WTB DI Unit

Hi, looking for a 2nd hand DI unit, preferably something like the Crystal Pro one-cartridge one. I will consider all offers but cannot be forced to buy. Thanks

Bro,

DI filters in Singapore really don't work all that well, Singapore water has a high concentration of sediments that have to be removed first, I use a 0.4 micron Ceramic Filter (cleanable).

Second you need a carbon block filter to remove the (Chemicals, Herbicides, Pesticides, Bacteria, Parasites/Cysts and chlorine)

After the first two stages you'll increase the live of a DI filter... better is to use a RO system with the DI being the last stage before your tank, you increase the TDS reading from about 100G to as much as 1000G before you kill the DI resin.

Single cartridge filters will not be very useful in my opinion. The chlorine in the tap water will foul up the DI resin very quickly and the life of the DI resin will be shortened substantially.
