Exclamation TDS (Total Dissolved Solids) & It's importance in Shrimp Rearing

In the process of starting up our first tank together and this time it will be just CRS only tank with a few horned nerites and ottos. Since we got most of the basics down now and just waiting to fill our tank by the beginning of October, we want to go over the last bit of info we need for successful shrimp rearing and breeding : )

For the TDS, given that the digital technically could work forever, is it necessarily "maintenance free"?

Test Strips on Amazon for $12


Digital Tester on eBay for $9


Which one is better to go with?

What are the best parameters for shrimps?

How to lower TDS or increase it?

Digital, ill sell you one if you want. Never ever buy a test strip for anything unless its fresh litmus paper. Test strips are about as inaccurate as you can get

And the meter reads TDS.... the strips are measuring hardness in PPM. They are not the same thing...

am bit confused about the TDS meter, last time i tested, it was reading 250ppm on the meter and API test kit was reading 6dh, now either one is inaccurate.

They are testing different things... If you get the same results, it is coincidental.

so does that mean API results represent real GH, while TDS meter detect other things which does not really represent real GH?

Yes, tds could be "cleanliness", ro water has close to zero solids disolved in it. Water with nitrates and phosphorus has more solids dissolved.

Reconstituted ro water measured with a tds meter will yield a ppm of hardness, only because you have only the hardener dissolved into the water
