After alot of research and chating , I am using this formula. There are a good amount of formula's out there but this is the most used I found and close to nopox formula ratios.
500ml vinegar + 375ml vodka and 125ml rodi water..
Along with following nopox formula directions and maintenance.
NO3 above 10ppm dose 3ml/25 gal
NO3 above 2.5ppm but less then 10ppm dose 2ml/25gal
NO3 above 1ppm but less then 2.5pmm dose 1ml/25gal
For my 300 once I get my numbers where I want it then it will be 11 ml daily for Maintenace.
If you got to red sea nopox dosing calculation page it will tell you based on your type of tank and size...
Oh it is stella time....
