I have come to the conclusion that no one (including myself), really knows much about coralline algae. We see patterns but the more research I do, nothing makes sense when it comes to coralline. Until just the other day I thought coralline grew best in tanks with pristine water quality, until I saw one of the worst maintained reef tanks ever at my local Petco. It was covered wall to wall with coralline and hair algae as well. I asked for a small water sample and took it home and tested it. The results scared me (very high phosphates and nitrates, 180 on calcium, and 5 on the kh
). I then went and tested one of my coral only tanks, which always has perfect conditions, but basically little to no coralline at 4 years of existence. A little on the powerheads but that's it. That doesn't make sense, sps
grow just fine but not coralline. My latest "guess" is that coralline (or some types of coralline) feed on something that's left over in uneaten fish food. In my tanks it seems, the more I feed (within reason) the more coralline grows. This goes hand in hand with the petco tank as well, and with my coral tank that never sees growth or food other than giant mysis for Orange cups. I've read people's posts where it's stated coralline will for sure eventually grow no matter what, but in one of my best maintained tanks it hasn't after nearly 4 years. But I my 1 year old tank, I can't get rid of it. And, yes I tried seeding the coral tank with many different kinds. Can't seem to figure it out. But to your question, is it possible that the coralline growth pattern coincides with periods of heavier feeding.
