[charlie]

Hi

Is there any differences of water used for marine topup outputted from those drinking water purity faucet and DI unit? someone can advise? Thanks

If the purity thing is a RO unit, then the PH of the output water is abt 7.2 or thereabout.

If pure DI only, the output water PH is abt 8.3 (same as PUB water supply)

PS: Because of the PH of the RO water I use it to extract the calcium from a pail of ARM. After 1 day, the PH will adjust itself to 8.2. I then use this water for top ups.

This is just my own practice and not sure if it's proper, but so far (after 9 mths) I dont experience any adversed side effect.
