I'm using Oceanic for the calcium and higher mag & potassium. I dose baking soda in my topoff to make up the low alk.
When I use up my last 2 buckets I'm switching to OceanPure pro based on several reccomendations from other SPS reefers.
i have been using the scripps water for year. a few months back i went to tropic marine and even dabbbled with the pro. i have had great results so far but i have now switched again to the DandD salt. to early to rave about this i do know the elements that i am looking for a higher. i will know the true visual results in about 2 more months. all is good so far though
