Cecil - your "old debt" experience doesn't surprise me. We encountered the same accusation - and ceased doing business with them shortly thereafter. Desperate measures for desperate times??
As for expense: at full "retail", a 14-week full-dose regimen treatment would average out at less than $25/acre per week. Definitely not cheap in my book. But, if a pond has developed a nutrient overload problem that needs correction, it may well be a worthwhile investment - at least until the situation has been corrected to a tolerable level. The alternative remedies may involve less desireable algaecide treatments, lots of manual labor or a risk of fish problems due to severe O2 fluctuations or crashes.
