Salinity .026All good advice so far. You have only been in this hobby for six months, slow down. I have been reefing for 6-7 years and still have some setbacks, but I won't give up. If your fish are doing fine now just take care of them for a few months, get your algae under control, let the coraline algae increase throughout your tank. If you can give us all the water parameters you are testing, you may think it is all good but you may be missing something, happens to me still.
