I refilled my Sundance Altamar yesterday. I followed the Bromine system listed here to the tee. Everything went as I thought it would. I added the Metal Sequester, raised TA to 105 using Baking Soda, Adjusted PH using Spa Down (dry acid?) from a strong 8 to 7.5, added calcium booster to get to around 200, I used 2 ounces of sodium Bromide powder
(says 99% pure) followed by 8 Ounces of 6% regular Clorox. Bromine test showed 12.5. I let circulate for a few hours and the level dropped to 9. I dropped two bromine tabs in the compartment and I let my daughter and two grand kids soak a few hours later for about 45 minutes after the temp rose to about 98F. This was all yesterday starting in the AM (I drained tub the night before). Now just a few minutes ago, I checked the bromine and it is zero. I use a Taylor K2106 kit. No even a trace of pink shows up, even with an extra dipper of indicator powder. Question is did I do something wrong? And more importantly do I need to drain and refill? I just added 6 ounces more of 6% regular bleach and the tub is circulating. Tub holds right at 400 gallons. I am bummed. The two bromine tabs I put in yesterday are still mostly full size?
Please let me know what I need to do.
I just tested after adding the 6 Ounces of bleach and circulating for 20 minutes and the bromine level is at 8.5 ppm. Not sure if this helps at all. Still need to know If I need to drain and refill. I want to be sure I have a sanitized tub.
