Ok, here is the situation! We bought a Caldera spa - Niagara model. I'm going to write out everything that I did so there is a clear picture of whats what.
It was hooked up on Friday and filled that same morning. I took my water sample in, they gave me all my chemicals to balance the water. So I following their instructions which were :
2 cap fulls of Metal Guard
4 cap fulls of Non- Chlorine shock ( Brand name Spa Magic )
2 tsp Bromine Granular
Run the clean cycle
Add 1 capfull of PH Down ( water test showed slightly high PH)
Run the clean cycle again
Test with strip
The strip comes back with low bromine ( didn't seem to register on the strip at all, and I'm told to add an extra tsp of granular bromine and I"ll be good to go).
That night my son takes a look and says he thinks it has a green tinge to it, I didn't see it, we use the spa, and when done for the night added 2 tsp of bromine granular. The following morning the water is green but clear.
I email the spa guy and he says its algae so to do the 4 cap fulls of shock and 2 tsp of bromine again. Says I should see an improvement in a couple of hours and to test a little more often to make sure the bromine is at good levels and to shock once a day to clear up the algae. So I do this. Since we're out and about and near the spa place I bring in a sample just to be sure. Water lab test comes back with 40ppm bromine, and my water is still sporting a lovely St Patricks Day green colour. My test strips aren't showing anything still although perhaps it was bleached by the high levels. ( As an aside I did a little experiment just to see if perhaps the test strips weren't working and dissolved 1/2 tsp of bromine into half a cup of water, the test strip came back as dark purple..so I don't know )
The spa people tell me to drain the pool as those high levels of bromine may damage the shell. So, ok I drain it, wipe it out fill with new water, follow the same start up chemical process as before. Water looks great!
Because I"m paranoid, I take a sample in the next day ( yesterday ) just to be sure before I add bromine and to grab new test strips figuring the others were crappy. Water test comes back, shows .75 ppm for bromine and PH a litle high..everything else is great. They gave me a different brand of shock to use as well as the other was a new product they started carrying.
I go home, take a new test strip and test the spa water before I treat it and the test strip reads high bromine. And to add insult to injury the water is green again. So I email spa guy and tell him the strip is showing high bromine but I haven't added any since the day before and its turning green again. So he advises to just shock it ( 2 cap fulls ) and skip the bromine for now if the strips are showing high levels. So I do this. They are now thinking its high mineral levels turning the water green and advise to take the mineral cartridge out. So I do.
I went back today with a water sample and both brands of test strips. They run 2 separate water tests which come back with consistent readings of 1 ppm of bromine give or take,I have them do the test strips there out of the same water sample but my strips show high levels 10-20ppm. They even opened a new package of strips and got the same result again.
They gave me metal remover, which could take a couple of days to work and advised to just use the 2 tsp of bromine daily assuming the spa is also used daily.
Sorry this was so long, but I wanted to be clear about whats going on. I'd be grateful for any thoughts or suggestions?? So far this spa is not very
