I switched from Tropic Marin Pro to Aquavitro salinty.. I am at the end of my second bucket and I love it.. Shipwrecked was correct.... With the TMP I had to dose for everything and I dont dose at all with the Aquavitro Salinity now...It was a PITA to find but located a store that can get the aquavitro in a day or 2 for $87.00
This analysis is a few years old but could not find a more recent one.

Update: Mike we posted the same link almost at the same time. Who says great minds don't think a like.
Since I only have softies and fish right I now I decided to try the Red Sea. I am already dosing and the deal was good IMO, 28lbs for $11.
Thanks everyone
Am I the only one here using Oceanic?? I never hear of anybody. I have been using it for years and do not add anything and 90% of my sps have great growth....Some coloring could be better, but overall I was pleased with my tank untill the hurricane loss
