I bought the mr cal reactor for $100 with media thought I got a good deal just needed a pump which I found used for $25 its a blue line will be picking up this weekend !
I have a ph controller just need to buy new probe but will not be using a solenoid valve this time as I had one on my last cal reactor and it was a hassel and burnt out!
What else do I need too run this
Do I need a feed pump if so what kind I did leave some Ts in my return line I would prefer to use 1 of them so I'm not adding another pump !!
So basically this thing is kinda confusing can anyone who owns one post some pics with advice on how to set up?
