Where in victoria can you get RO water?

[Squinch]

Long time reader first time victoria forum poster, Hey now.

Anyway is it just me or is victoria tap water hurtin from all this warm weather? Im using a under sink dual filtration unit but it cloggs up with crap in a few weeks. My discus are hurtin units and my hair algee in my reef tank is unreal! My hermet crabs all are sportin a full head of hair and my rock is getting gross in the green. It can't be good for my corals eather, but what can I do?

I was thinking A few large water changes with RO water over a few weeks might help? Anybody know where I can get some?

Thanks
