No, I did run ultralith for awhile though and the dosing regime is hugely important to make it work. I'm away from home during the week and only home on weekends. I was having my boyfriend dose the tank when I wasn't there. However, he had extended periods where he was away for 2 or 3 weeks at a time during the time I was running the ultralith system and I could see that it just wasn't really "kicking in" not in the way that Wendells display tank at OA did. I attribute this to not being able to dose the tank properly and on a regular basis.
As well, I have a fair bit of detritus build up on the bottom of my tank (barebottom) which is not only unsightly but who knows whats brewin in there. So I was doing 10% weekly waterchanges at the time to siphon it all out. I'm not sure what they actually prescribe but I would imagine its much less than that. They almost reccommend that you run a sort of "closed" system and water changes are only for trace element replenishment like someone mentioned earlier.
I'm going to try it again if I ever move back home on a more permanent basis as I do believe it works (see Jason McK's zeovit tank photos for clear evidence, its amazing). I just need to follow the rules a little more closely
