I still don't really fully understand the whole chemical thing. Dichlor vs shock. When do I use what. I also have the nature 2 in the tub.
My ozonator is currently not working I have a new one on order.
Also how often do I clean the filters?
This is what I tell people to do, quick and simple:
Per use:After EACH use add 1 generous teaspoon of dichlor per person. Don't get out and think "I'll do it later", add it as you exit. Don't worry about test strip readings of dichlor, just add after each use. t will sanitize and dissipate so you will have little dichlor the next day but as long as you add EVERY time you use it you'll be in good shape. Also, if you go 3 or 4 days without using the spa add a generous teaspoon or two then as well.
Weekly:Shock once per week with MPS.
Check Ph/Alk once per week. Adjust as necessary.
Monthly:Clean the filters thoroughly once per month. If the spa is getting a lot of use you might take them out mid month and give it/them a 5 minute rinse.
Quarterly:Change the N2 cartidge every 4 months. Thats also
about how often you change you water (±2 months). Depending on your water source you may want to use Spa Defender (metal sequester) with every fill up. If you do, add it upon fill up but wait a day or two to install a new N2 cartridge.
I don't use clarifiers, defoamers, etc unless I absolutely have to. Its not a science project, keep it simple.
