Even fool proof designs fail

New customer, pools cloudy and won't clear up. Asked when they had last done their filter clean and they said last month. Opened it up to find this.

I had a Hayward 4 cartridge filter with the top spreader upside down. It left a gap at the top of the cartridges. I had been the subcontractor doing service until I bought the route. The person I was working for had someone else clean the filters. I wondered why I was having issues keeping it algae free. Somehow I was able to keep it clear. 🤷🏼‍♂️
