The trick is to get the alkalinity as high as possible, I really like to have 40 as a minimum. Fertilize early in the year before the plants start growing so the phytoplankton can utilize the fertilizer and less goes to feeding the plants. Toss some TGC in there, but remember that the plants are providing cover for the fish, without the cover you have to add more cover to make up for the plants not being there. I don't know how much fertilizer the TGC will provide since they are turning the nutrients from the plants into fish flesh too.

If the alkalinity is low, get it up before adding fertilizer or you might be trading one problem for another.
