Hi Jimmy and thanks.

I guess you are right. But I'm worried of the long term effects ( than
2 or 3 years.) Plus, could it me that I have not yet introduced a coral
that may be harmed by this type of Lux?

Regards

Richard

My tank is about 1 1/2 years old, with a 175 W MH pendant, and I've had
no problems with heat or any other matter, except when I allowed the
first bulb to get old--this caused my bubble coral to shrivel up


Can anyone offer their opinion on the matter.


So just ask yourself -- Which should you be listening to? Dr Goldstein who
knows nothing about your tank, or your corals?
