The test plugs are done and soaking in fresh water. One has iron and one is just cement. In a few days I will put them in my algae trough. I am really hoping the iron sintered one grows more algae, if it does I will line the entire bottom of the trough in the stuff in the hope that it will grow more algae. I think it will. Of course it may also grow more algae in the entire tank and that would not be what I am going for but you have to experiment to learn these things.
The tank is running beautifully with nothing receeding or dying. All the SPS seem to be growing and the LPS are all doing great from being fed clams and oil soaked pellets every day. I re designed my live worm keeper so I don't have tobuy worms very often, they don't get caught in the powerhead and seem to be breeding but I am not sure about that.
Have a great Christmas which is also my birthday.
Take care
Paul
