Chem concentration question
 

Does any body know the concentration of the BRS Recipe 1 mixtures off the top of their head, & do you ever mix them higher than suggested? The reason I'm asking is that the amount I'm dosing daily is going up weekly by 12-15ml because of consumption & I think it'll start to affect the ATO due to the amounts being added.

you should have no problem with having your mixture more concentrated.
if you are not sure the concentration level will be reached by having not able to dissolve the chemicals in the given amount of RO water.
