Service at Tongs has always been awful in my experience. Their prices and organization are awful too. That old guy on their IG seems to be the happy go luck type tho, maybe ask for him if you get stuck there lol
when I used to clean mine, I would just pressure wash, takes 2 minutes to clean em all. Tbh I haven’t even pulled mine out in 9 months tho 😂 can’t keep nutrients up anyway seems pointless lol
