Hi All,
Firstly, what an amazing community this is. As a new pool owner, I don't feel as anxious about managing our pool going forward having seen what's happening here at TFP!
Seeing as I have made my first 'mistake' I wanted to check in with people regarding getting my pool on track. We moved into this house a few months ago and am now at a stage of taking control of the pool situation. It is peak winter here in Brisbane Australia but temps only get as low as ~7 degrees celsius with highs in the low 20s. I have noticed the pool has a reasonable amount of black algae. I received my test kit and started logging results in pool maths and made the mistake of taking my CYA from 45 to ~75 before getting across the details on dealing with black algae (SLAM and brush), so I guess my chlorine consumption for SLAM will be significantly higher which I have accepted (a valuable lesson in taking my time reading the content available here before following the poolmath advice).
What I want to confirm is:
Brenton.

What I want to confirm is:
- I have noticed when I backwash to waste I still see the water moving through my chlorinator (SWG) back into the pool(a small amount, but enough for me to be concerned around filter waste going back into the pool). I suspect I need to replace my spider gasket in the multiport?
- If I do have to replace the spider gasket in the multiport, I am concerned I may damage/break the intake pipe that runs from the pump to the multiport as it probably hasn't been unscrewed in 10+ years?
- I have ~10 litres of old liquid chlorine that is probably 6 or 7 years old. Is there any risk in using this to kick off the increase in FC for the SLAM backing it up with new liquid (ensuring both have no CA). It looks like I can access new 100 or 125mg/L liquid chlorine easily.
