Yo Coral Keeper, I am glad someone else besides me doesnt like using chemiclas and goes with a natural approach
I also have fighting conchs in each of my nanos and they seem to do the trick on the sandbed. i MEAN My sandbed is top notch looking. Superb white coloration all over
I know that fighting conch will have your sandbed cleaned off tha diatoms in no time. Goodluck
