I've been battling this for awhile I have what I would call based on other peoples high p04 test extreamly through the roof high p04. I tested .84 about a month or so ago did a large water change and brought it down to like .6 I've been running gfo and now I'm running I believe phosban not sure it's a white ball my lfs told me it would probably help more then gfo. I know he said its aluminum so not to let it tumble. However for about the past 2 weeks I have gotten my p04 to .5 but it wont drop anymore then that. I have changed media on average every 10days due to how high my levels were I figured the media locking up really quickly. I believe that my rocks are the most likely cause but wasnt sure if there was anything else I can do to try to get it to a more acceptable level. O and my nitrates are 0 based on api test and p04 was done with a hanna checker thanks for any help in advance.
