Nice RBTA!! Great color. If you tape a picture of clownfish in an anemone to the side of the tank it will usually get the clowns to go in the nem. It sounds silly, but for me it has worked 100%.

If you have hair algae (or any other nuisance algae) growing in the tank and the phosphate and/or nitrate is/are undetectable that is because the algae is sucking the nutrients out of the water making it impossible to detect with your text kits. Also, ammonia should never be detectable after the initial cycle is over. Either you have a faulty test kit, or there is die-off in the tank. For a reef tank you should also be testing and dosing magnesium.

There is nothing wrong with the GFO reactor dumping into the refugium, unless your refugium is actually a macroalgae harvesting factory which would cause it to be inefficient.
