Has anyone noticed a correlation between the use of RowaPhos and an outbreak of HA? I had been using BRS's HC GFO and never had a problem with HA. Then I bought into a group buy for RowaPhos, due to the great price. Since then I've been having a bit of a problem with a short brownish green HA all over my sand bed and most of the rock. All my params are excellent. The only thing that corresponds with the HA start is the RowaPhos. So, again my question, as this happened to anyone else?
Thanks for any input.
