Thanks bang guy for such a detailed explanation! And yes, there are some corals in there, but you just can't see them! Haha! I don't have any leathers, however, so that's a good idea. I'll start with the magnesium plan and go from there, since leathers are a bit expensive and I don't really want to mess anything up with a Calcium Carbonate experiment unless I have to.
This "new" tank has been set up for about two months, but some of the rocks came from an old tank that had the same problem. Seems like in that tank, they did die out, but then they were only replaced by a nasty slime algae. We just decided to start over in hopes that none of it would come back. We picked all the rocks clean, and both the Neomeris and the bubble algae came back with a vengeance.
We were hoping an emerald crab would help the bubble algae, but I guess he can't eat fast enough. Or maybe he just cant' get to the bubble algae because of the dense Neomeris forest!
And yes, trigger40, it does look very cool. Especially if it was the only thing in the tank. But you can't see the cool corals and mushrooms unless you dig out the tall florescent grass bed! Maybe I should set up a Neomeris tank and call it a day.
Flower, interesting that it's for sale! I'll have to look into that before I "weed" my aquatic garden. Thanks!!
