overflow

Took down my reef and looking to sell the Mame overflow and float switch. Super cool minimalist look for a rimless tank. The overflow and switch are both in perfect working order. I replaced one of the soft tubing sections to lower the weir so the water was about an inch below the tank rim (see...

Bought this overflow for a build a while back but the tank cracked before it even cycled. The new tank I bought came with an overflow so I have no need for this one. All this thing saw was water for a couple of weeks - didn't even get a chance to add a single fish. It's in like new condition...

I have a used, for 3 months, 2500gph synergy reef overflow. I also have 3 of the 2” drain lines if interested. Asking $140 shipped. If you want the piping that will add a little extra to shipping costs. Make an offer.

Hello! My first post! I’m looking for help on how to plumb this specific overflow system on a quarantine setup. My plan was to use three slip in bulkhead fittings with a downward slope and 90 degree elbows , Am I on the right track. I feel like I’ll need to use flexible tubing? The tank...

Hello all, I made a diy pvc overflow see picture below and I was wondering if anyone had any ideas on how to get a little more gph out of it. I'm currently running a inovative marine 25 lagoon aio with 2 returns. Totally water vol is about 17g after rock and sand. I was planning on running 2 of...

First post! I’m setting up a Waterbox Peninsula 7225 and had a question re: overflow. This is my 4th setup so I have a bit of experience fine-tuning return and return pump flow, but I’m wondering if someone has had any experience with Waterbox and can offer some advice. As I’m tuning my...

Hey everyone, I'm coming back into the hobby again after about 10 years and I'm super excited. I've had the opportunity to inherit a tank 215g (72x24x29) from my retiring uncle and need some advice on what to do. I've already gone ahead and broken down the tank, storing the rock in trash cans...

Hi all, (this might feel like a double post as it links back to the main one so admins feel free to tell me to delete!) I tried the gate valve mod and while it was a tonne better, I found I still had to adjust it every so often especially after turning off the pumps to feed corals or doing a...

Just picked up a brand new Aqueon 75 Gal, Drilled and fitted with an Ehopps Prodigy M series overflow. Slim n Sleek. Tank is much larger than i expected - i was planning on adding this into my plumbing as a separate holding are, to replace my current 10 gal plumbed in. I may still do that but...

Got an Eclipse l and after much time, I finally got it plumbed to the best of my ability in the bean animal style. However, I for some reason watched the ONE YouTube video where the person cemented their inner overflow in, meaning I can’t pull out any of the elbows because they are cemented into...

Hey guys, I’ve been away from the hobby for quite some time(10 years) but am eager to get back into it. I purchased a 60g breeder as it fits my space perfect and it’s a big enough platform to have some fun with it. Much has changed in the past 10 years that I’m looking for some advice on a few...

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...
