I'd put a 5 or even 1 micron sediment filter on the line in front of your house.
The city water here is 410-790 tds (average 580), but comes out at 330 at the tap
after passing through the 5 micron whole house filter in front. And they last a long time.
Then put a 0.5 micron sediment filter the 1st online in your unit.

update:
I am now getting better than 250 gallons of 0 TDS water from a DI cartridge, this will not help my RO membrane life, however I am getting very acceptable DI life

Hi Ballerina,
I think this is one of the best bang for the buck units out few for the price conscious consumers

It includes pretty much everything you will need to run for your tank (tds meter and pressure gauge included). Upkeep costs vary little between units and your best bet to keep costs down is to buy in bulk. I find bulkreefsupply.com to be excellent for buying replacement RO/DI filters. You will pay more upfront but the sediment and carbon filters will store very well. If you can get in on group buys in your local reef club, you can also buy DI resin in bulk and share with the group (DI resin does not store nearly as well). And welcome to Reefcentral.

The 75 GPD Premium from Buckeye is probably the best value today.
Prefilters and carbon blocks get changed every 6 months, the RO membrane should last 3-5 years or longer if maintained well and quality replacement filters are used and DI cartridges/resin are entirely dependent on your water conditions, your RO efficiency and how much water you make. Probably somewhere between 300 and 500 gallons is a safe estimate for a full 20 oz cartridge of quality resin.
RO or Reverse Osmosis is a process of passing water molecules through a semipermeable membrane or ultra thin piece of plastic film with microscopic pores in it. This removes 90-98% of the solids or contaminants.
DI or Deionization is an ion exchange process that attracts anything that is electrically charged for extremely pure water. DI by itself is not economical for most as it has a very short lifespan unless water is pretreated with RO. The combination of prefiltration, carbon adsorption, reverse osmosis and deionization is the best available technology.
