The purple color goes away in 3 days, meaning it breaks down and not protecting boiler.Prefer 3-way boiler cleaner even though more expensive.

Bought based on price point. EXACT same review as the first review. Blue floaters. Smoked a two year old pump and coated the two heated exchangers in my system. Complete garbage!!

Bought this product to treat my water in my outdoor wood boiler. Now as you can see the blue flakes are pouring out of the system. I can’t get he plate exchanger to operate. It has trashed a 3 year old plate exchanger. DO NOT USE THIS junk!
