Seeking help
I am fighting a number of issues with my reef tank. It all started when I decided to remove a very large coral and frag it, keep the frags and pass the rest to my LFS. After that event I developed what best can be described as a build up of a white fiber coating the glass and any branching coral. Then I noticed that my alkalinity was rising despite me not adding any alkalinity solution. I had to leave town on business so trouble shooting from afar is a bit of a challenging. Finally I noticed that when I turned off all Dosing (Alk, Mag, Ca) the alkalinity has stopped rising and is slowly falling. I am at a total loss of what’s going on.
The tank is a 115 gallon tank 6 years old. Been basically very stable till now. As of today the reading are 12.50 alk ( it maxed at 13.00), 415 cal and 1330 Mag. I plan to measure phosphate and the other parameters when I get home as I suspect removal of coral ( and the live rock was temporarily removed) upset the balance.
Normal maintenance is 10 percent water change per week.
Thanks in advance for advise
