End overflows !

Opinions needed on efficiency of end over flow boxes please. Also internal vs external and why ? Thanks

 

All depends on size of tank and volume of water.
In a 200 plus tank, drilling internal drains at 2 inches could cause stress to the bottom panel. The room for external is another thing to keep in mind. Other than that, that's all I know bout that... um huh

 

I have no idea, but I'm fallowing.

 

Your tank you mean. ? Or following thread. ? Lol.

 

It's going to be slightly bigger than our 1000lt. Will be about 1200lt. Side will be against wall with tank dividing a room tank will be visible from both sides ! Just I am used to 5.5 foot overflow and wondering if 3 foot with more water volume will have enough turnover in the sump. ? I assume power heads will all be at one end too. ? How does this go for movement. ? Dies anyone have one of these that can help. ?

 

Water goes in water goes out. Same concept, different design.

 

Understand that. But surely more water goes over a 5 foot weir than a 21/2 foot weir ?

 

I would not see an issue if your running less that 6000gph.

 

The thread.

 

If all powerheads are at one end. (Overflow end) how do u create current coming back to overflow?

 

You could have either one with the same size drain hole and they'd flow the same amount of water.

 

Thanks rob. I get that now. ! Any clever answer to powerhead question. !

 

OK, put them a little lower in the tank to allow the upper water to flow back to the overflow.

 

Thanks. Have been reading a bit about the peninsular and your spot on. Thanks a lot. Just panicking that this tank will be as easy & stable as the current one This one has been so darn easy compared to some & just trying to replicate ( we hope)

 

The one thing you have to remember is that waste products are lighter than saltwater so they're going to be on top. You want to let them make their way to the skimmer or whatever filtration you're using.

 

Have just pre-ordered the Maxspect Gyer - hoping it does what is claims, says it easily does an 8-10 foot tank ! lol
