I have NO3 problem in my CRS tank. It goes to 30mg/l :shocked:
I will lower feeding, but can help something special?
How work deferent "ammonia removers"? or Zeolith as filter media?

Lower feeding is OK, also more or more often water changing.
I would check the parameters of the tapwater first!
(I have about 40 mg/l)
Sorry, no experience with Zeolith.

First, let me confess that I am new to shrimp, but I am not new to keeping fish and other aquatic species.

I feel that water changes are the best way to remove NO3 on a regular basis from all aquariums.

It is not a good idea to rely on chemicals or other products to remove unwanted toxins from the water because it is difficult to know when these products stop working.

Even if you do use one of these products, you should test your water regularly to ensure that it is safe for your shrimp.

Plants do the best job of removing nitrogen waste naturally.

Get some red root floaters and/or duckweed.
this will lower your nitrates and keep them in check.
I keep them in my shrimp tanks and they do wonders for me.
Also help with keeping other nutrients in check.

Cheers,

Good point. I have swimming plants in every tank so I was not thinking of it.
Very good nitrat eaters are Najas and Pistia stratiotes.

Try putting in some plants and Potassium as well, the potassium will help the plants suck up the NO3, otherwise if you're lacking in potassium, then the nitrate sucking ability of the plants will be limited as well.

would potassium cause any harms to shrimp?

Potassium is usually represented as the letter K in the periodic table. Possibly "Draslík" for you?

Usually dosed in planted tanks with NO3 as KNO3. Sometimes added as K2SO4 so as to not add more NO3.

You can dose the tank with KCL - still a lot of K and no sulfur nor nitrate.
