Rendezvous Calcium Hardness Up - Liquid

Rendezvous Calcium hardness up - liquid calcium hardness increaser

Rendezvous Liquid Calcium Hardness Up

Rendezvous Liquid Calcium Hardness Up is a unique product used to increase the calcium hardness in your spa or hot tub water.

Rendezvous Liquid Calcium Hardness Up economically & effectively raises calcium hardness (low calcium hardness can lead to quicker corrosion of spa equipment & excessive foaming)  No mixing, just pour it in. 

Remember that good water balance is important for you and your spa and equipment.

Follow label instructions.  For best results retest after about 3 hours (when initially adjusting calcium hardness).  Always test your spa or hot tub 1 - 2 times per week.

Use 1 oz. Liquid Calcium Hardness Up per 700 gallons of spa water when spa is filled or completely drained & refilled to raise the calcium hardness about 7 ppm.  Test the calcium hardness of your water first to determine how much it has to be raised.

100% compatible with any and all spa care systems: chlorine, bromine, biguanide (BaquaSpa or Soft Soak), Nature2, SpaFrog, Pristine Blue, AquaFinesse, ozone.

Rendezvous  Liquid Calcium Hardness Up is poured into the water only as needed.  Test regularly and adjust especially when fresh water is added.
