This question makes no sense to me. My understanding of water softeners is they replace Ca2+ and Mg2+ with Na+ ions. This type of water softener doesnt produce anything remotely similar to pure water, its just replacing one salt with another. (Not to mention, I have never read anything to suggest they remove Cu+/2+ which is present at toxic levels (for invertebrates) in many or most sources of tapwater. (Nearly all homes have copper pipes, after all)

Is there some other kind of water softener I am not aware of that is actually removing ions rather than just replacing them?

No. I ran my water on solenoid before a pre filter and in a few days it stuck open. Total bone head move ion my part.

never trust house water or its plumbing, always run a pre filter directly on front of your carbon and RO membrane, its why the sell them that way

They are always a must.

I run a booster pump after prefilter and carbon blocks, solves that.

Nope - your understanding of a typical residential softener is right on.

I often hear homeowners with troublesome water say something along these lines: "I just don't understand it.. I installed a whole house filter but I'm still having bad water issues..."

When we do a little digging, we find the "magic" multi-blah, blah, blah filter is little more than a sediment filter, or some other generic/off-the-shelf type of media that doesn't really address the real water quality issue(s).

I'm thinking most people don't really understand that 90% of the plumbing in the US is COPPER pipes which we all know is bad for our tanks even in small amounts.

Regardless of whether he has a whole house softener or not, I'll bet the house is fed with copper pipes. This does assume it's an older house and not fed by PEX or CPVC pipes.

Yep - likely copper or PEX.

If PEX it's probably fine(even though most PEX fittings are copper). I would not trust it and still run an RO/DI. My entire house is PEX(replumbed myself a few years back when copper was sky high in price), and even still with the few copper PEX fittings I still run an RO/DI.

Give Buckeye Hydro ^^ a call, they won't steer you wrong, and certainly won't sell you something you don't need.

After being on these boards for a while now and seeing buckeyes replies, if I hadn't bought an RO/DI from BRS, they would have been my first call had I known about them.

I love seeing this response. I successfully kept reefs for many years before I was able to purchase an ro/di unit using the dreaded tap water, fortunately my city tap water wasn't horrible for it. I also made sure I ran my water for several minutes to clear any copper concentration from the water that had been standing in the pipes. Most plumbing before the house is steel/iron and tap waters are generally balanced to NOT corrode the pipes so harmful metallic concentrations are generally lower than people think.

one of the secrets to using tap water or less than "pristine" starting water is to do less top offs and more water changes. the reason follows, as you top off any trace concentrations are going to rise through top off and evaporation. by replacing top off with water changes you are removing it reducing the rate at which it climbs. also running media in your system designed to remove such nasties like chemipure elite can help moderate the negatives generally associated with tap water.

now as to the OPs original question I would be more likely to use the water before that home filtration than I would be to use what was filtered through it.

I'n the long run Ro/di is definitely a less hassle and safer route if trace/mineral content of the source water is questionable.
