I bought this pool test kit before discovering this forum:
5 Way Swimming Pool Spa Pool Above Water Chemical Test Kit | eBay
Is it good enough, or do I need to buy something else? If something else, which one?
Is this #1 seller on Amazon good?
Amazon.com : Poolmaster 22260 5-Way Test Kit with Case - Basic Collection : Swimming Pool Liquid Test Kits : Patio, Lawn Garden
Outdoor concrete pool, unsure of size, but about 5' deep at deep end.
