Hello and thank you for any help in advance!
We bought a PermaSalt pool last year and decided to convert it to chlorine at the beginning of this season using the method on the website. Due to some family reasons, the pool got in bad shape (algae!!) towards the end of the season. We ended up closing it green knowing we would have some work when opening it in the spring.
Well, I did lots of research on this site, purchased the Taylor K-2006 tester, and took out the PermaSalt tube and replaced it with normal PVC.
I used the test kit to do all the initial tests to see where we started they were:
Did some adjusting on the PH to settle at 7.2 and then added the stuff needed to target a CYA of 40. Then started the SLAM process using PoolMath with an FC target of 16. Last weekend spent two days of testing FC every 1-2 hours and adjusting. Since getting a better handle on how quickly the FC changes (hasn't been all that sunny lately) test it 2-3 times/day. Been brushing, vacuuming, and backwashing daily.
Here are the couple tests I ran yesterday, a week after the process:
CYA: 30-40 range
Here's where I need help. It doesn't seem like much progress is being made. At this point, I was hoping to at least have the algae turn gray-white and beginning to die! I've added some pictures (all taken with grey skies) of what the pool looks like this morning. The algae always seems to settle in this same spot in the middle of the pool.
Also, the weather in Indiana has been a little all over the place. The water is still in that 55 degree range. Could that be slowing the process?
