I am no expert I will start by saying that but all the reefers I have known over the years the ones who chased a specific number always seemed to have problems. As long as you are in a acceptable range I would say you are good. If you don’t have a lot of coral in your system I see no need to complicate thing and dose anything as long as you are doing water changes. Monthly or bi monthly changes should maintain most systems. These little slices of oceans we keep in our houses are miniature ecosystems they a lot of time are trying to fix what you are adding to the tank which off sets numbers. Then you change and it changes and never becomes stable. By no means am I saying don’t dose I am just saying if there is no need except to try and get a different number, WHY? I base almost everything off the way a coral or corals look. Like your toad stools not looking hot do a water change and wait and see for two weeks still no change do a water change again and wait and see. Bet it starts to perk up. Water changes are your best friend unless you are Ty (he is a freak of nature) and another thing is out of 100 members I bet none of them see eye to eye on everything. Find someone who has a tank like yours and you can see what they do actually works and then reach out to them for advice. If you try and do what everyone says on here they will conflict and it will cause you problems Sent from my iPhone using Tapatalk
