 Re: algae info
Yes Cynobacteria can form a reddish or greenish mat either on the substrate or on your L/R. It can even move onto the coral. Water movement is important also. You want to have a water turnover rate of at least 6 times the volume of water/Hr. So if you have a 55 gal. tank your turnover should be 55 X 6=330GPH. Also you want to take into account the vertical pumping action ie: {head}. The general rule is to add about 20%, in this case 20% of 330=66. Adding that to the original 330, you get 396 or approx. 400 GPH. That is the size main pump you would need.
