Greetings. This is my first post to this forum and I have two issues for which I could use some advice. My 30,000 gallon in ground pool uses a Pentair Triton II TR-100 sand filter and I run the pump 12 hours per day. I also use a clarifier after every backwash as it seems to help keep the water looking clean and clear. The sand was replaced one year ago. My questions:
I appreciate your feedback.

- I can go for weeks or months without backwashing and the pressure gauge never seems to rise. I've replaced the gauge with a new one in the event it was faulty but no change. Shouldn't I see pressure increase when it is time to backwash?
- When I go for a week or two without brushing the sides of the pool, green splotches can appear mainly on the walls but the water is still sparkling clear. I've had the water tested and chemical levels are optimal. My service claims that this is just organic material "since it brushes away easily" but I am not convinced. Is there any truth to this or can it be an algae bloom? They also say to run my filter longer including 24x7 for the next several weeks during the rainy season.
I appreciate your feedback.
