I thought I would just add my experience of this product:-
I bought the 18W version and am pleased to say that after assembly into the system it didn't leak. In fact it worked beautifully and cleared all the suspended algae, 'pea soup' and the tank looked crystal clear within a month. The tank had been getting progressively worse and it didn't seem to matter how little light or what I did it continued to get worse, hence my going down this route.
Unfortunately after a month the unit stopped working, the red light went out and you could see that the UV bulb was out. I tried unplugging the unit and plugging it back in and it worked, but only for a short while. It eventually failed completely.
I wrote to the supplier and they suggested I dissassemble the unit and check that water has entered the inner chamber and got into the electrics. I did this and confirmed that the electric part of it was bone dry. The supplier then suggested a new bulb which I tried.....to no avail.
I have now concluded that the power supply has failed. Very dissappointed as it only lasted for around a month and now 2 months on my tank is going back to 'pea soup'.
Anyone know what power supply is required as I have various ones kicking around that I may be able to substitute. I'm also looking for other manufacturers and in particular one where I don't have to mess around draining my filter pipes down etc., to replace the bulb!
TIA
