Sicce 펌프 스케일 제거제

I was skeptical about how well a natural descaler would work, but this powder cut through the built-up gunk in my pump within minutes. My equipment looks and runs like it's brand new now.

My skimmer had been losing flow for weeks and I figured I'd have to replace it. Soaked the impeller in this powder for a few hours and the gunk just rinsed right off, flow is back to normal. Love that it's biodegradable too, no worries about what's left in the water.

Dropped my return pump in a bucket with a scoop of this and the impeller was spinning like new after 20 minutes. It's a biodegradable powder, so I didn't worry about rinsing it down the drain afterward. My flow rate is finally back to where it was when the tank was new.
