The star with the best survuval rate in the home aquaria is the Linckia Multiflora.
I tried to add an image, but this BB won't allow prentheses within UBB code.
However, I have included a hyperlink to a google page with numerous references to above mentioned echinoderm: Linckia Multiflora
In a nutshell: Mustard gas
Mixing a chlorinated product with an acid produces mustard gas. It's the first thing I train employees on when they start working sanitation for me.
Granted my chemicals are quite a bit stronger and the health hazard posed is far greater. However . . .
It may be hard to balance the system.
First fill the aquarium completely full with water.
Second fill the sump until the water level is just below the working range of the mag pump.
Start the overflow and let it drain the tank as low as it will go to ensure that the sump will not overflow...
Just start over with the same sand. You're going to have to go through the whole cycling process again. If you have dead bodies in the tank, leave'em. They're going to be a good source of nutrient for the nitrogen cycle to get restarted.
Leave the lights off for the first couple of weeks...
PNW anemone can be some of the most beautiful. When I took Invert Zoo. in college we used a cold tank because specimens are cheaper and are found locally. Imagine a large red anemone with white spots like a blood shrimp. Oustanding!
Actually, its a rigid line that's supposed to be moved up and down to adjust the water level in the back box, but it's the same principle. Never got it to work right . . .
One should always keep in mind the fact that as the tank matures, and corraline algae begins to form, LR loses much of its value in nitrate conversion as the multiple small tunnels in the rock with a waterflow low enough to support anaerobic bacteria are grown over and sealed.

Let's be realistic here. Algaes are very simple plants. They do not need a dark period. period.
There is always some discussion about a plant's light cycle versus it's dark cycle. There are two cycles in a photosynthetic arganism the photosynthetic cycle and the respiration cycle...
