Ordering a 130x30x30, closed loop or not?

[Easttuth]

I've never owned a closed loop system but have read up on them and like the idea. Benefits of the system seem to be less cost and cleaner look. Benefit to powerheads are flexibility moving forward. Powerheads are much more costly and closed loop creates substantially more plumbing if doing many outlets.

Am I understsnding this correct? Any reason why the tank length would play a roll here at 130" long?

On a tank that size I would do it. Going to need a lot of flow and a closed loop would help you tremendously.

Don't underestimate plumbing costs. Quality union ball valves are pricey and will add up.

I'm not a fan of having holes all over a tank. Especially the bottom. Makes me nervous.

You can move a powerhead if needed. Can't move a hole.

I got an automated 3 ways valve if you interested, but take it from someone who used close loop since 2000, you are better off with low power propeller type PH.

The problem with close loop is that the intake is a beast. You really need to defuse the flow though this or else animals can get suck in there. If you sue a loop that is 2000 gph then the intake got to be well screen and big. There goes the attractiveness of low profile. You cannot put the intake in the overflow box because it will suck in air. My close loop (back in 2002) was 4500 gph and I defuse the intake by use perforated 2 inches tube and run it along the outer of the overflow box.

Today with the propeller type PH, you much better off use these low profile PH.

Still if you want close loop I can sell you the 3 ways automated Hayward vales that will be perfect to use to created waves with a close loop. In perfect working order

The tank that I used the close loop in was the feature tank of the Advance Aquarist Jan 2002, the very first issue

I have always been a fan of the closed loop system. I currently have a tank that uses one now and I am incorporating a CL system in my new in wall build.

I suppose it depends a little on what kind of tank you are going for (FOWLR, SPS, etc.). I just don't think you can get the kind of flow you will need from a closed loop unless you go with a really huge pump; and even then you really don't get the same broad flow. And then the 'savings' may well be less than you think (and you'll use a lot more electricity). I've used both, on large tanks, and am firmly in the propeller pump camp.
