Have you checked your RO/di to make sure it is still functioning
correctly? It sounds like your DI is exhausted and possibly your RO is
not working correctly also. Silicates are very hard to remove from the
water (hence the Kent silicaMAXX ro/di systems) so you need to make sure
your DI is fully charged and keep it that way to keep the silicates
undercontrol.

Thanks Kim, Can u tell me what I need to do to check it? is it just a matter
of replacing the Filters? or is there more

It sounds like you need to replace the DI unit and the sediment and
carbon filters, as for the membrane you can test it. Test the
Alkalinity of the tap water and the alk of the water out of the ro/di
unit. The alk of the ro/di should be very close to zero if it is not
the membrane is bad also.

Sounds like there is no DI,, just a 3 stage, (pre, carbon and a membrane.) DI
will remove silicates tha RO leaves behind. Diatoms fed on silicates.
A DI add on can be purchased for about $50

The filters say on the out side CARBON 1 CARBON 2 and SENTIMENT so
replacing the filters should do the trick?
