Nitrate Issue. Where the heck is it coming from?
I recently cycled a planted tank. Shows 0 for nitrite and ammonia. I also packed it with quite a few stemmed plants including a bunch of water sprite.
However, I'm having nitrate problems. That's my biggest issue. I did a 70% total water change yesturday and it went from 20 ppm to 10 ppm. But this is similiar to my shrimp tank. No matter how many water changes I do, it doesn't seem to lower the nitrate readings much or the nitrate readings keep saying 10 ppm.
I need it to get to 5-10 ppm for my crays. I do have one crayfish tank that is at 0 nitrates and my test kit shows that.
I don't know where the nitrate is coming from in my newly cycled tank and from my shrimp tank.
I completely changed the substrate in my shrimp tank and changed water constantly every few days and still 10 ppm. Where the heck is it coming from?
Aren't the plants suppose to suck up nitrates? I don't get why my crayfish tank has 0 nitrates and my shrimp tank has 10 even though they both have similiar plant mass in both....
I don't know where the nitrates coming from and its rather frustrating. Am I suppose to do a lot more water changes just to get rid of the nitrates?
