Thanks Ed. That's really good advice. My issue is the noise is getting worse and I'm worried of failure. And it's not a small amount of noise. I can hear it from my bedroom (small apartment).
Interestingly I have an IKS Vario Blue II heavy duty dosing pump for my ATO (rated for continuous operation). Its noise does not bother me as I barely notice it (whether it's the deeper pitch or just the lack of grinding).
Also, when splitting the dose with 'auto' in GCC, correct me if I'm wrong, but the dose can be split throughout the whole day into up to 150 doses? Only with manual dosing can I pick the times... but you can only pick it to run a few times per day in that mode?
I don't want to be dosing too much at once given my sps and small tank. The whole reason I got the GHL was to have absolute stability. If I wanted a handful of doses throughout the night while I slept, I could have just bought a jebao and been done with it. And I know the doser 2.1 can be quiet. When I first got it, I could sit next to it and barely hear it run as it dosed 0.3ml 150x a day. Now i have reduced its frequency by increasing my dose at the moment per event to 1ml 55x. Again, not something I expect to have to do given the way it's marketed.
There is a Neptune Apex distributor in NZ, so a DOS is an option, but I somehow convinced myself, given my german heritage, that the GHL doser would have been better after reading how noisy the DOS was.
If only I had got a doser 2 rather than a 2.1. Those seem to have few issues.
