overflow

Hey guys! For sale is a brand new in box Synergy Shadow overflow, I just don't need it. The only very minor issue is that I had this stored in my garage, I left the garage door open one day, and a little bit of rain got on the box. So the box got just a little discolored, but the box is still...

Hey everyone, so I’m going to be drilling holes in my 75 gallon tank for both overflows and returns. I’m going to be using an Eclipse L from Eshopps, and they provided the bit as well as a guide so I’m good there, but I’m confused as to how large I should make a hole for my return. The overflow...

SO i just made a post about a 300GPH overflow and if it was enough now I want to know if a 1200GPH is enough for a 80 gallon system. I am just worried it will be too much turn over but I have the opportunity to get a very good deal on a 1200GPH

Hello everyone, I currently have a 40B FOWLR tank that’s up and running and wanted to add a sump 20L for better filtration and water quality. I have no issues with my current HOB Fluval 70 and skimmer + UV, but wanted to free up space on the back and hide the equipment. I’m currently debating...

Hi guys! In the past few days, I've been working on plumbing a new reef tank I bought, I chose the Herbie overflow method, so I placed my main drain pipe about 5 inches below the emergency one, so the problem is that my new tank comes with an internal overflow box that has water lintels above...

Hello everyone, I just picked up a 50 gallon lowboy tank and I am planning on drilling it and putting one of these Fiji cube overflow boxes 600 gallon per hour. The tank will be 50 gallons and I’m planning on getting a 40 gallon sump if that falls through odds are, I will be going with a 20...

Hi all, I’ve been setting up a 120g system over the past couple of months and finally got it wet yesterday. Overall a good test, no leaks and custom sump setup is working as planned. The one issue I’m having is with my water level being high in the display. Naturally I expected the water...

Would you always go for a predrilled tank? Or prefer the standard? What reason? The standard version plus a hob overflow cost nearly the same as this seapora drilled.

I’m looking to buy a ghost overflow for my 60gallon reef, preferably a synergy shadow overflow but am willing to look at others if they are quiet and work well

I’m looking at this used tank setup and I’ve been out of the hobby for some time so forgive me if this is a stupid question. This is a Truvue 50 acrylic. As you can it has a sump setup and a protein skimmer. The pump is in the sump. The price is $400 which seems good for everything but I don’t...

I have an Innovative Marine 50 gal EXT tank with a herbie style overflow and ive been having a lot of trouble with my overflow fluctuating. I have a trigger crystal cube 18 sump and had originally for a couple of months used a Sicce Syncra 3.0 for my return but had been having issues with my...

Hey all, I’ve been working on setting up my 135 and I’m well into the process. I’m running two canister filters on the main 135 reef so I do not have a sump. I want to plumb a 15 gallon column tank into the main display, but I don’t want a HOB overflow or to drill the tank. My idea is to run a...

Hi, I’ve just bought my own display tank as I fancied doing my own setup, stand, sump and plumbing etc myself. Im stuck between which overflow to buy between the 2 types attached. The shorter box would be good because it takes less space, however it means the plumbing is at the back of the...

Hi all, I'm close to sending the below to my tank builder but would appreciate your input before I do. :grinning-face-with-sweat: It's pretty much a standard 6foot with an internal bean animal overflow. 6ft x 24" x 24" (170G) I will be aiming for 3-5x filter turnover. Does the 3 x 1.25"...

Hi, I have a question regarding a HOB skimmer I own. It’s the bubble magus E3 HOB, I finally got it tuned recently but when my gf fed the fish one morning it went crazy out of no where and overflowed out the collection cup after I fed many times and it was not overflowing. Tried to re-tune it...

Given all other factors being equal, do you prefer an internal overflow or an external overflow and why? Adding in the mention that innovative marine uses a coast to coast overflow which I really like, and I have an internal IM 50g tank already. ..... but I also like the aspect that the...

This is one of four siphon drains. There will also be four backup drains. Is this the appropriate height for the siphons?

Hello everyone. I'll try to keep this as short as possible. My apologies in advance if this is the wrong place to post this. Essentially I plan on using this 47.3x13.8x13.8 rimless aquarium to build a custom reef tank with an external overflow and sump. I'm no stranger to reef tanks but I am...

Hi, I’ve just bought a Reefmat 500. I’ve installed it and now my emergency outlet pipe is pouring water into my sump. Meaning that the water is bypassing the Reefmat altogether. I’ve adjusted the flow rate from the main outlet pipe but it makes no difference. Can I somehow work both pipes into...
