Hi. In April of this year we had our liner replaced in our in-ground pool. Water has been great up until last 2 weeks. Chemicals are balanced and readings are listed below, I use the Taylor K-2005 kit. I've been finding small patches of algae, not a lot but enough to know it's there and needs eliminated. I find it in corners or along the wall, and around the frame of the steps. I brush it all away and then shock it. Usually find it again 3-4 days later in corners and such. I had a little trouble in the beginning getting chlorine levels balanced, and aboout 3+ weeks ago I was having trouble getting alkalinity normal, it was a bit high at 150 but now is normal level. Hoping someone can offer suggestions on what I should do, and why algae is starting to grow. I always thought if the chemicals were balanced then no worries of algae. Pool details: 25,000 gallon vinyl liner, 2 skimmers, full sun--no shade. Not sure if any of this is needed but for chemicals I use: Arm & Hammor Baking Soda from Sam's Club (for pH add), Aqua Chem Chlorinating granules from Lowes which has Trichlor-s-triazinetrione: 71.8%, Boron sodium oxide: 8%, Other Ingrediets: 20.2%, Available Chlorine: 65%), and Aqua Chem Chlorine 3" tabs for in-line chlorinator. Thank you so much for any help that is provided. Anna
