I have 7 new coral and they all seem to be doing good. I had to try different positioning for the corals to make sure they don't have to little or too much light and also be sure that they have just the right water flow. I've been feeding the acan every few days which has really brought out some growth and color. My clown has adjusted well and swims happily around the tank looking for food in the water column. I've been supplementing it's diet with reef flakes and bloodworms (which he really likes). I use the H.O.B. filter for it's carbon cartridges which I change on a regular basis. I know everyone says they are nitrate factories, but I've yet to encounter a problem with it. The filter also seems to add some extra flow and oxygen to the water which is also a bonus. Nitrates and phosphates are at zero and nuisance algae has slowed down considerably since I've been dosing kalkwasser and maintaining a 8.4 PH. Every day I notice new things growing out of my live rock. Feather duster worms, coralline algae, and other strange creatures which I've yet to identify. My reef tank has been thriving and I've been very pleased with how my patience has paid off. I've ordered some cyclopseeze for my corals and another timer so I can run both sets of lights simultaneously. They should be arriving tomorrow or Friday.
