Brand is called Kootenay filter,company based out of Canada with an ac infinity fan. I'm pretty much running a perpetual grow,so there isn't much time where the plants aren't stinking,thats why its been running almost continuously.
I was confused I thought you where saying that you been running you filter for a year and a half and now going to run a cdlc to test the filter. Which i was thinking it was just running air that dont have that sweet weed stank for the year and a half. Didnt make sense to me but now it does. A year and a half for your filter is not bad I never ran one that long yet but I herd they normally last up to a year.
