GH measures the hardness of the water, whereas TDS measures the total dissolved solids in the water. GH measurement gives you the approximate content of Calcium & Magnesium. While TDS gives you the approximate content of Calcium & Magnesium, as well as other dissolved minerals, metals, organics, etc in the water. So apart from Calcium and magnesium, what are some of these dissolved solids that the TDS meter is picking up? It will pick up minerals like Sodium, Potassium, nitrogen, phosphorous, sulphur, silicates as well as dissolved metals like Iron, Copper, Lead. It will also pick up Nitrates, and chemicals and pesticides that might be in the water, just to name a few. So as you can see, GH measurements can reflect TDS measurements if all you have is Calcium and Magnesium. But reality is that you will have more than those minerals in your tank water. So the TDS measurement will usually be higher than the GH measurement, since the TDS meter is made to detect more.

Couldn't resist in adding some more pictures of the beauties, the hardest part is selecting which pictures out of the hundreds taken are good enough to upload. What is nice to see is that even non-berried shrimp will be carrying interesting patterns. The annoying thing is having to wait for the different types to emerge out of the depths of the plants and log for photos, before the snails manage to swarm over the food.

Yes, I understand with what you say Baccus. I caught a 10th of new ones today, including some black tiger looking like. That's a thing I was wondering about: are all the different colors I find are just offspring's, or are they trully different? Here are some pics of the new critters. Sorry for the poor quality, I really need to buy a better camera, rather than the one from my phone. They are "reddish" for the moment, they will be black & white in 2 more days, after they settled in their new home and calm down. This one has more white than the others
