Api Saltwater Ammonia Color Card - Free

[Gvilleguy]

I bought an API ammonia liquid test kit (the two bottle deal) - and it came with both a freshwater and saltwater color card. I don't need the saltwater card. So if you have an old card that is getting warped and bent - ping me and I'll mail the saltwater card to you for free. Don't want to just throw it away.

Thanks,
Greenville Guy
