Those rocks look like Moss Rocks. I also have Moss Rocks for my waterfall and part of my pool wall. Are you sure it is algae and not moss starting to grow. I am pretty sure you have nothing growing below the waterline. I use a spray bottle full of bleach and a nylon brush to remove the moss off...
A 25% increased on your normal filter psi. For example: At 8 psi, you would backwash at approximately 10 psi. A 2 psi increased of 8 psi is approximately 25%. I am an old fart, so I am using math from the 60's and 70's. Good luck
I am a noobe, but after cleaning my Pentair DE Plus Filter 2 days ago, the spring with the brass nut (picture #2) should be compress together. I will let the experts chime in and correct me if I am wrong.

I am a newbie, only had my pool for about 4 months. I would recommend that you buy a decent test kit like the Taylor K-2006 or the TF-100 for starters. What were the rest of your pool water results.

Will add approximate 87 oz of bleach in accordance with PoolMath Calculator. They wanted me to add 4 more tablets, but I think I will stick with bleach for now. Thanks for you help. Hoping I screw up the CYA Test. Will test again tomorrow.
Pool has been filled for about 48 hours. I currently have 6 gallons of 10% liquid bleach and 8 pounds of 20 Mule Team Borax. PB stated I could go swimming today. I wanted to test the water before I went to pool. Should I try to bring up the PH to 7.4 or leave it alone. Rain water is no problem...

Pool is about 17,000 gallons
