We have a Rain Soft system but that was around $5,000 and a unit like that would probably not be ideal for an apartment setting.
I went on eBay and typed in "water softener". I found this thing called an "Electronic Water Softener". It looks like it may work for your situation.
Here's their description:
Tired of hard water lime and calcium build-up? Tired of dishwashers covered with nasty calcium deposits and dishes and silverware that never get clean? Tired of build-up that increases the amount of soap you need to wash cloths or even take a shower and still not feel clean! Tired of paying for and carrying heavy bags of salt for your water softener? Well, here is the answer - Water Zone - The electronic answer to the build-up and deposit of minerals in you water system! Very simply, most water supply from well water or municipal sources has water loaded with minerals that are "sticky". Minerals that stick to every pipe, every dish, your water heater and even your skin. Our Water Zone "Electronic Water softener" treats your water so the water particles become "slippery" and do not stick! The mineral content of your water is exactly the same - no change what so ever except, the molecule is now "slippery" and doesn't get deposited but flows on thru! Includes 110 volt plug in "trickle" unit! Can be uses on PVC, Copper or galvanized pipes!
Don't load your system up with sodium from traditional water softeners, use our "Green" Water Zone and keep the environment clean and safe. Uses just a trickle of electricity. Unit is super easy to install, no pipes to cut, comes with full instructions - Your water can be on it's way to cleaner use within 15 - 20 minutes - Water Zone will increase you water heaters efficiency and comes with a 100% money back guarantee, if you are not satisfied "For Any Reason" - Just return for a full refund less the shipping charge.

If you have rusty/brown stains which look like this type and build-up around your basin or toilet bowl Water Zone will also help in this area. If your stains are coming from rusty pipes or the mineral content in your water Water Zone will reduce this by 75% - 90% possibly more! If you are cleaning these stains every week Water Zone will reduce your cleaning to once every four - six weeks and maybe even longer! Give us a try - If you try Water Zone for three months and aren’t satisfied and your unit isn’t damaged, just unhook it and return for a full refund less shipping.
