I want to keep it all!!
I'm only partially kidding...at this stage in the game, I am still in the dark about what livestock we may decide to keep. I don't know much about corals, sponges, or anemonies because I've never kept them. I've had saltwater *fish* for around 18 years, on and off, but never learned about reefkeeping because I thought it would be too difficult. My husband is the one who lit this fire under me, and he's only been into fishkeeping since last year when we set up the 125.
I do know that I don't want to be limited on what I can keep because my setup wasn't adequate enough. Right now the only thing that I know I want for sure, oddly enough, is a clam!
The wavemaker is truly a great idea, however, don't you need to have those mounted above the tank? The place where we will be putting the tank has pretty limited options. Since it is so big and will easily weigh over a ton when full, it will have to go downstairs in the living room because there is no basement, and will therefore sit on a floor with a concrete foundation under it. The way the room is set up, it doesn't have a place where we can mount something above or behind the tank.
I think that we may go the way some members have advised....closed loop with separate plumbing to the sump. Now, if we install a horizontal skimmer box in the back of the tank, what happens if the water level drops too low due to evaporation (I won't be able to have an auto top-off right away), say if we go out of town or something? Won't that spell disaster because the water flow to the sump will stop? I'm not even sure this scenario could happen, but my mind is weighing all of the possibilites!
Yes, it was supposedly drilled for a closed loop system.
