Isn't Tomball down by Houston? If so, or even if it isnt for that matter, I would contact kelley Dufffie by email. I emailed him and he gave me a line by line, step by step process which cleared up my algae problem in about 3 days. He will ask you the size of your pond and your goals and then recommend the proper chemicals from there. He seems like a very straight up guy, does this kind of stuff for a living, and most of all, he doesnt push his companies products on you. He gives specific product names and isn't really concerned where you purchase them. Most of these guys in here are all professionals, but Kelley is in Houston and is probably familiar with you situation
