best way to remove nitrate


hellows

In my shrimp tank, i have annoyingly high nitrate levels. Unfortunately this is due to my tapwater, being 50mg/l out of the tap. This of course is good in my planttank. Not so in my shrimp tank.
What would you guys suggest? what will bring my nitrate levels down?

it's a small 40L tank, with javamoss and a few echinodorus.

Throw in a few floating plants. Fast growers will take care of it quick enough.

GREAT suggestion!

Low tech, chemical free and effective. Brilliant!

The fastest way I have found is an anaerobic bacterial nitrate filter. I have found that it works faster than plants or algae.

The cost can get high if you get all the tools you need to automate it (orp probe, orp controller or computer, and dosing pump). But it's extremely effective.

But in a well planted tank this should never be an issue....

This is a small tank, so you can use partial RO or distilled water to cut down on tap NO3. Shrimp can probably tolerate 50ppm NO3, but I agree it is not ideal for them to thrive.

try it, I bet it will take forever for the floating plants to suck up 50ppm NO3, but I might be wrong Your other plants in the tank will suffer because the light would be blocked by floating plants.

I would just get some distilled water INITIALLY, then do 20% weekly water change, which adds 10ppm NO3, hopefully that is enough to last whole week for the plants. Also add more fast growing plants in the tank.
