In Waterbear we trust

Just wanted to send a note of thanks for Waterbear's contributions to the forum.  We've had a 7000 lt swim spa for a few years now and I've always struggled with water quality.  Based on his posts this is what I have done...

Cleaned filters and pipes
Emptied the spa
Refilled spa
Bought a Lamotte ColorQ 2x PRO 7 testing kit
Balanced Calcium Hardness
Balanced pH and Alkalinity
Added 260 grams Sodium Bromide (bought in the USA and shipped down under - not available here)
Shocked with 500 ml Liquid Chlorine (12.5%)

This morning, after adding the Sodium Bromide yesterday afternoon, the test results are as follows:

Bromine = 6 ppm
pH = 7.7
Alkalinity = 94 ppm
Calcium Hardness = 190

Not perfect, but not too bad for an accountant playing with his new chemistry set.  The Bromine and pH look a little high, but I'll test daily and see how it shifts.

Moving forward my plan is:
- Experiment with the bromine tablet dosage in a floater
- Shock weekly with a cup (250 ml) of Liquid Chlorine

Unless of course, Waterbear tells me otherwise...

Thanks again,

Chris
