Almost a year ago, we purchased this In-Line Dual TDS Monitor to monitor the performance of our new RO system: (http://steepster.com/teas/teaware/37798-abundant-flow-water-6-stage-alkaline-zoi-zeta-reverse-osmosis-system). This meter monitors the TDS both before and after the RO system, which is important for brewing tea:

“Water with 50 – 150 ppm total dissolved solids (TDS) or 1 to 3 grains hardness provides the best results, according to the Tea Association of the USA." http://www.teaandcoffee.net/0609/tea.htm

Sensor Locations:
• For monitoring the TDS level of the untreated water, the “TDS In” sensor should be installed after all the pre-filters and just before the RO membrane.
• For monitoring the performance of the RO membrane, the “TDS Out” sensor should be immediately after the RO membrane.

These two sensor locations provide the two TDS levels necessary to calculate “RO Percentage Rejection” – the parameter that determines when to replace the RO membrane (about every 3 years). See the bottom ½ of this page: http://www.tdsmeter.com/what-is?id=0003

Notes:
1. If the water in your area requires an RO system and you wish to use this water for brewing tea, a re-mineralization filter such as this (http://steepster.com/teas/teaware/39532-puregen-aptera-alkamag-water-filter) is highly recommended.
2. An additional fitting should be added to RO System that has a re-mineralization filter so the output sensor can be located either after the RO membrane for maintenance purposes, or after the re-mineralization filter to monitor the TDS of water used for brewing tea.

After using this In-Line Dual TDS Monitor for nearly a year, I’ve found it to be a simple and reliable device that provides consistent TDS data for monitoring the performance of both RO systems and re-mineralization filters. Highly recommended.

My wife & I are passionate about teas that are full-bodied, rich, thick & creamy smooth. I joined Steepster to explore Multiple Infusion Teas (MITs). Currently, our focus is on ripe pu-erh teas.

We especially enjoy teas with a mildly-sweet rich chocolate flavor profile as opposed to bittersweet cocoa.

Cost-effective organic teas or teas that meet the EU Food Safety Commission Pesticide Maximum Residue Limit EUROFINS are greatly appreciated. Many people drink tea for the anti-oxidant health benefits. So why would health conscious tea lovers drink tea that contains pesticide residues?

Complete steeping instructions on the bag are greatly appreciated:
tsp. (g) / oz. / temp. / rinse? / min. for both Western & Gongfu brewing.

Our recent orders have been from: Tao Tea Leaf, Whispering Pines, Yezi, TeaVivre, What-Cha, Mandala, Zen Tea Life, Verdant, Berylleb (ebay), Grandness (Aliexpress), King Tea, Yunnan Sourcing. Kudos to them as they have all been extremely helpful.

Our cupboard doesn’t include the many greatly appreciated samples generously provided by Steepsters’s favorite tea suppliers and by several very kind Steepster members.

Current Gogng Fu Brewing Method:
10-15g / 6 oz / 205° / 60s preheat / 60s warm leaves / 5s rinse / 20 min rest / 5s / 5 / 5 / 5 / 15 / 30 / 60 /120. Every two steeps combined in a sharing pitcher.
