Hot Tub Water Test Kits and Test Strips

Spa Breeze ChemicalsTesting spa water is simple with either a water test kit for chlorine based spas or test strips for chlorine or bromine based spas.

A water test kit is preferred by some as it is said to be more accurate, but the test strips to an equally fine job of alerting the spa owner to a chemical imbalance in the hot tub.

A water test kit comes with a dual chamber plastic vile with level readouts. On one side, a test for chlorine is done by adding 5 drops of OTO to the water sample. On the other side, the test for water pH is done by adding 5 drops of phenol red to a sample of hot tub water filled to the fill line.

The caps are put on and the viles are shaken up to get the correct readout.  Then adjust the water’s sanitizer and pH levels.

Water test strips usually come in viles of 50 strips per container and they come in all sorts of different configurations.  A popular test strip is the one that has 4 tests – chlorine, bromine, pH and alkalinity.  Of course it won’t test for both chlorine and bromine because you should be using either bromine or chlorine as the sanitizer, never mixing the two.  But this allows hot tub owners of both bromine and chlorine based spas to purchase the same test strip without worrying about it in case they eventually want to switch sanitizer after a water change, or to just not worry about being sure they purchased the correct test strip.

The pH levels on the test strip will indicate over/under and allow for adjustment to within the 7.2-7.6 range.  Some suggest it is ok to go as far as 7.8 pH and still be ok.

Keep test strips in a dry place to be sure they do not get moist which can affect readings from the test strip. Follow directions on the container they come in and take the reading right away after dipping the test strip in the water as the colors can change over time after the test is taken.

Hot Tub PH and Chemical Maintenance

chemical for maintaining hot tubGetting the chemicals balanced in the hot tub does not have to be a chore.  Using the Monday-Wednesday-Friday program, spa water maintenance is easy.

Some things to be aware of about pH and hot tubs.

The pH scale goes from 0 to 14 with pH of 7 being neutral.  Anything higher than 7 is base and lower than 7 is acid.

Low pH Problems

Running the spa with low pH is very bad for the hot tub and can cause equipment damage.  Problems with pump seals, o-rings, gaskets, heaters and pumps as well as leaks may be a result of operating the hot tub with water that has low pH.  The solution is to keep an eye on the pH level with test strips and add Spa Up or PH increaser to maintain the 7.4-7.6 ideal pH range.

High pH Problems

This can put mineral deposits on the shell and make your spa feel like sandpaper.  High pH can cause calcium carbonate to precipitate creating a white coating all over the spa.

Operating a spa with high pH also causes cloudy water and is not good for the spa.

Ideal pH Range

The ideal range to maintain hot tub water in is between 7.2-7.6.  Better is between 7.4-7.6 just so there is no danger in the spa slipping into acid water mode below 7 pH.

Have Spa Up and Spa Down on hand and add whichever one is needed to keep the pH in the ideal range.

What about Sanitizer?maintaining a hot tub

This is the other very important chemical for maintaining hot tub water.  Be sure to have enough bromine or chlorine in the water.  The amount of sanitizer can be somewhat reduced if using either a bromine salt system or ozonator.  If using a mineral stick, they can also be reduced, but never eliminated.

QCA Spas has a chemical dispenser for tablets right inside the filter and the amount of bromine or chlorine added can be regulated on the device.  Alternatively a floater can be used to dose bromine or chlorine.
