Good morning. My question is, my corals and fish are looking great. Hammers are growing multiple heads, torches same, zoas are growing ( slower than I want but growing) but I recently tested my water and I feel as my levels might be to high in mag and calcium and might want to reduce it. I am afraid that if I start doing water change every 2 weeks I might mess to mich with the corals and all and maybe take a hit and everything will start going bad. I don't do water change that often or at all I had the tank for over a year and a half now and can't really remember a water change. Again just tested my water 2 days ago. So what do you guys think? Should I start doing water change every 2 weeks like maybe 10 to 15% or is there another way to reduce may calcium and mag? My corals aren't consuming it that much. My tank is 125 gallons.
