herbie overflow

Hi, I have an Aquaforest 790 with an Aquaforest sump. Basically a 155 gallon display with internal overflow herbie drain. I'm running a Tunze osmolator ATO. I'm using a Sicce SDC 6 return pump. My basic problem is with level stability in the return chamber. I live in Virginia, and we...

I have an 8' tank with dual corner overflows. But unlike most reef-ready tanks, I have 3 holes in each ooverflow. I need this tank to be quiet at 1000-1200gph. Given my options am I better off with a dual Herbie setup or a BeanAnimal? Dual Herbie overflows seem like they would be a PITA to keep...

Upgrading my 100g to this 225g. It has 2 overflows one in each corner. Each overflow has 2, 1.75” holes drilled. So if drilled for a 1” bulkhead or 3/4 sch 80 bulkhead. I think I decided on herbie drain. 1.Should I keep the full siphon and emergency at 1” bulkhead? I didn't want to run pipes...

There's two valves I'd like to plumb horizontally. Can I achieve full syphon with a gate valve on a Herbie main drain, if the gate valve is plumbed horizontally? Will a Y-style check valve (pictured) still work properly, if plumbed horizontally? I believe this is also called a Wye Check Valve...

I am in the process of setting up a new 125g display tank with a three drain Herbie overflow from Modular Marine. I have my primary drain flowing to my fleece roller and the emergency drain dropping directly into my pump chamber with and air gap so I will hear audible splashing and see bubbles...

I'm in the process of setting up my first saltwater tank. It's a 60 Gal cube with a custom 20G High as a sump. I'm finally at the stage of leak testing my plumbing. However, I can't get it to maintain a consistent water level in the overflow box. I'm using a Herbie overflow and can't seem to...

I'm setting up a used 120 g tank with a single corner overflow. The overflow has two drilled holes (1" and 3/4"), I'm converting it to a herbie style drain and running an over the top return. My question is, will the 3/4" drain and 1" emergency drain be enough flow for the 120 gallon tank? I...

So I purchased the h2overflow and stealth box and finally got it set up using the herbie method with a small trickle of water going into the emergency overflow, I do not know what the issue is but it is pretty loud I got the tornado effect on my main line I think that’s causing the issue but I...

Hi You ALL, I have been reading, watching youtube vids, reading more, watching more videos, day and night, home and at work. Pretty much the last 3 months i have been all about saltwater fish tanks. At first i was looking at buying a 50 gallon tank bc i read that its the best beginner tank...

So here is the thing I am currently new and plumbing my first tank. I am doing a Herbie overflow because that seems to be what fits on a tank that has 2 bulkheads. Essentially I have a sump with 2 filter socks and outlets to get plumbed to those filter socks. What I am trying to do is maximize...

If you use a Herbie drain system in your overflow do trickle into the emergency standpipe or keep it dry? Why? I've read a lot of stuff that says to keep a slight trickle going down the emergency standpipe, but don't let it create a siphon. I'm trying to understand why we would even bother to...

I have a dual corner overflow, with a pair of 1" bulkheads in each overflow. I'm using an Abyzz A200 for return from my basement sump. My plan is to have relatively low turnover, 5ish X my 210G system volume. I read on GMAC reefs writeup on dual corner overflows that because of the capacity...

Alright so I need everyones' opinion here. I have a 120 gallon tank. I believe it is an Aqueon. It has two overflow boxes with the undersized holes drilled for 1 inch ABS bulkheads ;Rage. Currently I am running a single durso in each overflow box. I am building a new sump and when I install...

I have been running a 120 gallon reef-ready reef tank for the past 6 years. For all of this time I have been running with the drain kit that can be bought in addition to the tank. I have switched up the plumbing underneath the tank multiple times but it has always been one durso in each...
