I would suggest starting out with an RO with DI. Don't upgrade later.

This is the RO/DI unit I have and have had for nearly 3 years. I buy my replacement filters from the same person. I am very happy with this unit. There are a lot of them on the market but that is what I use.

A lot of folks here to their RODI unit on eBay. I got a Typhoon III several years ago from AirwaterIce. They reccomend a 10 micron sediment cartridge followed by a 5 micron charcoal, then a 1 micron charcoal. This leads to the RO membrane which is then followed by the DI carridge. I now use the DI Refillable kit. I can always get a new sediment cartridge at Lowes or HD if I run out, but the cost from AWI is less.

When I replace my membrane I will get the new 150gpd that they have which also has a 98% rejection rate. The 100gpd only has a 90% rejection rate and is not recommended for reef (leaves too much for the DI to handle).

I also prefer the clear cartridges so I can see how dirty the sediment filter is getting.

I have one like Allen and cmor have and I also would recommend an RO/DI unit. They are well worth the investment. I also second not getting the water off the beach. Usually too contaminated. BTW welcome to AA
