I didn't read this entire thread (except the part of me inventing the internet, which, by the way, I did not. But I did invent blackworms
) I also noticed someone said you can kill algae bleenies if they eat mortar. Dam, I wish I knew that before I built practically all my rocks out of mortar and I have bleenies climbing up the walls they are so healthy. I also sometimes feed my fish Plaster of Paris, yes, don't ask.
I designed using motor for growing algae by accident. When I started my reef I collected all the rock myself in the tropics. Eventually I started giving that rock away and building my own out of mortar only because I liked it better and I could custom build it. Then I noticed if the tank was going through an algae cycle, it would only grow on the mortar rocks and not on the real rock so I figured there was something I the cement that algae was attracted to. I am sure it "likes" the rough surface, but real rock is also rough so it must be the minerals in the cement it likes. I don't really care what it is but that is why I have always used it to grow algae only where I want it to grow.
Now I have to go and look at my poor algae bleenies to see if they are eating any mortar. :facepalm:. I wonder how they distinguish that from the dolomite gravel I use.
so really hoping this helps a ton.
