Ca reactor

[twomenandatank]

i have a 120 and was wondering how hard is it to put a ca. reactor in and are they real expensive?

it's not hard you just need to dial it correct and to find the correct adjustment and forget (once in a while you will need to dial it again)

i have on my 120 gallon the GEO 6/12 and it's work perfect if you want very good reactor i suggest to buy the GEO .
