Thanks for reading. I am so sick of struggling in this hobby! I am trying to mix some rodi water for a water change. I recently redid my water filter setup. I added a dual cartridge for my di resin. Before this i was getting 0tds now I cant get below 2ppm. I also thought my di resin would not be using both up.at the same time? I cant do anything right in this hobby!! What am I doing wrong? Also the first 3 filters seem to be doing nothing. Water comes in at 500 tds and when it gets through the 3 filters it is right around the same. After the ro membrane it is around 9 and after di 2 tds. Sometimes when i first start making di water the tds meter will be really high and then slowly come down. Is this. Normal or are my meters junk?
Thanks for the help
