Aquasana Vs. RO/DI

[ItsAName]

I have an aquasana system in my home (http://www.aquasana.com/whole-house-water-filters/600k-gallon-rhino) that removes chlorine with a pre filter (5 micron filter) and post filter ( 0.35 Sub-Micron Filter). Do I still need an RO/DI system?

I would test it with a tds meter and see how it comes out. If it's 0 then I'd think it's fine.

I think your house filter is approximately equivalent to the prefilters I use before my ro filter. The purpose of the prefilters in this set up is primarily to remove the largest particles to extend the life of the ro filter. The ro filter is where I'm getting the bulk of the benefit from. The DI resin is catching whatever makes it past the ro.

If you are going to keep coral there's s chance your house filter won't pull everything it needs to. If you are keeping a fish only tank it may be sufficient, but still may not. I noticed chlorine is removed at a rate of 95% which could be problematic even in a fish only tank.

FWIW, I find some of their claims to be exaggerated. Look at the scale prevention "simulation" pictures. Even the outside of the untreated pipes are corroded, and the ones using this "method" are not even tarnished outside. lol
