If you just installed your system or replaced your filters, a little cloudiness is completely normal. The cloudiness is tiny air bubbles. Within a week or two of normal use, the air trapped in the system will be gone and your water will be clear.
If you want to get rid of the air faster please flush the system for 7 minutes over 3-4 days.
Some people also have high water pressure and don't open their AquaLiv faucet fully. This 'throttled flow' causes cavitation which also creates air bubbles. Simply opening the faucet fully will solve this problem.
