DI should be producing 0 tds. That number you have is high for simply an RO unit. A good membrane has a rejection of 98% or so.
More info needed....such as:
What is your incoming TDS?
What's your water pressure?
Who's unit and how many stages?
How old are the other filters?
Do you have a pressure guage on the RO unit?

I got my water from the grocery store and I never test the water when got it from the store until today bcuz some of my sps are not looking great..(the tds kit I just got it yesterday) well thank you guys..!!..good thing that i got the tds kit..hehe
Are you referring to a handheld TDS meter?
How are you testing and in what? Was the container the RO/DI is in used for something else previously like water changes, if so it could contain salt residue which may or may not be bad but will skew the readings.
Go to your LFS or grocery and test their water straight out of the machine or their storage container so you have a good idea what the water really is and not the containers. If it is still high TDS then find a different source or buy your own RO/DI system for around $140.

Those grocery store filtered water dispensers are usually poorly maintained. In my experience the filters are either so old or not even being used and you're getting tap water pretty much. I would either start using rodi made at home or distilled off the shelf in jugs.

I lived in a rental apartment for 8 years with my last reef tank. I set up a temporary RoDI station in the bathroom. I installed it under the bathroom sink and just ran it with a tap attachment.
Much better than depending on grocery store for RO water. You can keep a closer eye on the TDS and just change the media as needed.

Test the water from the source, not the bucket. The bucket probably contains salt residue or if it is new plastic mold compounds and oils. Rinse the bucket well with a vinegar solution and use it only for RO/DI water, use a separate bucket for water changes and cleaning pumps and powerheads.
You need to know what the treated TDS is and you will not get that testing from the container, draw a sample directly from the source using the cap on the TDS meter. Also make sure to triple rinse the meter and cap with RO/DI before capping and and putting it away so it stays clean and accurate.
