I would try Premium Aquatics INC - live rock and aquarium supply or Aquarium supplies for your tropical fish tank, saltwater fish tank, saltwater aquarium fish, freshwater aquarium fish & reef aquarium. Aquarium filters, aquarium lighting, aquarium tanks, protein skimmers & more for your reef tank. I use and trust both of these sites. I agree with Otty about Elos, Salifert supposedly has figured their issues out but Elos are Lab grade test kits. Perhaps just as important to me is their ease of use, much easier to use & read than Salifert IMO. On average $10 more a peice than Salifert. I just dropped $125 on Elos Mg, Nitrate, Phosphate, and Ammonia kits at Marinedepot.
