Nitrates??

This might be a dumb question and something that isn't computing with me, but how do you keep your nitrAtes up in your tank? I don't mean above 30 but I have a big fat 0 in my tank every time I test. I always thought it was good to have at least a 10ppm reading with plants. My mind has been shot lately because of working 11 hours a day 6 days a week for the last few weeks. I know my plants could be doing better with the amount of light and ferts. So is it my nitrAtes that are keeping them from being their best or should I try upping my ferts? I was also thinking more root tabs too.

Specs on my tank listed below in my journal.

If I'm asking the most simple of questions and just not getting it smack me around a bit, I might wake up.
Thanks in advance to my newbie question.

What exactly are you dosing? You definitely don't want your nitrate to be at zero, but that is true for any of the ferts, so yes, up your nitrate dosage. Also, very important, If you do not shake the number 2 bottle of the nitrate test kit vigorously for 1 minute, like the instructions say, you will get a 0 ppm reading no matter what is in the tank.

Standard 10 Gallon (20 x12x12).
Low tech, Sand substrate.
Eheim 2211, and Aqueon Quietflow 10.
Finnex Stingray LED, 20" above substrate
2 Anubias Nana Petite, Christmas moss.

If you are doing full on EI then you do have nitrates. That second solution added to the tube must be shaken well and the test tube shaken well for the test to work. Or perhaps the test itself doesn't work any longer. You could make a test for it with a drop or couple grains of your EI stuff in the test tube to see if you get any reaction at all.

Do try more or less of one or other of the fertilizers. Just keep track of what you are doing to see if you like what is going on. My plants seem to like a little more nitrate, lots more phosphate and the same amount of micros compared to the amounts suggested in the sticky for instance.

Thanks for the help. I don't know the exacts, I have everything written down at home so I don't forget what to dose when. I must've skimmed over that part of the instructions. I follow pictures better...

I know how to keep nitrates up, dump a whole can of fish food in there and see it soar.

Kidding aside, if yours are reading 0, I'm sure it's probably 0-10, so very low which is good. You obviously know what you're doing if you have discus so I wouldn't change a thing of what you're doing. Water changes and good plants/filtration/non-overfeeding will lead to low nitrates which is what you have and is what people strive for. Personally, once the tank is all cycled I pretty much stop testing or test only if somethings odd.

Actually, in a high light co2 injected aquarium, it is quite possible for nutrient to bottom out. 0 nitrates in a planted tank can cause BGA to appear and flourish. Nutrient deficiencies can also cause unhealthy plants which can lead to other, worse algae problems.

I have had that happen but it was long before I started dosing EI. A tank dosed the suggested amounts won't bottom out.
