Best RODI replacement filters?

I am currently using a 5 stage RO/DI filter with the chloramine carbon in stage 2. The TDS meter attached to the RO/DI is showing 0 TDS but my TDS pen is showing 130 TDS in a 5 gallon bucket. Not sure which to believe but I am starting to have another bout with gha and dont want to go through that ordeal again. The DI is the color changing and only about 1/4 has changed and the filters still look clean. I am guessing I just need to get better replacement filters to catch the other 130. Is there a better brand? I have been using the Bulk Reef Supply chloramine 5 stage replacment pack. thanks

Are you sure you aren't getting salt or something else out of the 5g bucket? Have you tried putting output water into a smaller, clean container to measure with your pen?

I just found my error. I have been trying to set up a quick water change setup but forgot to let the RO/DI run for a minute. In the first minute, the TDS started at 260 before the RO/DI then dropped to 130 after the first 3 stages. Once I let it run for a minute then tested, the water showed 14 TDS before the DI chamber and 0 after. I hate when I get in a hurry and just cause more work. Thanks Charlie for the reply. Dang operator error!
