I've read quite a few negative reviews of this fixture on the internet. Most of these reviews, however, were compiled about 3-4 years ago, and I can personally attest to the fact that Odyssea fixtures have greatly improved as well as their bulbs. I've had the fixture about a month on my 90 gallon and I'm impressed with the results. My amazon swords and assorted other plants are growing quite nicely and the fixture does not really get that hot compared to my LED fixture on my 10 gallon nano-reef. So yeah, if your looking for economical T5HO fixtures, Odyssea should do you just fine.
