Big jake glad to hear it. I somehow did not see your ealrier post, but I miss them b/c I some times do not check this site for a week or so.

ANyway two things one in first post you said Zsd went down to 18 inches after fert. Well you got a bloom but it was brown phytoplankton species. Otherwise the Zsd would still be 24 inches.
2nd I think since you got a good green bloom this time you are unique and the limiting nutrient in your case is not phosphorus( middle #) but nitrogen (first #) so by adding more nitrogen in the 20-20-5 you were able to form the green bloom. IN your case a higher first # helps you out but for others it is opposite. Glad to hear the good news and just my theory on what has happened.
