Summer is genuinely the toughest season for hot tub water chemistry. UV light burns off sanitizer, ambient heat stresses your equipment, and more frequent soaking loads the water with organics faster than usual. This guide explains what’s actually happening and what to adjust.
Low calcium hardness is one of the most overlooked hot tub chemistry problems. Soft water aggressively corrodes surfaces and equipment, and fixing it is simpler than most owners expect. This guide covers the target range, the risks of ignoring it, and exactly how to bring calcium hardness up.
A hot tub party can wreck your water chemistry in one evening if you go in unprepared. The fix is a simple before-during-after routine: pre-treat your water, set chemical levels higher than normal, and shock immediately after everyone clears out. Here’s exactly how to do it.
Spring startup is one of the easiest things to get wrong — and one of the most satisfying to get right. This guide walks you through the exact steps to flush, drain, refill, and rebalance your hot tub after winter so you’re soaking safely within a day or two.
If your hot tub pH keeps creeping up no matter how much pH decreaser you add, the problem is almost never the pH itself. High total alkalinity and aeration are the real culprits. This guide explains why it happens and what to actually do about it.
Not all hot tub water testing methods are equal. Test strips are fast but rough, liquid kits are more accurate, and digital readers are precise but pricey. Here’s how to pick the right one for how you actually manage your hot tub.
Soft water in a hot tub is more damaging than most owners realize. Low calcium hardness eats away at acrylic shells, corrodes heater elements, and causes persistent foam. This guide explains what target range to hit, how to raise calcium safely, and how to spot the damage before it gets expensive.
Cloudy hot tub water usually comes down to four culprits: low sanitizer, unbalanced pH or alkalinity, high calcium hardness, or a clogged filter. Testing your water and working through the causes in order will clear it up faster than dumping in clarifier and hoping for the best.
