature gets too cold, the fish may become sluggish and inactive, and may be more prone to illness. On the other hand, if the water temperature gets too hot, the fish may become stressed and may also be more prone to illness.
