thanks for the compliments.
as to diatoms not really anything major, ive got lots of flow most of my nuisence algae happens in the refuge.
The Rock was sold as gap island rock, Love it, its half the weight of figi or marshall rock due to the branchiness and it stacks like legos so it does not fall down. also makes coral placement easy so you dont have to use epoxy, just push the coral plug into a space and it stays. my Rock is just kinda placed here and there ive seen someothers make some awsome looking reefs when they take the time to stack this stuff good. i plan to do a better job when i upgrade tanks in the future.
