This will be the last update of this tank before it's birthday in 3 weeks.
Many of the rocks have a very short red turf algae on them that comes from the Sound and I see it as a good sign. If I see no growth, no algae, no reds or greens I know something is wrong. Multitudes of pods, worms, brittle stars and other tiny indescript creatures is a very good sign and a tank with spotless clean rocks is not very healthy.
Some algae is a good sign, not a lettuce farm but some spots here and there.
This slight algae sometimes gets more or less depending somewhat on the animals I keep but more so on the cycles the tank experiences. Sometimes the algae gets long and I will see some hair algae but these short cycles now only last a couple of weeks every few years.
This is the first time I remember that the SPS, LPS and leathers are all healthy and growing at the same time, usually one type prevails.
I have not seen any type of paracite or disease in decades and it seems the fish will live forever, or as long as me anyway as I am old. Maybe the tank is finally cycled. In 3 weeks the tank will be 40 years old, maybe I will start a new thread.
