Brew, I am so glad you sometimes read my posts. Historically Mods or Staff members don't read what I write for fear I will say something so politically, religious, sexist, not PC or just to far out there to be in the public domain. It could happen because I am old but my friend Moses is older.
A fact: Did you now that Moses was the first one to download tablets from the cloud.
For instance, I used to mix clams and worms with plaster of Paris and feed it to my reef. Yes i did.
I also like to use bricks under my rocks or feed frozen bananas to moorish Idols. Maybe they think it's a sponge, but they eat it.
I started my tank by adding garden soil.
All those must have been better than tuffa rock we used to use Paul.
