Ghost over flow options?

[Jvesche20]

I’m currently building a 180 gallon tank. I’m looking for a good ghost overflow for a sps tank. I’m looking for something to drill into the tank. This is what I was told to use by one user a few months back. But I wanna see if there others out there.

32" Overflow Kit with 1.5" Drains

This is our standard 32" slimline overflow kit. The weir openings are 0.5" tall, with a total distance from the top of the box only 1". The external box utilizes 1.5" drains for increased flow capability. If you are flowing over 1500 GPH through your sump, this is the system we recommend. The...

I have 2 of the 1600 gph on my 260 gallon and I like them, they are easy to set up and very quiet.

Following. Was thinking about EMS one as well. I like their design more than MM, Synergy Reef and Shadow

I went with the 2 1600 gph units so I would have 1 inch piping

What does it look like from the front of the tank?

I’m thinking about doing 1 large one. I ended up getting a 220 gallon tank. Would you recommend getting one large one or 2 smaller ones?

I will take a couple pics later today, I painted the back and sides of the tank black and the overflows are barely noticeable.
My tank is 7 ft long and I was worried about not getting good surface skimming at the ends of the tank, plus I thought 2 smaller ones would be quieter than 1 large one, I have no regrets.

Every time I look at their store it is out of stock.

There have been a number of threads over the last couple of years on these overflows - suggest you read them. Three years ago, when I was looking for an overflow for a large tank, I looked at all of the available options. One of my key design principles was for a single, larger overflow. This dropped a number of the more ‘common’ vendors off the list. I also wanted an overflow where the external box was at the same height as the internal box - as you approach the max flow of an overflow, those with dropped rear boxes are almost impossible to keep quiet. This dropped other vendors off my list. I also wanted some customization. More drops!

I ended up with two vendors left - modular marine and EMS. Ultimately I went with MM, though I have also worked with EMS and would not hesitate to recommend either. I have a slight preference for MM as I like the fit and finish a bit better.

I bought the 32” 3,600 GPH model with a full length external box. It works exactly as advertised on my 450.

No matter large or small, if the plumbing is 1 1/2 your going to get 1500gph. If you want more just add two.

This is because the only way to get the Ghost overflow from Reef Savvy is to order a custom tank from either them, or Miracles Aquariums. You can not order them separately.

As for low profile external overflows (Ghost overflow is not the type of overflow it's a particular brands name, little pet peeve of mine), Exotic Marine Systems, Modular Marine or Fiji Cube are all solid options.

+1 on the modular marine overflows. I like the fact that the outside box is at the same height as the inside box.

Fiji cube also makes similar overflows. I would go with whatever is available at the time.

This is your best option, by far.

Go for it, you won’t regret it
