I've been thinking about starting a shrimp tank, but I've been wanting to use tap water with conditioners instead of going out and buying RO water. Since my tap water is around 150 TDS which is not that high for a shrimp tank. I've tried testing how the water would be by adding water and water conditioners into a cup and seeing the TDS. It instantly went to 2000+ TDS. I'm currently using florin volcanic rio escuro FX as my substrate, which supposedly should help with TDS and GH, but I just want to confirm it. Is there anyway to lower TDS? Does letting the water go through the nitrogen cycle help with the current TDS?
