I had an ‘issue’ with my tank water quality after that big dust storm. It was very murky. I installed a two-stage water filter from Bunnings. Cost $102. Very successful. The standard unit is a 5 micron sediment filter followed by a 5 micron carbon filter. The standard of the filtration seems to improve after a few days. My water is now clean and bright again. There are a range of filter cartridges available. The finest is 0.5 micron. But the standard cartridge seems to be doing the job. It is a fairly simple installation, particularly if you already have a dishwasher faucet.
This is an under-counter installation with a drinking water tap that can be mounted on the sink or benchtop.
