Localized RTN?

[Ruth]

Christy I am having a real stuggle lately with my SPS as well but I am certain it is because of heat issues. I really really have to get a chiller particularly for my acrylic tank. Even with fans running full blast and looking really ghetto I am still having issues and loosing a few frags and colonies that had been doing well.
With that said flow can make a difference over time and if everything else is unchanged I would chalk it up to flow.
