So, I've been doing freshwater tanks for over 30 years. Picked up this 125g tank for $300 (with everything included) and decided I'm now old enough to start my journey into saltwater. Problem is that I'm totally clueless. I will be moving at a snail's pace as I learn but wondered if someone could tell me what I have here and if what I have is adequate for the tank. Here's the pics:
Any help is greatly appreciated.
