salt brand and testing kit

I am wondering what brand salt you used and what kind of testing kit do you recommend

 

For reefs I'm a fan of the new Brightwell salt. Before that I used Tropic Marin. Both are very good. What type of test are you asking about? Chemical tests or salt content measuring. For salt I use a refractometer.

 

I use Seachem Reef Salt. I use a refractometer to test the salt mix. I use Seachem Calcium and Magnesium test kits. The Mag kit has an alkalinity test also. I am using Aquarium Pharmaceuticals test kits for nitrate, nitrite, ammonia and phosphate.

 

I have just switched over to Tropic Marin's new Bio Actif Salt in my smaller 60 gallon mixed SPS LPS reef and have kept using their standard Tropic Marin Salt in my main 90 gallon reef to compare what benefits the new salt has. I have always been happy with Tropic Marin's products and I am looking forward to seeing the results from their new salt. From the literature I have read, the Bio Actif Salt sounds like it should produce some great results.

 

Anybody use reef crystal? Im just trying to research on wich one to use
