Ok so I am looking at buying a RO/DI system

Just wondering for the future.

I'm looking at RO/DI models right now.

For a 20 L tank that is being cycled at the moment for a saltwater environment,

I just need one of these model systems that goes through four stages of filtration, which includes the DI?

Secondly, I think I only need one of these models that just produces 25gpd

GPD means gallons per day?

Since first my tank can hold max 20 gallons, and when I do future water changes I only plan on changing 25 or max 35% of the water at a time.

Check out the marketplace for an rodi unit. A 25-50g should be fine. If you think you'll upgrade sooner than later is go for at least the. 50gpd

more gpd = faster pure gallons per hour

So I am wondering, the more gpd the faster pure water is made from a ro di system?
This might seem obvious, but i am not sure if the rate would be increased with a more gpd system or just that a more gpd ro/di system would be capable of producing more in a day?
