Yea I use phosguard, It seems to work fairly well. I will leave mine in place for 7 days, then recheck levels and replace if necessary, directions say 4 days.
How much did you pay for what size container?

I don't remember what size it was. I paid 28 bucks for the container and the bag to put it in. I did not buy the largest size container though if that helps.
