To answer your question about alkalinity I just tested it today and got 40 ppm CaCO3. I heard that to increase it you can use ag lime but over 50 ppm better to with calcium sulfate (gypsum). Is that true with you guys? Also, is pelletized lime better than pulverized? Will pelletized react in enough time?
I know I have a puny pond. I will have to watch the population. Hey, thats my pond. I wish I had bigger but around here one is lucky to have any pond, its not like I live in a rural area.
