I have been traveling a bit this summer and have not been very good about my pool monitoring. I log most of my testing into pool math and my finish is EcoFinish. I administer liquid chlorine daily into my pool using a Stenner pump and a timer. Thanks to this site I have not a problem with my pool chemistry for quite some time. I took that a little for granted and slacked on the daily adds to the pool. My pool has two things going on please see the pictures to see the small black spots along the shady side of my pool. I think this may be black algae. I've had a hard time getting my free chlorine up to SLAM levels and bought some Dichlor at the local shop. Now my FC is sky-high. I continue to brush the algae twice daily and I am hoping this takes care of it. My deep end is 10 ft deep and it is not easy to get in and scrub the spots. I am using a brush on a pole.
The second issue I want to deal with is a few rust spots that have been caused by two bolts and a drill bit left behind by a contractor replacing a fence. I purchased some vitamin C from Costco today and will attempt to crush some tablets and put them in a skimmer sock and see if these help the rust to fade. Is there anything more that I need to know before I do this?
Any input or advice is appreciated. So grateful for this site and the availability of the pool test kit. You make it so much easier to have a pool!
