So it's 2010 now. Who still uses a calcium reactor and who's all on 2-part dosing?

Never had dosers, I've always been happy with a calcium reactor. I used to hate manually adjusting the bubble count/effluent rate, but now that I have a controller, the ph in my calcium reactor is always between 6.6 - 6.7 with the controller controlling the amount of C02 going in. The best thing that I have done is "T" off of my return line to feed the reactor. I used to gravity siphon feed but it wasn't as consistent. Now it is truly a set and forget item. I couldn't imagine the regular labour of 2 part dosing. I am so lazy that I cringe at changing my carbon once a month even though it only takes 10 minutes. I cringe at changing my zeo rocks once every 2 months....

So I guess my vote is Calcium reactor all the way!
