I just purchased a house with a pool and have been performing the following tests twice a week for the last two weeks, Chlorine Residual, pH Test, Acid Demand Test and Total Alkalinity. Up until a few days ago everything tested fine, then there were a couple days with 100 degree temps and now I have a nice bed of mustard algae. Tested with a new test kit last night and discovered I had no chlorine the pool. In a panic I ran to the pool store Leslie’s and they sold me a two pound bottle of yellow out and six pounds of fresh n clear to shock the pool with.
My directions were:
Backwash the filter, an adventure all its own.
Recharge the filter with D.E.
Set the pump to run 24/7
(Not in directions but I brushed the pool the best I could)
Sprinkle Yellow out around the perimeter of the pool (2 pounds)
Wait five minutes and add two pounds of Fresh N Clear to the pool
Wait 12 hours and add two more pounds of Fresh N Clear
(Again I brushed the pool, most of the algae appeared to be on the bottom of the pool now and less on the walls and some of it did not brush off well.)
Wait 12 hours and add two more pounds of fresh N Clear (This last shock is supposed to take place tonight.)
Once water is clear bring them a sample of the water and they would probably give me some sort of first aid product that will eat the dead algae so my filter does not have to filter it all.
These were my test measurements to the best of my recollection. I will have to check and update when I get home from work today.
.5 ppm FC
.5 ppm TC
.0 ppm CC
8.2 pH just noticed I didn’t do the Acid Demand Test and the Base Demand Test
Most of my pool is shaded by Oak trees; probably ¾ of the pool is in the shade the majority of the day.
So, I found out while backwashing my filter the water shoots out a 3” pipe at the bottom of the filter and hits a wood fence about 6 inches away then runs down my yard and into my neighbor’s driveway. Probably not a good impression on my new neighbors.
QUESTION: Is it acceptable to water you yard with the water as you backwash the D.E. filter?
Once I get the pool cleared up I will definitely do a better job at taking care of it after reading some of the posts on this site. For now I am spending my time painting and cleaning up the new house so I can actually move into it.
