Advice Needed. 14 Gallon Biocube.

[biocube14]

2 more updated pics. Added a few more corals since the last update. Added a hammer, frogspawn, candy cane and bubble.

So far so good. I hope I'll be able to keep these alive. Any suggestions on placement would be great! I read online that they like mid to low fow so i directed my powerhead to the left wall of the tank and the return is now pointed to the top, front center of the tank.

Also read that people had success without adding additives to the tank. Any tips for these corals would be great!
