Hey, i recently bought a few corals to add to a pretty new CADE 300 litre aquarium. They are all doing great but I've decided to do dosing instead of water changes. I took my baseline readings for a few days and figured out that I lose about 0.3 dkh and 10ppm of calcium per day. So I dosed 15ml of reef foundations A and B each day and got consistent readings. However, I noticed my frogspawn was completely closed up. I have a merulina coral which is much more difficult and picky but that one is doing great. I stopped dosing for a couple of days and the frogspawn is open and fluffy again. What's going on?
