I have been using Reef Crystal's and like it so far, it mixes great too. I accidentally ordered the regular instant ocean salt. Is it safe to switch over without causing any problems? I have around 50 gallons water volume and only do water a change of around 6 gallons monthly. Tank temp 79 to 80°, ammonia, nitrites, nitrates, phosphates 0, ph 8.3. Alkalinity is a little low 7.5 so I was going to dose a little baking soda slowly to a high flow area. Calcium and magnesium test very high. I was going to return the IO and pick up reef crystals but was wondering if I should just try the IO since my calcium and magnesium is so high using Reed crystals. Calcium is 550 magnesium is off the chart. Going to double check the magnesium test but my calcium usually tests high. Would a low alkalinity affect those tests? Appreciate any helpful information from you experienced guys that are always so helpful.
