just became a member so i'm a little behind on all this! in fact this is the first time joining a club. I will try and start a tank journal sometime this week so you will see. But in any case, I have a 72 Bow that i am trying the Zeovit method on. I'm on my 5th month with fair results. Most threads i read say that between 6-10 months is when you will start seeing results. I am running the Giesemann Infiniti for lighting and a jbj arctica to control temp. have an old CaRx but plan on yanking it to try the Balling Method as soon as i find a deal on the GHL Profilux standalone doser.
