How can I get control of in-ground swimming pool algae bloom?
+1
Pool is 23,000 gal., Opened 3 weeks ago, 14 1/2 inches of rain since then, currently 78 degrees temp, fighting algae since opening, chlorine 2 PPM, PH 7.3, 3 opening doses of algaecide in the past 12 days, circulation has been running continuously, very little settling--just a GREEN MESS!! Help, please??

yellow out helps, then vacuum, run filter at least 6 to 7 hrs a day maybe less for your size. shock and keep 2 chlorine tablet in pool skimmer

I agree, heavy shock of chlorine is needed here. The algaecide needs a helping hand on this. With all the rain it is being diluted. Liquid chlorine works wonders, Just pour it in slowly into skimmer after some diluting it. Use care not to burn yourself.

there are many ways to combat that . one is change the sand in your sand filter and i give it a hard shock after doing that. i find that chlorine is too harsh for me so i once cleared substitute plain and simple clorox for the clorine. you also must make sure your water is completely balanced. this is one of the most important things to do to your pool once cleared. i leave mine open all year. i have an above ground 30 ft. round with a deep middle . i have about 40 thousand gallons of water. i run my filter around the clock until it is completely cleared up. cutting off the pump only compound the algae and give it time to reproduce. i then once cleared run at night while we are sleeping.. and off during the day to save energy.. hope this helps

Thank you for your inputs. All that is left is to test for alkalinity and hardness...neither have been a problem in the last ten years with this pool.
