King Technology FROG Algae Blocker 4Pro Pods, 18-Pod Bucket
Drop a pod. Block algae for months.
The King Technology FROG Algae Blocker 4Pro (MPN 01-18-4425, SKU PST-01184425) is a drop-and-go algaecide that ends measuring, spilling, and guessing. Each pre-filled pod carries a concentrated, copper-based formula in a durable fabric pouch, so you just drop one in the skimmer basket and let it dissolve, no jugs to pour and no mess to clean up. One pod treats up to 10,000 gallons and prevents future outbreaks for up to 6 months, and this bucket holds 18 pods to cover a full season of pools.
One Pod, Zero Mess
Forget pouring liquid algaecide and rinsing sticky caps. Each FROG Algae Blocker 4Pro pod is pre-measured in a sealed fabric pouch, so you drop it straight into the skimmer basket with no measuring, no spilling, and no leaking. The pod dispenses within hours and is fully spent inside 24 hours, then you simply toss the empty pouch on your next visit. It is the fastest way to dose a pool without ever touching raw chemical.
Blocks Every Type of Algae
The concentrated copper-based formula kills green and yellow algae and prevents black, yellow, and green algae from taking hold again. Dropped in as a preventative, one pod holds a pool clear for up to 6 months, so you stop chasing blooms all season instead of reacting to them. King Technology backs it with a 90-day algae protection guarantee, a level of confidence you rarely see on a pool algaecide.
Protects Your Pool Surface
Copper algaecides fight algae well, but loose copper can stain plaster, vinyl, and fiberglass. The 4Pro formula is built with 25% more stain inhibitors than typical algaecides and layers in 4X StainGuard, four distinct stain inhibitors that keep the copper in solution instead of falling out onto your walls and floor. You get strong copper-level algae control while your finish stays clean, on every pool type.
Who It's For
Weekly Service Pros
Built for route work. Drop a pod, note the date, and move on, no jugs riding in the truck and no dosing math at the poolside.
Every Pool Surface
Safe to use on all pool types, including plaster, vinyl liner, and fiberglass, thanks to the heavy stain-inhibitor package.
Season-Long Prevention
Use it preventatively at season open and let one pod hold a 10,000-gallon pool clear for up to 6 months instead of fighting blooms all summer.
Green and Yellow Cleanup
Already seeing algae? A pod paired with a proper chlorine level knocks down green and yellow algae and then keeps it from returning.
Why PST Customers Pick This
Pre-Measured Dose
One pod is calibrated for up to 10,000 gallons. No cups, no guessing, no over-pouring, the pouch carries the exact charge every time.
No Tools, No Pouring
There is nothing to open or measure. Set the pod in the skimmer basket and the flow through the skimmer does the rest as it dissolves.
Clean Disposal
The fabric pouch dissolves its charge within 24 hours, then you pull the spent pod out and discard it on your next visit. No residue left behind.
All Pool Types
Rated safe for all pool surfaces and construction, so one product covers plaster, vinyl, and fiberglass pools on your route.
Broad Algae Control
Targets black, yellow, and green algae, the three that plague residential pools, from a single concentrated copper-based pod.
18 Pods Per Bucket
This bucket is stocked with 18 pre-filled pods, enough to treat many pools or hold one pool through repeated seasonal dosing.
Chemical Handling Notice
FROG Algae Blocker 4Pro is a copper-based algaecide. Handle the pods with dry hands and do not open, cut, or empty a pod, keep the fabric pouch intact and let it dissolve in the skimmer. Never mix this product with chlorine, acids, or other pool chemicals in a bucket or feeder, combining concentrated chemicals can generate heat and hazardous gas. Overdosing copper can stain surfaces and cannot be undone, so follow the label dose of 1 pod per 10,000 gallons. Store the sealed bucket in a cool, dry, well-ventilated place away from other chemicals, and keep it out of reach of children and pets. Always read and follow the product label.

Frequently Asked Questions
How many pods are in this bucket and how much water does each one treat?
This bucket holds 18 pre-filled pods. Each pod treats up to 10,000 gallons at the label rate of 1 pod per 10,000 gallons, so a single pod covers most residential pools in one drop while the bucket carries you across a full season of dosing.
How do I use a pod?
Drop one pod directly into the skimmer basket. The pod dispenses its formula as water flows through, usually within a few hours and no more than 24 hours. Leave the spent fabric pouch and pull it out to discard on your next visit. There is nothing to open, measure, or pour.
Will this stain my pool surface?
This is a copper-based algaecide, and copper can stain if it falls out of solution, which is exactly what the 4X StainGuard package is built to prevent. The 4Pro formula carries 25% more stain inhibitors than typical algaecides and is rated safe on all pool types. Stay at the labeled 1 pod per 10,000 gallons, since overdosing any copper product raises stain risk.
What algae does it prevent, and for how long?
Used preventatively, one pod helps block black, yellow, and green algae for up to 6 months. The formula also kills existing green and yellow algae. King Technology backs the product with a 90-day algae protection guarantee when used as directed.
Do I still need chlorine and balanced water?
Yes. Algae Blocker 4Pro prevents and controls algae, but it is not a sanitizer. Keep a normal free chlorine level and balanced pH and alkalinity as you would on any pool. If you are clearing an active bloom, hold a proper chlorine level alongside the pod for the fastest knockdown.
Can I use this on a vinyl or fiberglass pool?
Yes. It is labeled safe to use on all pool types, including plaster, vinyl liner, and fiberglass. The heavy stain-inhibitor package is what makes a copper algaecide safe across those surfaces, so it works on the full range of pools on your route.

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
