That's an interesting point you make @tim5055. Since I disabled the UV light this week I noticed a significant decrease in the amount of chlorine I have been adding to maintain a 3-7 ppm FC range.

I guess the good news is that the water doesn't puddle. I have a rock wall on the back of the pool that comes in contact with the pool water. Algae tends to form over time. - - - Updated - - - I have passed OCLT multiple times but I had the UV operational. I too thought it may be pollen...

Thanks for the feedback. Just a clarification, when you say fixtures, I'm assuming you mean anything that comes in contact with the water? If that is the case then that very well is part of the answer. I did have some algae on the stone that I removed just a couple of days ago. I guess I...

I'm looking for some input as to why algae keeps reappearing after Slamming and successfully completing OCLT. This has happened twice now and I'm puzzled why this is happening. Thanks to this forum I had an algae free season all last year and want to have a repeat this year. After...

Thanks for your reply. I checked the PH of the tap water and it is 7.7. I'm thinking the spillover from the spa is driving it up. I will probably try adjusting the valve and see if that helps. - - - Updated - - - Not very often now that the temps are considerably lower. In the winter I...
