Hi, First year owner. Managing my own chems. I thought I was keeping up on everything over the winter. Recently, as I let the water evaporate down to fix some grout cracks noticed a pretty significant scum line at where the water level normally sits. I used the magic eraser pads and they seem to knock it down pretty good. Will need to hit the grout section with something else though. I have two questions, is there anything in the water chemistry that I can do to help with the scum line now? Second question, what do I need to do differently in my maintenance to prevent this in the future?
I have always had to struggle with maintaining the pH this last year. Wants to drift on me. I don't think I let it go beyond 7.8, but it did tend to rise to that level often. Only other parameter I missed on this year was chlorine. I use liquid chlorine and once the temperature turned to colder I under estimated how little the chlorine leaves the pool. Using my normal application up through October it spikes to over 10 ppm, maybe as high as 20. Took about 3 months and a lot of rain for it to come down to a normal reading. Kept the algae away at least.
What did I do wrong and is it best correct? Thanks in advance.
