i have a tank set up with approximately 40 pounds of aragonite crushed coral and roughly 40 pounds of rock and was wondering what kinds of plants i should use to lower my nitrate levels. Maybe my test kit is defective but i do weekly water changes of at least 10 percent. Ammo nitrites are always 0 ph around 8.2 and a KH of 6. Water temp is 80-82 nitrate reading of about 20-30 ppm i test the water out of the tap and it tests 0 nitrates but after just a few minutes after a water change its back around 20-30 ppm it never gets any higher than that but am concerned about the long term affects of it on my fish

how big is your tank? my water tests at any given moment 0-0.25 ammo 0 nitrites between 8 and 8.2 ph and 6 kh i do a minimum of a 10% change a week and treat the water with prime and jungle aquarium salt 2 drops per gallon prime and i use a little bit less of the salt than recommended i have well water so it tests pretty good all 0's ammo nitrites and nitrates but 6 ish ph

I'd be much more concerned of the presence of any ammonia (even 0.25ppm) before I became concerned about 20-30ppm nitrates.

Wisteria, Najas Grass, etc. etc. any fast growing stem plant are great for nitrates - if you have decent light and fish that won't destroy the plants.

i've been told that prime will give a false positive on ammo it breaks it down into a non toxic form but it shows up on a test the tank has been set up for about 4 months now
