i was having a problem keeping my calcium up especially with weekly wc's. i use instant ocean but i was thinking of switching to reef crystals. my question is which is easier and cheaper. since reef crystals has more of what i need in the ca, alk, and mag areas. should i just add turbo calcium and baking soda to my new water or switch to reef crystals which is about 50 bux here compared to 34 for the 200 gal box of IO salt
