Im following this thread, I need to know of a good RO/DI unit for my set up as well that wont ruin the bank.

 

If you have a 50 GPD or less RO/DI system an Aquatec 6800 will work great. If your RO/DI is 75 GPD or greater you will need to Aquatec 8800.
Be careful when shopping for booster pumps, some vendors sell the pump, 24v DC power supply and pressure switch seperately to make the price sound good and you don't realize it until you get a pump with no power supply.

There are imported clones on the market but I would shy away from them, just like most all RO/DI components, you really do get what you pay for. The 8800 with a power supply and pressure switch will run you around $125-$150 complete. Some of the people who carry them are SpectraPure Water Purification Products, www.buckeyefieldsupply.com, RO DI | Saltwater Aquarium Water Filters | Reverse Osmosis Booster Pump to name a few. I think Purely had the best price last I checked.
Aquatec 8800 pump Good deal at $100 for the pump and power supply and $24 for the pressure switch.

A RO/DI unit usually consists of a sediment filter, a carbon block filter, a RO membrane and a DI filter. Along with that there are the housings they all reside in, the bracket that holds it all together, assorted fittings and tubing, a flow restrictor and a pressure gauge.

Here is an article that explains what each does:
GENERAL INFO ON REVERSE OSMOSIS

 

For comparison purposes. BRS also sells decent units that won't break the bank

 

More money than PurelyH2o unless you get it on a group buy discount.

 

So you need a pump and an ro/Di unit?

For a normal RO/DI no as long as you have 40 psi available to the RO membrane. A booster pump will improve any RO membranes GPD and rejection rate but they will operate at 40 psi to 100 psi just fine without one. The highet the pressure the better it will perform.
