Another Time Lapse of my saltwater tank. The camera was set to 5 second intervals. This video shows how much macro fauna there is on your mature live rock. Please excuse the cloudiness of the water since I recently added extra sand and it has not cleared up completely. Also there is a excess of micro bubbles due to the HOB skimmer breaking in again. (I do not keep it running since it heats up the water way too fast and it is designed for a 70 gallon tank, just needed the extra filtration due to the new nitro cycle because of the added sand) This is a BioCube 14 gallon tank that has been modified and improved.
