TDS in planted aquariums

Hi all,

Just shifting focus from shrimp to my planted tanks and noticed that the TDS read nearly 400 ppm in one of my planted tanks. Of course this is prompting for a water change. The TDS out of of the house tap is 30-35ppm.

Wanted to see where most of your planted tanks with fish run in respect to TDS. My tanks are overstocked with plants and fish and i typically do water changes weekly along with pps pro dosing and GH boosting.

The TDS in my high tech planted 75 is around 250. The TDS in my planted 120 Discus is 160. The TDS in my 55 gal planted CRS tank is now around 135. Because I have a 300+ TDS tap water, I use 100% remineralized RO/DI so I can dial in the TDS and parameters I need for my plants, Discus and CRS.

buildup of salts and minerals mainly when you dosing ferts, the same reason to do 50% water change because of this buildup when people use EI.
