I am about to install an aquarite SWG 40,000 gallon system and want to make sure I have everything setup before hand. I've seen a lot on here about getting the salt level right but I'm not seeing lots of options for testing the salt level. I found a digital test for over $100 but dont' really want to spend that much if I don't have to. I read here that the strips are iffy at best so not sure I should go that route. I dont have the option of taking samples to be checked by someone because of where I live. What can you recommend? I am planning on buying a better multi test kit than I have right now also so if there is a combined kit that does salt that would be great.
Also is there anything else you would recommend doing or having before I install this thing?
