Precision Marine is having a workshop on calcium reactors at 2:30 pm on Saturday. We have many customers with questions on how to properly set-up calcium reactors and fine tune them. This would be a great opportunity to speak, learn, and get answers from the experts. The workshop will be followed by a super sale on the PM Calcium reactors. The RFca4 reactors will be further discounted to $319.99, that's almost $100 in savings off regular price!
