My pool suction was fine but a month or so ago I noted that my barracuda was geeting stuck in corners. Now my suction is very poor. No bubbles at return. 1 year old 150 sqft Pentair cartridge. Cleaning did not help. It was dirty though.
Of note I just took over from my pool guy because he was unresponsive to questions about how he was balancing my pool.
On testing I had 0 CYA and have been adding it over the last two weeks via a sock by the return. Also the pressure guage is shot (despite being 1 year old) and a replacement is on the way.
where do I start?
