frequently asked questions

Find answers to common questions.

It’s a copper based dry algaecide in unique pods that can be used to cure an algae outbreak (yellow or green) or prevent algae (yellow, green or black) from happening for up to 6 months.

Typically, in a few hours but no more than 24. At that time, the empty pod will float to the top of the skimmer. You can easily remove and discard it on your next service call.

When you use FROG Algae Blocker 4Pro as a preventative application, start with a clean filter.
Do not clean or backwash the filter for at least 2 weeks after using a pod.

Make sure the bucket is sealed and always store in a cool, dry, well-ventilated area until ready to use.
It’s important to keep the desiccants in the bucket, do not discard them.

It has a 4X Stain Guard – 4 distinct stain inhibitors that keep the copper from falling out of solution and staining surfaces.

They both use the same copper formula but PoolRX uses less so you often need a booster to keep the pool algae-free for 6 months. They also have a much larger footprint and have to stay in a pump or skimmer basket for 6 months while FROG Algae Blocker 4Pro dispenses within 24 hours with no booster needed.
FROG Algae Blocker 4Pro also contains 25% more stain inhibitors so you can use it on smaller pools than PoolRx’s products and has much less chance of staining that PoolRx’s product line.

This rarely happens. In our vast experience we have only seen copper cyanurate at CYA ~ 300-400 when there were dramatic pH excursions from normal conditions.

We haven’t seen any foaming at all in any of our testing when the algaecide is introduced through the skimmer basket due to the metered dissolution of algaecide from the pod and also the filter being downstream of the skimmer.
