I am using a Vortex D-1 diatom filter with powder from a pool supply house and I must say it works great. I get GW in my soil tanks if I uproot plants. I didn't think I had any in the last week but ran the filter on it just for kicks and the powder turned green overnight. I do switch the powder out often if the tank is very cloudy that I am polishing,other than that i use the powder multiple times...
I don't recall if they make different grades of Diatom powder or not,maybe that could be the problem and if so it would be in the hands of the supplier to which grade they sell.
I have purchused some at HD in the past and ran it in a HOT filter and it worked great.
HTH Russ,Good luck with the GW.
BTW I have some crypts for you, let me know if you are coming to the next meeting,it will give me a little more time to cultivate them a little more.
