What is killing my brown grasilaria? Allelopathy, me thinks.
Suspects include the fern caulerpa and ulva, both of whom have grown a lot lately. Also, the turtle weed is a known allele-combatant.
It's kind of weird for me, because I want it gone, but now that it's going, I wonder about the cause, and could it kill the plants I want to keep? Mind you I'm not trying to save it either. But now, I'd like to replace it with some other ground cover between the grasses. I want to provide cover for the little guys, like pods and micro stars.
Another new plant popped up recently that I need to decide on keeping or not. I need to decide soon because it can be invasive. Its Dictoya, which I'd automatically get rid of, but it looks to be the kind with some blue iridescence. So it could be pretty. Hence my quandary.
I've finally succeeded in getting some of the petticoat algae growing on the back wall. They're tiny but it's a start. This could look very cool up there. Another candidate for the wall.
With the weather cooling down up here at 7500 ft, I think I'm starting to keep the tank water temp below 80º. Maybe the codium, which has died back over the summer, can come back. I'll keep an eye on it. I think there are two whole plants left. I do hope it rallies. It looks great among the grasses.
Oh, and I think I will have some new manatee grass plants soon. I'm really looking forward to filling in my little meadow. The ones I have left are doing well, including the ones I transplanted. But there is a big empty space I'd like to get filled.
Coming up on ten months. Still aways off from the vision for this aquarium. I'm moving in the right direction!
