Looking to buy Pool & Hot Tub Water Testing Strips?

Testing the chemical levels in your aquatic paradise is not the most fun task (who wouldn't rather be practicing their diving?!), but it's essential to be in the know so you can adjust the chemicals accordingly - otherwise you run the risk of the water going cloudy, or even turning green! 

Spanning pool water test strips and hot tub water test strips alike, OnBuy's virtual shelves are home to an enormous array of water testing strips - and with offerings from water testing experts LaMotte, finding the perfect solution for your set-up will be smooth sailing. 

The wide range of test strips for swimming pools and hot tubs on offer spans ever-useful individual pool water test strips (think pH tester strips and chlorine testing strips) - or perhaps you want a water test strip that'll do several in one fell swoop? We've got you covered there, too!
