Bought the Seawater Alk and Marine Calcium testing kits late last year and only used both twice. Just not a fan honestly and prefer my other testing kits.
Alk (dKH) kits reagents expire 10/22 but everything else is in like new condition -$40
Calcium (ppm) kits reagents 01/24 and is also in like new condition, 23/25 test remaining -$45
FCFS, no trades. Paypal, Venmo, Cashapp to hold is fine.
