apex jr. and ph
I'm curious, is it really necessary to closely monitor my ph if i am 2 part dosing. Reason I ask is I would like to buy a apex jr (as it is only $240 compared to lite at twice the price) to run my 2 dosing pumps and skimmer. My lights and mp40 do not need any help so I'm thinking a jr will suffice. Thoughts kindly appreciated
