Reefing newb
So I've had my tank up for about 6 months now (14 gallon biocube). When I first started testing my alkalinity it was around 12, however I've watched it slowly drop and for the past, oh 2 months probably it's been sitting at 6. Everything else is fine, my pH is about 8.3, my calcium is at 440, but my alkalinity just stays at 6. I do probably a 30% water change 1x a week. I used to make my own saltwater using RO water and oceanic salt, but the past few water changes I've used sea water to see if that will make a difference (it hasn't). I do have some corals and they're all doing really well, from what I can tell and the tank seems to be healthy. I'm just a little concerned. Should I be? I picked up some Reef Builder by Seachem at the LFS a couple days ago, but I'm a little afraid to dose my tank with anything, especially since it's so small I don't want to accidentally overdose. Suggestions? :lamp5:
