How long did it take before you started to notice no3 and po4 levels drop.

have you increase dosage yet? I started at 2.5ml and increased to 5.0ml after the first week. Of course I got like over 200gallons but I started having steady decline when I increased the dosage

GO SLOW it will pay off in the long run. It took me 3 weeks to find the level suitable for my tank , nitrates have been at zero for 3 years now

4 weeks for me to see a drop in P04 and N03, 75 gallons of total water. I had the urge to up my dosage, but fought the urges and stayed on schedule. I'm glad I stuck to the regimen though. After 8 weeks my P04 is at 0 and No3 are at 5ppm.
