A residential spa/hot tub should be drained 2 to 3 times a year, but how do you know when it’s time to do that? Here are some helpful tips and things to look for.
Foaming – Low Calcium levels or organic debris are usually why your spa has a foamy-like substance on the top of the water. There is too much buildup in the water, and it foams because there is no place to go, so it collects in the form of foam. Anything from sweat, makeup, and lotions can be the organic debris that causes this foaming. Even if you don’t see foam, but you see a ring of dirty-looking film around the edge of the spa, that means it’s time to drain and clean.
Cloudy water – Cloudy water can signify that it’s time to drain and clean your spa. When most people see their spa is dirty, they first want to add chemicals to balance the water. This isn’t always the case; adding chemicals may be a waste of money if your spa is too dirty. If you last drained and cleaned your spa a few months ago, try cleaning rather than adding more chemicals.
No Chlorine read – No chlorine reading when you test your water, even though you added it, can signify that it’s time to drain and clean. Even though you have just added Chlorine to the spa, getting a No Chlorine reading may mean that you have what’s called ‘White Water Mold .’WWM’ is a naturally occurring film that is common, and adding more Chlorine can sometimes help but the best idea, if you have added Chlorine already and there is still no reading, is to drain and clean your spa.
So to sum it all up, if your spa shows signs of dirt and grim, and you haven’t cleaned it in a few years, it’s time to give it a good scrub.
