I know we periodically test our tank water with hydrometers or refractometers, but how about our source water or our purified water?

I’d like to do an informal study on the total dissolved solids (TDS) of our water sources and our purified RO/DI water, while also testing our TDS meters.

Everyone can easily participate in this study.

Objective:
1) To learn how varied our freshwater TDS levels are in North Georgia,
2) To learn the TDS level of our purified water whether by Reverse Osmosis (RO) or by Reverse Osmosis/Deionization (RO/DI) and
3) How well do our TDS meters compare to the others used in the club.

Three simple things you need to do to participate:
1. Please collect 12 to 16 ounces of your:
A) tap water as well as
B) RO or RO/DI water.

2. Please label both of your containers with masking tape and write
A) your Last Name and Alias,
B) the town and county where this water was taken
C) the source of your fresh water supply (e.g., Smyrna well water, Cobb County municipal water, etc.) and
D) the type of water in the container (i.e., tap, RO, or RO/DI).

Step 3. (Optional) Please bring your TDS meter (with your name written on it in indelible ink).

At the meeting, we will organize the testing of all of the water samples and collect the data.

The results should be interesting and will be published here.

Sounds like a very interesting idea.

Great idea! This should be very interesting. I'll bring my TDS meter. Any idea where the meeting will be held at?

Where is a good place to buy a TDS meter?

You can get them from one of our sponsors such as The Filter Guys. Here's their Web site on TDS meters(http://www.thefilterguys.biz/tds_meters.htm ), but some of our local sponsors may have them too.

When buying from one of our sponsors, please thank them for being an ARC Sponsor!

Thanks!

sam at aquabuys has them too, there cheap, i think his is like 20 bucks..

Our next meeting will be inside I-285 off of I-75 on Sept 12th. Please click http://www.atlantareefclub.org/forums/showthread.php?t=1081 for more details about directions and the presentation being given.

Thanks for asking,

Bob

I hope everyone will bring (tap and RO) water samples so that we can see what the water quality is like around metro Atlanta before we purify it as well as what we're adding to our aquariums.

Please post here if you plan on bringing water or a TDS meter or both.

Thanks in advance!

Bob

i will bring tap and ro water but am short the tds meter, mine craped out. this is my first meeting so im looking forward to meeting everyone. dorian

Thanks Dorian!

I may look into asking about having a PowerBuy on TDS Meters as Pilz suggested, but it won't be for next week's meeting.

Bob

We should try that tap/ro water testing again.

I am sure more people will join in now that they knew we are doing it.
