my params are, cal 440ppm, alk 7.0, mag 1500, ive added about 5 so far and all is well, just didnt want to rush into it, also i wanted to know if supplementation was necessary if continuing regular water changes weekly. i use red sea coral pro salt, i just cant get my head around how to successfully supplement the red sea reef care range no matter how many times i read up on it!!!!
