Did get my TDS meter today and tested my regular drinking water and it says 131-139 the 3 times I checked and
thats the 3 best in the list it says "Hard water" Just little curious how is your drinking water in like USA and such ?

I live in the UK and my water's medium. (what's a TDS lol! )

total dissolved solids

mines 158-159

Portales, New Mexico, US
Flytrap Store Greenhouse South

TDS (Total Dissolved Solids) of several water sources

• Tapwater -- 227 (enough to kill a Venus Flytrap in a few weeks)
• Reverse Osmosis under sink unit -- 26
• Collected Rainwater -- 6 (includes small amount of soluble material from rooftop and sides of tank)

So your rainwater is better than RO unite then ? I did get my Osmosis system today (: but havnt figured out all tubes and all yet :p

Well, collected rainwater is almost as pure as artificially distilled water. Reverse osmosis is very effective at removing almost all dissolved solids and the difference between it and distilled or rain water is negligible as far as carnivorous plants are concerned. Reverse osmosis water is fine and very good for the plants.

Just for comparison, even the TDS of pure sphagnum peat moss alone, after distilled water has been added to it to the saturation point and allowed to sit for 12-16 hours, can be 65 or more, so don't worry too much about the small amount of residual TDS in reverse osmosis water.

Steve,

Just wondering what kinda R.O unit do you have?

Hi Allen, it's just one I bought at a nearby Sam's Club a few years ago. It's much like the under-sink reverse osmosis systems at the following websites:

Hah, I like this Steve. I'm going to copy it!

TDS (Total Dissolved Solids) of several water sources

• Tapwater -- 54 (low enough to use directly from the tap on most CPs if allowing the water to run out the bottom of the pot)
• Reverse Osmosis under sink unit -- 1 (almost as good as distilled water!)
• Collected Rainwater -- 11 (includes small amount of soluble material from rooftop)

Hi again I have now tested and installed my RO System and I am so happy over it it have now been running for 4 hours and after 4 hours I tested with TDS and it says 0 or 1 so its 100% perfect u can say
I am very pleased with it then (: and I use this system http://www.waterfilters.net/Water-Gener ... 29083.html

where did you buy it at?

That's great, Xeno. My reverse-osmosis TDS reading (26) might simply be from an RO membrane that is older and might need to be replaced soon. It's great that yours is giving you an extremely effective TDS reading of only 1, lower than most collected rain water!

Your plants will love you for your new reverse-osmosis unit's water.

I to will love it or already do :p will also help reduce some algae etc for me
