I installed the swg wih sand filter last Sunday. I am using the supplied test strip the saltwater system came with.
My free chlorine and Total Alkalinty appear to be fine. The ph is what I do not understand. The test strips start with a light orange color and number 6.5. The top number is 8.5 and more brownish orange. When I test my strip has a mostly red and little orange in the middle.
Does this mean the ph is too high or two low? Do I add ph down or ph up?
Also it looks like some more bronzish colored dirt on the floor. Is this bad? I used to just use chlorine and used shocked treatment. Should I ever shock the saltwater system?
Thanks for any help.
