There needs to be a specific Reef related math Forum on this site for us dummies LolThis has been done with other checkers on reef2reef and the colorimeter should work if you do this and don’t forget to multiply by your dilution factor.
I bought the PPb Hanna phosphate checker and was kinda stumped. Thank god for the chart online.
I struggle with stuff like figure out 2 part dosing and stuff.
Sometimes it’s the rules like, “ you can’t change this parameter more than xxx / day”
It’s just gets difficult for those of us that are mathematically challenged.
