first, thanks, this site is really useful. Problem: inground circa 1984 sylvan 25,000 gal pool with 5 yr old sand filter just emptied, powerwashed and re-painted it. filling it now. I would like to try the BBB method but am wondering:
1. Can get a testing kit locally (Walmart, pool store) or do I need to send away for your recommendations?
2. Where can I get BB in bulk?
3. Any other recommendations?
Thanks in advance
