when i first bought my branching bubble coral it was pure white, ive had it for 6months or so now and well lets just say its no longer white. over the months its turned some reddish brownish color on the bubbles though there is still some white left. can anyone tell me why its not white anymore? ive tried googleing it but no luck. is algae growing on it? need better water flow?. sugesstions please.
