Is it possible to get rid of algae without draining your whole pool?
We just had a new in ground, 40x16 pool put in 2 years ago. In August of last year, algae started overtaking the pool. After constantly bringing water samples in (literally on a weekly basis) to the pool company, we ended up spending hundreds of dollars on chemicals that the pool company kept swearing would work on killing the algae, but it didn't. Due to it being August and we were going to be closing the pool for the season within a few weeks, my husband decided to have it winterized and we closed it up.
We just uncovered the pool a week ago. Last year, it took about 5 days for the entire pool to go from the murky blackish color it looks like when you first uncover it (mesh cover, btw), to crystal clear. After 2 days of it not getting any better, we figured it may be the sand in the new filter. We called the pool company and they said that if it wasn't clean, then the sand would need to be replaced. OK, so I called a contractor and he quoted $315. Well, for that price, my husband figured we could just by a DT filter, which he knows more about. Prior to doing this, the light kept going out on the Intellichlor Chlorine generator. And yes, I changed the fuse, but for some reason, it lasted 2 days and then the lights went out again. This time, when I changed the fuse, no lights come on! UGh!
So we tried to trouble shoot....
My husband replaced the 2 year old sand filter with a new DT filter. We figured that the algae in the pool may get filtered out. We bought the size filter for a 40+k gallon pool, even though we only have 28k gallons. My husband put in the superchlorination and algae chemicals (which the instruction manual for the filter said to do) and we left the filter on over night, hoping there would be a major change this morning.
Unfortunately, without the lights on the chlorine generator, I cannot accuately check the levels of salt and chlorine in the pool. So this is another problem I do know that when the generator was last reading (prior to the new filter install), all lights were green and we had it set at 40% for running.
The pool looks exactly the same! It's been a week and after reading through some posts on this thread, I see that many people have resolved their algae problem by draining their pool (if not all the way, half-way).
QUESTIONS: (I know...long winded, but I felt I needed to explain everything so there was less back and forth posts)
1) Does anyone here have a suggestion on how to get rid of an entire pool full of algae WITHOUT draining it?
2) Besides for replacing the fuse, what else can we try to get the 2 year old Intellichlor generator to display lights?
Thank you all! We are HOPING to go swimming in the pool sometime soon
