Looking to get back in the game

[pleasants9]

After 4 years, I'm ready to get back into the hobby. I've decided I want the 6'x2' foot print so mostly looking at 180 systems. I recently came across one that is running with some live rock, few large leather colonies and a single fish (clownfish). System has what looks to be a 40 long sump with an in sump return pump and large skimmer. He currently has three Mars aqua lights over the system. Asking$1200 for it all which I think is fair especially if he is willing to help move it to my house ( I don't have a truck).

My concerns are this.
1) its drilled on one end with the black overflow, two holes one for supply one for return. Most other systems seem to have two drilled overflow sections. Is that going to be detrimental to my success having the restricted volume of water turnover?

2) I see two major issues with the DT. Green bubble algae and aiptasia. It's not taking over but it is present on all rocks and parts of the tank. Since I plan to start out with just the clownfish for livestock, are my chances/options good for riding the tank of these pests or will I be battling it for as long as I keep the system alive?

Thanks!

No opinions? I am most curious about the 1 vs 2 overflows.

How big are the holes? If you can get a 1" drain, you'll be okay. You can always use BOTH holes for overflow and run return pipes up the side/back external to the tank.

If aiptasia is everywhere, and more important on the algae -- I'd break the tank down, wipe it with vinegar and start over. Cure some dry rock from BRS in the mean time and start off with a fresh installation.

yes, they are each 1" drains. I think that is what I will do, use both drilled holes for the drain and then just run a supply up and over from the other end. I am starting up a small QT tank for the fish and corals then I am debating on fully restarting the tank or just running it for a while with no lights and no added nutrients to starve out the unwanted growth.

Given a choice between old live rock covered with pests and fresh dry rock- I'd take the old stuff- particularly if you have the option to leave it dark for a nice long time.

And yes, I would use both for drains also.

Anyone know roughly what my gph flow limit is with a 1" gravity drain? Don't feel quite like doing the math...
