I should have explained that more thoroughly.
DI resin absorbs ions (charged particles dissolved in water) out of water as water passes through the resin. Resin doesn't pick certain ions, like nitrate for example, but it absorbs all ions. The resin continues to do this until it is full/exhausted.
Your saltwater is about 35 parts per thousand salinity. This means that about 3.5% of your tank's water is salt (ions).
If you pumped your tank's water through DI resin, the resin would absorb ions out of the water. But the resin would become full/exhausted almost immediately, like way before you saw any reduction in nitrates.
Chaeto works okay, but it won't work miracles. There are other things you can do:
Water changes are the most efficient, but are expensive on large systems.
Carbon dosing. Do you have a good skimmer?
Remote deep sand bed.
Feed less.
Edit: what is your nitrate reading?

thank you
nitrates are somewhere between 20-30ppm API test kit
after I slept on what u first said
I now understand what u are saying
read up more on it
yep water changes work best but 100gal at a time
my city water bill for 3 months was $749 between the water changes
the pool and the lawn sprinkler YIKES
bio pellets no go
maybe I will go back to Vodka dosing
my tap water seems to be part of my problem 15ppm
so I been trying to reduce it first coming in
which I did not ck till after the nitrates kept coming back after my water changes
I have a old sand bed
tanks been up for over 20years
things still look good
I have 20 fish
big red bubble tip
2 red dragon coral doing great
two big red plants
two strawberry short cakes
20 mushrooms
10 ric s
purple plate
leathers
18 flower nims
reverse superman
10 other SPS
thank you for replying to my questions
it helps to get a pros help

Are you not using a Ro/DI to filter your tap water?
Also 20ppm is totally fine for nitrate. I just watched a BRS video about the WWC display tank and they said their nitrate is at 20ppm.
Also, you don’t need to do 100 gallon water changes on a 250 gallon tank. 50 gallons per change should help.

If you don't have major algae issues, and corals are doing fine, then I wouldn't worry about it.
It might be worth getting a second opinion on the nitrate test. Take it to a lfs.

no algae issues phosphates are low from GFO
use the same nitrate test kit to ck other reef tanks much lower then mine
the also have lighter loads
just was hoping for a better way to reduce nitrates
did not know nitrates had to be low to keep them low with BIO pellets
not what I been looking for and explains why my bio pellets are not lowering my
nitrates ...useless and a waste of my money

When I had my 4' Gymnothorax Undulatus (Undulated moray) In a 150DT/50g sump by himself Nitrates were always a big issue. Because he would eat 2-3- hand sized fillets a week he also produced a significant amount of waste. Even with a 50% water change the nitrate readings were too high for any normal test kit to give me a number. After doing battle with algae and cyanobacteria for years, I stumbled across the idea of a remote DSB. To be big enough to actually stand a chance of working, I used an old 120g tank with ~6-8" of sugar fine sand. Within a couple months, there was a noticeable reduction in the algae/cyano problem. After a couple more months, nitrates had been reduced to a point where they were actually testable, and within 6 months were essentially gone from the system.
IMHO, the reason many people have no success with the use of a DSB is that whatever they have is just too small to really stand a chance of helping.
Go big or stay home!
