Cost effective / practical ways to lower TDS/PPM for resevoir solutions

If you have any suggestions on cheap ways to filter tap water and keep your TDS/PPM level low please post them here.

Currently I use britta water filters to lower the PPM of my running tap water from 210 down to around 100, +/- 20

I mark my reservoir with a line at 12 gallons and use tap water passed thru the britta filter to fill it up. Once I hit the line, I begin to scoop the water in the reservoir and pass it through the filter again and again until the pH of the resevoir reads 5.8 pH. The more you pass the water through the filter, the lower PPM and pH of the entire solution will be.

This obviously takes a long time but in theory you could make use of multiple filters to speed the process up. Doing this, I have found that the pH and PPM of the solution is very stable even after nutrients are added.

Does anyone have any other tips or tricks to stabilize nutrient solutions?

One thing I had considered was making my own filter using the same contents that britta uses, just on a larger scale and hopefully cheaper.... does anyone know anything about this?

210 is not that bad. Part of that ppm is calcium, magnesium, and things you'd need to add anyways.
most cost effective way is to use tap water and save money by adding less nutes.

as long as you're not using well water or something, you should be okay.

Losing plants to major pH fluctuations is not cost effective. It's alright if anyone else wants to risk it, but for my situation and the results I have seen so far, filtering the tap water in my area is a must. The britta filter is a short term solution which has proven to be very effective so far. My thoughts are leaning towards a RO system or finding an easy way to construct my own filter, but thanks for your considerations.

Not sure what nutrient line you are using but I've never had a Ph problem with Dyna-Grow nutrients to the point where I forget to test it weekly. Someone suggested it was the silicon in the Pro-Tekt that made the Ph so stable.

I think there are many other nutrient brands that are ph stable meaning their natural tendency is to settle at an ideal Ph of around 5.8 for hydroponic mediums. My personal experience is with botanicare c17 nutrient line and with GH (both Lucas and normal). Both of the lines mentioned previously had to be adjusted periodically (2-3 days) for the Ph to remain where I wanted it.

Brita is the cheapest "partial fix" I know of. I'm buying distilled now, but plan to add a R/O soon.
Amazon has some as low 160 bucks...wouldn't take too awful long to spend that at Walmart on distilled.

I'd personally celebrate water at 200 ppm...lol. Not because it's so good, but rather my water is just so damn bad. I'm on a well and can see (1000-1200 ppm) thousands of particles in a glass of water.
It's so bad we never drink it unfiltered and the refrigerator water filter needs replaced in under a month.
