another RO/DI question

[apexifd]

this probably been asked before. but, I am going to asking again.

I am planning on ordering an RO/Di system from aquasafe this month for both fish tank and drinking water.

and I notice the home system only has 1 DI canister while the aquarium kit has 3. What are the difference of having 1 vs 3?? effect on drinking or fish?

thanks

Just water polishing. For drinking water 0 TDS makes water taste like air. Everyhing else should be taken out by the time it gets to the DI canisters, all that should be left is minerals. In drinking water haveing a small amount of minerals is not the end of the world, or unsafe. For a fish tank a small amount of iron or copper can be very bad.

been using their home system for years with only the single DI cartridge. Don't even think they has an aquarium kit when I bought mine. Can get 0 TDS with it.

As long as you can get 0 TDS, then the extra stages are just costing you money.

My guess is that not many people on Canreef have more than 1 DI stage.

I have no DI and I get 0.
