RO, should it be DI also?
I use RO water for my top off. I have fish and LPS as well as lots of zoanthids.
Is it worth having DI also? |

Yes it is. Depending on what RO membrane you have, you are removing 90-98% of the TDS from your tap water, the DI will remove the rest.
How long the DI resin last will depend on your starting TDS, and how efficient your RO membrane is.

I would get a RO/DI would be best for the purest water.

Agreed with the others, and adding a DI chamber is pretty easy. I'd put the money into it.
