Terrible water here in San Diego too. I'd definitely recommend going with RO water and remineralizing. I make little bottles of concentrate and add them to a 5 gal bucket with flojet. Works great.

I'm in Jax as well. I went with a RO system from SpectraPure. I then use a flojet with a 5 gallon jug with TWW packets.
Interested to see what you end up with!

Finally got around to checking my ESO-7 water, first with a "home kit" and recently at a lab. The aquarium home kit using drops had a CaCo3 in the 53ppm range, lab results were 35.8ppm CaCo3. pH with my handheld meter was 6.0 and 6.31pH at the lab. I ran out of sample and was unable to recheck the CaCo3 results; pH was run after a fresh two point calibration.
Room for improvement, but not out range either; good to see the recommended specifications posted again.

Looks good. Was that a GH (total hardness) or a KH (carbonate, alkalinity) measurement?hankua wrote:The aquarium home kit using drops had a CaCo3 in the 53ppm range, lab results were 35.8ppm CaCo3.

The aquarium kit test was KH, CaCo3 lab test was on a Orion benchtop meter.

hey just saying hi here! I live in Jacksonville as well and the bianca will hopefully arrive next month ( the first shipment got damaged and was sent back )
I've been using ispring 7 stage for a couple of years. my TDS meter measures around 300-350 ppm for the city water and 40 ppm for the re-mineralized RO water. will try a home test kit to determine the KH values....

You should first verify the TDS of the permeate water from the membrane before it hits the post filters. Next check the TDS after the post filter. If you are using the iSpring RO with a remin filter, and your post RO TDS is 40ppm, there's no need to get a home test kit. All of the 40ppm of Total Dissolved Solids will have likely come from that post filter. So, whatever the composition of that post filter is will be the TDS. You can probably contact iSpring for the filter composition, if the information isn't stated on the filter body.

yup the TDS post-RO pre-alkaline filter was about 6-7 ppm. They didn't state which minerals other than calcite and corosex. I'm concerning if the water is alkaline enough for espresso and will test it to find out....

I think the current iSpring FA-15 is as you say calcite and Corosex, plus some red mineral balls that I suspect add very little minerals.
Calcite will add calcium bicarbonate. And Corosex, which is magnesium oxide, will add magnesium bicarbonate when dissolved in water. They both increase the hardness and the alkalinity by an equivalent amount. You can measure that with a KH or GH kit geared for measuring low values.
You can also get away with using the ubiquitous cheap conductivity "TDS meter", - this is a case where those cheap ones calibrated to the NaCl factor of 0.5 happen to come out in the right ballpark** -- The increase in TDS reading (before and after the remin filter) at that calibration factor will be approximately the same as your increase in CaCO3 equivalent for both hardness and alkalinity. Take the reading at a water temp of 25C.
** There are other cases, for example San Francisco city water has a TDS ppm that is about half the conductivity in uS/cm.
I base my factor for remin carbonates on calculations from the Aquion site: For example a water with 40 mg/L CaCO3 equivalent hardness and alkalinity from magnesium oxide and calcium carbonate additions will have a conductivity of 76.5 uS/cm and would read about 38 ppm on a TDS meter calibrated to factor of 0.5:
