sambucadog Posted May 15, 2006 Report Share Posted May 15, 2006 I just switched from bromine to Nature 2 and want to buy my shock in bulk since I will be adding it more regularly. I have noticed that the price of non-chlorine shocks vary greatly. The best bulk prices seem to be with the oxi shock that is marketed for pools. Is this the same as the stuff for spas? Do companies just package it in smaller amounts and slap the word "spa" on it and get more money? Also, what is the difference between a product labeled MPS and one that is just a potassium monopersulfate shock...I've seen them side by side on th shelves? Is there a proper percentage of potassium monopersulfate that I should be using? Thanks in advance for your feedback! Quote Link to comment Share on other sites More sharing options...

The potassium peroxymonosulphate (Oxy shock) is the same for pools as it is for spas. Yes, spa products tend to be priced higher because they are packaged in smaller containers. I noticed even on the products we have on our shelf, the % can range between 36% active ingrediants to 42.8% but I don't think it would make any difference it what is does - oxydize the pool.

The pool product will drive your pH down. As long as you test and adjust, you should be fine. Prior to each use add 1 tablespoon MPS per 250 gallons. Weekly add 3 tablesppons per 250 gallons.

footsie Posted May 18, 2006 Report Share Posted May 18, 2006 I use Nature 2 and I use dichlor as a shock, do not use chlorine for pools in hot tub, water too hot, needs dichlor. Quote Link to comment Share on other sites More sharing options...

Excuse me, dichlor IS chlorine. But it is a great shock. Dissolves immediately, oxidizes and sanitizes. Quote Link to comment Share on other sites More sharing options...
camfam Posted May 19, 2006 Report Share Posted May 19, 2006 Excuse me, dichlor IS chlorine. But it is a great shock. Dissolves immediately, oxidizes and sanitizes. What footsie is saying is that chlorine for pools (trichlor) is different than chlorine for spas (dichlor). Pool chlorine is much stronger and can damage your spa if you use it long term. I use EZ spa (similar to Nature 2) and dichlor shock. It is easy to use and my spa is crystal clear all the time! Quote Link to comment Share on other sites More sharing options...

DiChlor is also used in pools. It makes a great shock for the same reasons. Quote Link to comment Share on other sites More sharing options...
