No sure what size your system is, but I wouldn't change more water than 30% at one time. If you need to change more, than use smaller multiple water changes to be on the safe side & give any heavy metal build-up time to allow the organics to tie up the heavy metals into a safer form.

Hi Cliff
Yes, I believe it's safe to say that AF works.
I shouldn't have let the HA get so bad to where I now have to dose for so long
At least I bought the largest bottle
I have a 135g and sump so with rock displacement, I figure it's about 145g total. I took the rock out and scrubbed as much of the dead and living HA off the rock as I could. I removed the sandbed also. The WC was about 20%...30g. I will test later today and depending on the results, I may do 2 more 20% WC's this week. Thanks for the guidance on smaller WC's
