cube Tank has been up for about 4 months, no problems. Parameters good, lots of crabs and stuff, but only two little fish ( firefish and goby).
I had added some Calcareous alge several weeks ago to feed some of the crabs and snails. It was doing fairly well, although got snacked upon occaisionally. Yesterday, it started turning white. By mid day it was all white. Today, white and brown and the entire tank is very cloudy and the zoos are all closed up.
I am in the process of a water change, got to wait to get it up to temp. And I put the protein skimmer on high.
What happened and what now? I took out the macro alge and threw it away. I had also put in some small nori that was pretty much eaten. Other than that, nothing new. No new foods, no new quantities of food, no change in cycle.
