How long do I need to wait between dosing Orenda products?

For best results, there are certain sequences of when and where to add Orenda products, and over how much time.

Wait times for Orenda products depend on what you are doing, and what products you are using. For that matter, wait times and the sequence of the products added depends on many other variables too. But in the interest of keeping it simple, let's go through the basics.

5 Orenda bottles


If PR-10,000 is involved in the procedure, it almost always goes in before other Orenda products. One exception to this would be our unpublished process for black algae removal, where the enzyme purge is added one week prior to chlorine shock and PR-10,000 being added.  Apart from that, PR-10,000 either goes in first, or it immediately follows chlorine.

For the filter purge, PR-10,000 and CV-600 are added at a 1:4 ratio (PR to CV) and can be added in either order, or at the same time. It doesn't matter.

Regular use of PR-10,000

Let's say your pool has extremely high phosphate levels, and you're trying to knock them out with multiple PR-10,000 doses in succession. What's the wait time between PR-10,000 doses? Just wait for the pool to clear and for the cloud to either settle to the floor or get filtered out. Monitor filter pressure and do not let your filter grids become too stressed with all the phosphate dust.  If you're also adding another product, you can add it without a wait time. PR-10,000 is compatible in the pool with all other Orenda products.

And what about the wait time for PR-10,000 after a chlorine shock?  There is no need to wait. PR-10,000 can be added with a chlorine shock simultaneously.


SC-1000 is tricky because if it's added too fast, it will zero out free chlorine. This is why we advise dividing up the purge dose over several days. There are only a few procedures where SC-1000 is used in conjunction with other Orenda products (i.e. the Orenda Startup™, where SC-1000 is used before CV-600, which is added the next day).  Most SC-1000 use is simply an annual purge divided up over 3 or 4 visits to the pool. If your pool requires weekly maintenance, it is only 3 fl.oz./10,000 gallons a week, added directly to the skimmer, gutter, or surge tank.

If you're struggling to hold chlorine after using SC-1000, try grabbing a bucket of pool water and dissolving a few pounds of calcium chloride, then adding it back into the pool. This will give SC-1000 some new calcium to bind to.

Regular use of SC-1000

Most pools do not need to do weekly maintenance with SC-1000, unless the tap water contains high metal content (like well water, or areas around the Great Lakes), or if the pool continues to struggle with metal stains, carbonate scale, and/or other calcium issues. If you are adding SC-1000's weekly dose, add it to the skimmer/gutter/surge tank to give it time to spread around and find metals and minerals. Otherwise chlorine will attack it and you can lose some chlorine that way.  Generally speaking, weekly SC-1000 doses are small enough that chlorine loss is negligible.

CV-600 or CV-700

Most Orenda procedures involve our enzymes. They almost always go in after something else. In the green pool cleanup, CV-600/700 is added after PR-10,000, which is added immediately after a non-stabilized chlorine shock.  In the spring opening procedure, CV-600/700 is added as the water is warming up, either alongside SC-1000's annual purge dose, immediately after a PR-10,000 purge, or both.  The spring opening procedure involves using all three products (PR, SC and CV) as the water warms up.

Regular use of CV-600/700 

One of the most common questions we get is "will chlorine kill CV-600 enzymes?" or "what is the maximum chlorine level to use with CV-600 enzymes?" The answer, to the best of our knowledge, is to keep your chlorine levels below 20 ppm. If you are shocking the pool around the perimeter, give it a few minutes before adding CV-600 or CV-700. Add the enzymes to the skimmer/gutter/surge tank.  If you were to pour our enzymes in the exact same spot as liquid chlorine, for example, the concentration of chlorine right there might be too high for the enzymes.  So spread it around and use dilution to your advantage.


Our clarifier is not used as a primary chemical in our procedures, but is useful in conditions where particles land in the water. This includes pollen season, wildfires and dust storms. If you're using CE-Clarifier alongside other Orenda products, add CE-Clarifier last.


In general, all Orenda products are compatible with one another. There is usually no wait time between our products. However, when superchlorinating, there can be a wait time or the need to spread around chemicals in different areas of the pool to avoid high concentrations of chlorine. Keep this in mind unless specified otherwise in our procedures.
