it is generally known that Dupla equipment is extremelly overpriced
but I was curious of its value in Singapore. Where do you get it from? In
relation to your problem : I have the same controller and havent had a
problem. The only thing I can think of is that perhaps you have the wire to
the probe too close to the lighting circuitry. Have you tried moving it,
perhaps to inside your cabinet??

I am from Kuala Lumpur, Malaysia. Where the temperature would
be likely in the range of 32 - 34C.
I have a 200l tank. Duplaflex 300 heating cable with 2-3mm
gravel. The heating cable being controlled by Duplastat 300.
Water at 4KH/5GH 6.8pH. pH being controlled by Dupla pH
Have ordered Dupla's dosing pump 3 days ago from Dupla's agent
in Singapore. Lighting consisted of Arcadia 150w MH Pendant
1) My C02 controller is very sensitive to the switching on/off
of the house flourescent tube. When the controller is
injecting C02 with the red LED on, and then someone switches
off a light, the C02 controller will follow suit. Have tried
to use voltage stabilizer on the controller this morning but
with no effect. Any idea?
