Keeping Nitrate Levels Down

Do regular maintenance on your filter media. If not maintained, filter media may contribute to elevated nitrate levels in your tank.

I agree! :)

You do have a lot of fish, but at those sizes in that size tank, you really shouldn't be getting high levels like that, unless something is wrong.
 
Well first of all, I'm not sure what would produce additional nitrates in your filter media. I always though your filter turned ammonia into nitrites then into nitrates. But maybe I'll learn something here.:popcorn:


Second, what are you calling high nitrates? over 20ppm, over 40ppm, over 60ppm?

I assume your ammonia and nitrite levels are zero.
 
I'm using an API nitrate test kit. basicly I get a 80ppm everytime I test that tank. My other two tanks come out find and I do W/C on them every week.Could it be the sand. I stir it up before W/c to let any trap gases out. The clown loaches and catfish keep the sand clean their is barely any waste laying around.
 
How old is the test kit? Could be old and giving you wrong test results. That's one possibility anyhow.
 
I know that there are nitrate absorbing resins you can get and add to your filtration system. I've never used them but it might work to get them down to a better level.
 
how often and how much water do you change in your 100gallon? If your tap water is a zero(prob 5ppm) and ya did a 75% W/C that will drop your nitrates down to around 20ppm. Then ya need to monitor daily and when it hits 40ppm do a 50% change to get back to 20ppm. once you get the rate of how quickly your nitrates rise, you can tailor your W/Cs and even work on getting the levels down to 10ppm.
