We had a stubborn algae issue. The local pool company said to shock, then next day add algaecide then last step clarifier. Since clarifier causes dead algae to
clump together in order to manually vacuum up on waste, we figured that is a lot of water waste ( 20 x 40 ft pool). Also, if you miss some of this sticky substance, your
(sand) filter might catch small missed sticky pcs which is not great for it.
We called another local pool company who gave great advice that worked. No Clarifier Recommended!
First we brushed pool sides and bottom and shocked pool with 10 gallons of liquid shock raising FC to14ppm. Then put on filter 12 hrs. We backwashed and rinsed filter after the 12 hrs. The pool was still green so we waited 48 hrs and again brushed and shocked again and ran filter 12 hrs and backwashed and rinsed it again. Still green but lighter. Then repeat brushing, shock but used 5 gallons of shock third time and ran filter 8 hrs and backwashed and rinsed it . Then the pool turned blue and clear at bottom. We were able to see very little small dead clumps at bottom and I mean maybe 18 in x 12 in size and targeted it daily with manual vac. on waste. Use manual vac with wheels not brushes as the wheels move quicker thus less water waste and the wheels do not disturb the algae dust. Took about 90 seconds for three days every morning.
Doing this method enabled us to waste very little water. Also, we did not have to worry about the filter clogging with gummy clarifier if we missed a spot.
This was recommended as the 2nd option we received by a local pool company.
I forgot to mention, the 2nd pool company said we did not need the algaecide as the FC eats the algae and keeps it away anyway but we had already bought it so we threw it in .
Our sand filter did a good job of picking up most dead algae but we did have new sand , added a year before.
We now keep our Free chlorine especially in check as well as PH and alkaline levels . A miserable lesson to learn.
