If you ate changing out 30% twice a week, the nitrates ought to be significantly lower already. If I were concerned with keeping my shrimp berried and carrying those eggs to term, I would stop with the ei dosing , especially the micros and nitrogen so diminish the need for water change. If the shrimp aren't a priority, at the very lease see to the source of the nitrate elevation. Perhaps the soil is leeching it?
I guess it's posible the soil is leeching. I originally planted the tank 8/21/12 and filled it 11/22/12. I tested the water for the first 5 weeks for amonia and nitrates and it had always tested 0 ppm. I attached a few pics of my most recent nitrate test. The red color looks high to me. What do you guys think?
Also, I have about 15 fish in this tank as well. 6 of them are chili rasboras. They are small. I know they are a contributing factor to some nitrates as well. They are fed once a day very sparingly.
