hey guys, quick question.... we will be having the external pump to pump out saltwater when needed and to circulate the salt water in the jug to help with the mixing. Is it necessary to add an air stone in their as well, I was thinking if there is enough surface tension it wouldn't be needed and lastly in the 30 gallon reservoir with the ambient temp this time of year being pretty cold in the garage I was thinking of about a 300 watt heater... overkill? not enough? thoughts?
and any other mixing expertise will be greatly welcomed haha, ive never mixed my own before. I am leaing towards brightwell salt mix
