good work.
but I need to know where to get one in NZ
How often do you all claen youe return / CA / Skimmer pumps and when you do how do you do it?
Mine are coming up 12 months in a few months for my new tank... I like the idea of doing nothing but I'm sure there is a better option.

Good haviong a large water supply under the house.
