Keeping a hot tub’s water chemistry in check is a routine task that many owners find tedious, but it’s necessary to protect the equipment and ensure comfortable soaking. The Leisure Time 22339A Spa Up pH Increaser is a product designed to address one specific part of that balancing act: raising low pH levels. After spending time with this 2-pound container, it’s clear this is a straightforward, no-frills solution for a common problem.
In real-world use, this product is as simple as it gets. You test your water, find the pH is too low, and add a measured amount of this granular powder directly to the water while the jets are running. It dissolves relatively quickly, and within a few hours, you can retest to see if you’ve hit the target range. This isn’t a product that requires complex mixing or pre-dissolving, which is a plus for anyone who just wants to get the job done without fuss. The 2-pound size is manageable and should last a moderate amount of time depending on how often you need to adjust pH, though heavy users or those with larger tubs may find it runs out faster than expected.
Functionally, the key feature here is its specific purpose: raising pH without significantly affecting total alkalinity, which is a common concern with some other pH increasers. Many generic pool products can spike alkalinity, leading to cloudy water or scaling. Leisure Time’s formula is designed to minimize that side effect, though it’s not entirely immune. In practice, you might still see a slight alkalinity bump, so it’s wise to test both levels regularly. It’s also compatible with various sanitizers, including chlorine, bromine, and even biguanide systems, which adds flexibility for users who switch between sanitizer types.
However, there are limitations worth noting. One trade-off is that this product works relatively slowly compared to some liquid alternatives. If you’re in a hurry to balance the water before a soak, you might find the granular form takes longer to fully dissolve and circulate. Additionally, the 2-pound container lacks a built-in scoop or measuring guide beyond the basic instructions on the label, which means you’ll need your own measuring spoon or rely on weight estimates. This isn’t a deal-breaker, but it adds a minor inconvenience. Another point is that the price per pound is slightly higher than generic sodium carbonate or sodium bicarbonate products you might find at a pool supply store. While those alternatives can work, they often lack the pH-vs-alkalinity balance that this product aims to provide, so the cost difference may be justified for some users.
When compared to something like a simple baking soda or a generic pool pH increaser, the Leisure Time product sits in a middle ground. Baking soda is cheaper and raises alkalinity more than pH, which can be useful in some situations but not ideal for low-pH, low-alkalinity water. A generic pool increaser might be cheaper but could cause more alkalinity drift. This product tries to be more targeted, and it generally succeeds, but it’s not a dramatic improvement. For most hot tub owners, the difference will be subtle, and the choice may come down to convenience and brand trust rather than performance leaps.
As for who should consider this product, it’s a good fit for hot tub owners who are already comfortable with regular water testing and want a predictable, dependable way to raise pH without introducing extra variables. It’s also suitable for those who use non-chlorine sanitizers and need a compatible product. On the other hand, it’s less ideal for beginners who might be overwhelmed by the need for precise measurements and patience. If you prefer liquid chemicals for faster results or want a bulk solution to save money, a generic alternative might serve you better. Also, if your water is consistently low in both pH and alkalinity, you may need a product that raises both, and this one might require you to supplement with an alkalinity increaser separately.
Overall, the Leisure Time 22339A Spa Up pH Increaser does what it claims without fanfare. It’s a reliable tool in the hot tub maintenance kit, but it won’t revolutionize your routine. It’s worth considering if you value chemical balance precision and compatibility, but it’s not a must-have for everyone. Realistic expectations are key: it will raise your pH, but you’ll still need to monitor other parameters and accept the minor inconveniences of granular application.
