water level is to the bottom of head rest.i will look at the other things you mentioned.thanks

anyone know what might be causing this.the spa is a 2000 caldera tahitian.when the number one pump turns off in either first speed or second speed.the water gurgles a lot back through the filter.it does not do this with the number two pump at all.i checked and don't have any visible leaks. i dont think its trapped air.the spa has been up and running for a month now.im worried that when it does this that it is putting some of the contaminants back in to the water from the filter.

Yes.Dichlor-then-bleach method.I don't normally use MPS. someone didn't rinse there swimsuit out good and was just trying to see if it would help.Thanks for the information

I'm using the bleach method. If I add some MPS and don't have the reagent to stop the interference.How long do I have to wait to get a true chlorine reading. THANKS.

Thanks for the information. I ended up getting the k-2006 kit.very nice kit I have to say.

Hello. whant to test. PH AL Hardness MPS TDS Free available chlorine residual will be using the nature 2 and the way they recommend the treating of the water dichlor will be used for shocking. Is there a test kit that test all of the above or are separate kits needed.please recommend best way to go about this. THANK YOU.
