I’m almost out of my current supplements, all for reef, I bought the 1000ml about four months ago and im on my last week of it. I wanna get a powder brand cause I heard it last longer, but I don’t know what are some good brands to get? I wanna an all in one if possible for calcium, Alk, phosphate, and all the other Elements if possible. If not then a good brand that makes them Separately, again I would rather have a powder version over liquid but I will tow either if they last a long time. Thanks for all the help.
