Day 29, Jun 25, 2011

Coralline algae is starting to develop on every rock. The coralline is desirable.  In addition to looking good, I want it to cover the rocks instead green hair algae and red slime algae. Good water quality is key to algae control. High pH, no ammonia, no nitrite, zero or near zero nitrates. Reverse osmosis water prevents additional phoshorus and nitrates. High quality salt replenished micro-nutrients. I started adding Kalkwasser to the freshwater top-off. This boosts the pH and adds calcium. I am running both lights for 8 hours and will gradually increase it to 10-12 hours a day.

 A sixth Zoanthid button is budding out in the lower left corner.  It should open in a few days.

Blurry, but I know someone who can teach me how to take better pictures.

I am hoping these single yellow polyps adhere to some grains of sand so I can superglue them to a piece of rock.

Aiptasia Anemone - This is a pest and will need to be removed from the tank.

Tube worms are starting to come out of the rocks and sand.

Days 15 - 18, June 2011

It has been 15 days and my ammonia and nitrate tests have not detected even a tiny increase. This is most likely because the rock was well cured and did not have any die off in the new tank.  I decided to take a risk and add some livestock without being sure the tank cycled. I started my cleanup crew with 2 Astrea snails and 2 Blue Legged Hermit Crabs. In one day the crabs ate all the undesirable brown algae off the rock in back left. With the algae in check, I can slowly start to increase the lighting.

Zoanthid buttons starting to open up.

This tiny piece of rock was in the back corner of a tank at my local reef store. I noticed seven polyps on it and they were happy to make a good deal.

These polyps are tiny and are stretching for the light.

A close-up of the long thin polyps on the leather coral.  They grab plankton from the water for food, but most of their nutrients come from zooxanthellae algae that live under the skin of the animal.  Corals have a symbiotic relationship with this algae.  The algae lives off the sun and the coral lives off the algae.  The light I am providing for the corals is 50% 10,000k natural daylight and 50% actinic blue.  The blue light replicates the spectrum that the corals get when they are 10-15 feet below the ocean surface.

Day 2, May 29, 2011

I like the rock arrangement, but it is pretty bare in the tank.  Not much trace of life except for one rock with a lone Ultra Green Palythoa on it and another with an aiptasia anemone on it.  Even though the anemone is cute, I will eventually have to remove it because it is agressive and reproduces fast.  The only other signs of life were two bristle worms and a few small amphipods.
