The entire tank has been up and running since March 2006, I added quite a bit of coral in June 2006 including the ora tort. I like to order from Dr's, reef science, atlantis, upscales, most of the frags came from a local store Allquatics in Trenton NJ. Most of the corals are 2 years old. I originally purchased fast growers, monti caps, milli, bird nest. They really filled in nicely and quickly.
It seems as the corals begin to fill in I want less and less rock in the main tank. I would eventually like to remove quite a bit or rock and let the corals become massive. They grow quicker than I thought.
I feel my corals do well for several reasons:
1. There is 6 400 watt halide lights and 4 160wattt vho. I have moved colorful corals to lower levels and they fade in color quickly. I run them with dependable m59 magnetic ballasts. They would compare to the brightness of a 250 watt on ice cap ballast with reflectors, probably slightly brighter. I have a mix of bulbs 20k, 14k, 10k and 6.5k. I like the look of 20 k the best but I think 10k really grows and brings out pigments the best. Halides for 7 hrs and actinic for 14 hrs.
1b. A lot of water flow, 50 x , visible water movement in tank and surface.
2. The ever controversial refugium, for me I added it about 1 yr into the tank and it really started to flourish at this point. The refugium is a simple 55 gal tank with home depot florescent light day light bulbs on 24/7. Two bags of sand one play sand and one crushed coral super fine on bottom a power head to move water and a power head to feed the refug.
3. Change 30 gals a week with pure ro/di 00.00 water, Kalk auto top off.
4. A filter sock on a dart intake changed 2x a week and a lot of live rock in tank and sump with noticeable sponge growth on them.
5. Have good carbon aquarium pharmaceuticals brand and bulk reef supply brand phos remover, I place it in a bag and run it for about a week a month, in between I throw it in the new water tank.
I do have a excellent bubble king skimmer but it is turned off quite a bit more than on. I think this really is a big factor, clean water is a must but there is a lot of good food being removed with a skimmer. I try to have nitrates with salifert, looking sideways on the test vial, very slightly pink. Phosphate super low, really do not test much but have deltec kit.
I do add a carbon source like azno3, zeo food or vodka 2 to 3 times a week. Keeps nitrates low.
Finally ( there hope for reefers on a budget) I use 2 part, with my size tank I just add 1/2 cup of baking soda a day, 1/2 cup of mag flakes and check ca on weekend and add about 2 cups.
SUM UP: GOOD LIGHT, REFUGIUM, 2 PART PLUS MG, SKIMMER NOT ON A LOT, SOME CARBON SOURCE, WEEKLY WATER CHANGE. WORKS FOR ME.
FYI I DO HAVE A 2 CHAMBER CA REACTOR I DECIDED TO REMOVE FROM THE SYSTEM. My ph is better now 8.3 vs 7.9 and I had to add 2 part anyway, I also have a kalk stirrer off line and opted to go with 30 gal Rubbermaid with kalk water on a auto top switch ATO brand. I also have a chiller still in its shrink wrap, the filter is in the basement where the ac is in the summer and heater in the winter.
Sounds like the kiss principle.
