that Fish Guy
Frag Swap Crusader!
An sps retailer and only supplier of Tropic Marin products near my house advocates Regular Tropic Marin over the Pro.
He says the Regular salt has a lower alk than the pro... Anyone has experience with both to comment on this claim?
The Pro is Pretty Low in Alk (8 to 8.5)
I have never tested the Regular TM.
What does your Retailer Keep their Alkalinity at?
