When I did it I did one small cap, polar ice cap, every 2 days in a 150gal+50sump. That was too fast of a start. Its like a anti nitrate bomb, so shocks the system. after about a month I got up to a cap a day, but that was even a little heavy, so once everything was balanced I was at about half a cap a day(more like a cap every other day, I'm terrible at schedules). Every thing seemed happy, so I stopped and let my added bio balls pick up the slack. I'm thinking of starting again though, everything seemed happy.
I did this with a tfl150 of bio balls. Upgraded to the big reactor with more balls at the end. Thats why I stopped
