FROG DropH pH and Total Alkalinity Decreaser
Drop your pH into range, fast.
FROG DropH (MPN 01-14-6200, SKU PST-01146200) is King Technology's pH and Total Alkalinity decreaser for hot tubs and swim spas. When your test strip reads high, you pour a measured dose using the built-in TruDose Cap and DropH pulls pH down into the ideal 7.2 to 7.6 range so your sanitizer works at full strength and scale stops forming on your shell and heater. One 3 lb bottle treats a full season of routine pH corrections on most spas.
Why PST Customers Pick This
Lowers pH and Alkalinity
One product corrects both high pH and high Total Alkalinity, so you carry a single bottle instead of two separate chemicals for spa water balance.
TruDose Cap Dosing
The built-in TruDose Cap and the dosing chart printed on the bottle tell you exactly how much to add. No guessing, no separate measuring cup, no mess.
Protects Your Sanitizer
High pH cripples chlorine, bromine, and mineral sanitizers. Pulling pH back to 7.2 to 7.6 restores their kill power so your water stays clear.
Stops Scale Buildup
Balanced water keeps calcium scale off your acrylic shell, jets, and heater element, protecting the equipment that is expensive to replace.
Any Spa, Any Chemistry
Works in any size hot tub or swim spa and with any sanitizing chemistry, including chlorine, bromine, and salt water systems.
Fast Acting
Add with the jets running, circulate 10 to 15 minutes with the cover open, then retest. Most corrections land in range on the first dose.
Safety and Handling
FROG DropH is an acidic dry chemical (sodium bisulfate) that causes serious eye and skin irritation. Wear eye protection, add the product to the water and never add water to the product, and keep it dry and sealed in storage. Never mix DropH with chlorine, bromine, or any other chemical, combining acid with these products can release toxic gas. Add only to an unoccupied spa with the jets on, and keep out of reach of children.

Frequently Asked Questions
How do I know how much FROG DropH to add?
Test your spa with FROG @ease Test Strips first. If pH reads high, match your spa volume and current pH to the dosing chart printed on the DropH bottle and measure that amount with the TruDose Cap. Add it to the water with the jets running, circulate 10 to 15 minutes with the cover open, then retest and repeat if needed.
Does this also lower Total Alkalinity?
Yes. DropH lowers both pH and Total Alkalinity at the same time. Bring Total Alkalinity into the 80 to 120 ppm range first, since alkalinity buffers pH, then fine-tune pH to 7.2 to 7.6. Correcting alkalinity often brings pH most of the way down on its own.
Can I use DropH with my chlorine, bromine, or salt spa?
Yes. FROG DropH is compatible with any sanitizing chemistry, including chlorine, bromine, mineral, and salt water hot tubs and swim spas. It only adjusts pH and alkalinity and does not interfere with how your sanitizer works. Add it to the water separately, never pre-mix it with your sanitizer.
Why does high pH matter?
When pH climbs above 7.6, chlorine and bromine lose much of their sanitizing power and your water can turn cloudy while scale forms on the shell, jets, and heater. Keeping pH at 7.2 to 7.6 keeps your sanitizer effective, your water clear, and your equipment protected.
Can I use this in any size spa?
Yes. FROG DropH works in any size hot tub or swim spa. The dosing chart and TruDose Cap scale the amount to your water volume, so the same 3 lb bottle serves a small two-person hot tub or a large swim spa, you just add more per dose on the bigger unit.

Let customers speak for us
Ease of purchase replacement part took care of the problem
Received the correct replacement part. Not a real tough job. Part works great!
Better than the PA version at fraction of the cost.
Just what I needed for my syllent pump that comes with no Jacuzzi pump coupler. Do need a 1 1/2x1 1/4 reducer but everything will work out just fine..
This product seems to work great so far! I’m only two days in but the leak around my steps seems to have been completely stopped after applying this
All went well. Fast shipping AAAAAAAAAAA++++++++++++
Our pool and spa are over 25 yrs old. When the spa air button stopped working, we found that it was no longer avaliable. We did some online searching and found that this was a good replacement option and found it on the PST Pool Supplies website. We ordered it and once it arrived, we were very happy that we were able to install it and it worked fine.
Exact replacement Weir door that fit perfectly! Solved the problem of my old worn out doors!
Excellent price on well built wet end. Shipping was fairly fast as well
I installed the new wire with no problem fit right in and clamp her down like they took the old one out works great now
PST Pool Supply Company is a wonderful company to do business with. The customer always comes first with them.
Thanks
