All of the other species tested gave similar results (plus or minus a factor of two). Harvesting 10 grams (dry weight) of this macroalgae from an aquarium would be the equivalent of reducing the nitrate content by 2.5 grams, or 10 ppm in a 67-gallon aquarium. All of the other species tested gave similar results (plus or minus a factor of two).

“blue baby” syndrome. When the nitrate-contaminating source is removed, the effects are reversible.
HI9829-14/15 is for premium quality 10 ppm and 100 ppm (mg/L) Nitrate (as N) standard for calibration. These standards are used to calibrate the HI7609829-12 Nitrate ISE. Each sachet has the lot number and expiration date stamped on it. The sachet is made of light block and air-tight foil ensuring freshness each time one is used.

Concentrations above 4 ppm may indicate contamination. The problem is, now I have some ammonia back in the tank. There is not too much of it, I would say somewhere between 0.25 ppm and 0.50 ppm, but that is the absolute highest it could be but it is definitely still there. The nitrite readings are still completely 0. Is my tank cycled, and is there anything I can do to try and get rid of the ammonia?

A nitrate reading of 10 ppm is OK for fish only. Corals will not last with it that high. Small WC's will not do much to lower the nitrate. You must do larger changes to see a difference. You may also what to get your water checked by a LFS. I recently had a test kit give me false nitrate reading. _____
