HydroSurge Weekly Spa Care | Biofilm Care

HydroSurge Weekly Spa Care is a weekly water care product that keeps your spa clean from the inside out, and this 2 Liter bottle is the value size — roughly 24 weekly doses, or four to six months of supply for most spas. This EPA-registered formula — the well-known "purple liquid" — targets the one place ordinary chemicals can't reach: the biofilm that builds up inside your plumbing and jets. Added once a week alongside your sanitizer, it prevents that buildup from ever taking hold.

Biofilm is the hidden villain of hot tub care. It's a slimy bacterial layer that forms inside spa pipes, and it's notoriously hard to remove once established — it keeps re-contaminating your water, driving cloudy water, odors, and constant sanitizer demand no matter how carefully you dose. Total Maintenance stops that cycle: it keeps the plumbing clean so contaminants can't hide and multiply, and it makes your existing sanitizer noticeably more effective by dispersing bacteria so the sanitizer can reach them.

The result is water that stays crystal clear, soft, and fresh-smelling with less effort — and because your sanitizer works better, you typically end up using less of your other chemicals overall. It also helps guard against white water mold and smooths out pH swings.

Pro Tip: The 2 Liter size is the one to choose if you're on an auto-ship or dealer program. Serum Watercare's Lifetime Jet Warranty is tied to regular weekly use of the 2 Liter bottles through an authorized dealer's auto-ship program — so buying this size and using it consistently is what keeps that jet coverage in force.
