overflow box

Never used. Was purchased before I realized I was able to drill my tank. Will ship to buyer or will discount for local pickup.

For a drain… When transitioning from 1.5” to 1” is it better to use a 1.5” to 1” bushing or should you gradually reduce with 1.5” to 1.25” bushing with a section of 1.25” pipe then a 1.25” to 1” bushing?

Currently have a 20" Synergy Reef Overflow purchased in 2020. I recently reached out to Synergy Reef for support and was told that they have discontinued the 20" models. What other external overflows are recommended that will fit the already drilled holes for my Synergy Reef Overflow. My tank...

So after I cut my first pieces of glass and remembering the projects other reefers had posted, I realized that I need to make a post about this project. So I have a 75gal tank that currently houses a couple ciclids that I will be re-homing. I have decided that I want to take my 15gal nano and...

Hello everyone, So I installed a overflow box on my rimless tank. Everything seems fine but there's a very small leak where both pieces connect in-between the glass. How would I fix this? Thank you

Hey, I made a 3D printed overflow for my 220 gallon and I just wanted to share my process and my blueprint in case someone wants to use it. Been using it for 2 months now no leaks or anything like that and works great. Also cost around 50 bucks, $40 for the 5 bulk heads. 10$ for the filament it...

Looking for a Nano Eshopps Overflow for my 10g project, lmk what you have, thanks!

So I want to change the inside part of my overflow because I hate it, the box on the outside is fine I guess but the overflow “screen” drives me nuts, so my question is how can I change this to a normal overflow box? Is t possible? The drilled hole is 1 1/2 inches o just want a box inside my...

I just finished drilling my tank for an overflow, followed the template, and the interior box hits the glass lip on the inside of the tank. Most tanks I've looked at don't have the lip, so is it safe to cut that piece for some clearance? What is the best way to cut glass that thick that is...

This guy recently split. Yesterday he shrank down small enough to go through the weirs of the overflow box and now he is anchored in the corner where I can barely touch him with a pencil. What the heck can I do to get him to come out???

Hi all, I probably should have posted it here in DIY section but I was not sure where it may fit in. I was wondering what was the best way to move forward with this problem and if you had any insights, that would be great. Here is original post...

Hi all! For a little background, my boyfriend has been planning his reef tank for about eight years (he even chose his apartment in the city he lived in before we met so it could sustain a 400 gallon reef tank). After a 29 gallon gift, 100 gallon tank COVID project, we now have a 100gal tank...

Scraped this off the back of my 10 gallon nano. Tried to just use ceramic Magnets to allow to adhere naturally but consensus is that this is asking for trouble. got after it tonight with the reef glue...have to press lightly but hold for 20-30 seconds but it will stick! Also have to make sure...

I am planning my first reef tank (75g that is currently freshwater) and am having trouble deciding on the HOB overflow that I am going to use. I cannot drill the tank because it is tempered so a HOB overflow is needed. Since it is in our living room, it would need to be as quiet as possible...

I recently purchased a 36-gallon Bowfront tank with the intent of establishing a reef. It has been a dream of mine for years now! After watching some videos I think that I will be able to drill it! Just have to call and confirm that the back is not tempered first. My question is... what size...

Hi Guys, new to R2R, but a long time lurker. I have been using this overflow for about 2 years now with no trouble, so I figured it was time to show it off! It will overflow about 2-300gph to my sump, and will automatically start and stop when the water level rises above the baffle just before...

I currently have a IM Fusion 20 about 3ft off the floor. I’m planning on adding a sump for additional water volume, clean look(hiding equipment), and a good sized Refugium for nutrient export but mainly for copepods. I cant/don’t want to drill the tank so a hob overflow box seems to be my best...

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...

hey everyone, i’m looking to start an under tank refugium for my 30 gallon but drilling is not an option. i was wondering if you can post some links or recommend good or the best overflow boxes for my size? thanks! the fuge will be somewhere between 10-20 gallons

I am complete novice when it comes to sumps and plumbing. I have a 120g tank that's got a Trigger Emerald 34 Sump installed underneath it and a Reef Octopus Varios6 return pump. Since the tank is tempered glass, I have no choice but to go with the overflow method as a means of moving water to my...

Afternoon All, I thought a quick post regarding this product may help people with the same issues I faced. Having moved from a fully planted freshwater setup I was desperate to keep the original tank and stand (Evolution Aqua Aquascaper 900) 1. To save money 2. I like the overall appearance...

I knew the basement floor was unlevel, it with my custom coast coast overflow *48 inch. i still am only getting 3/4 of the length letting water in. I believe the right side lowered 1/8 at the most would solve the problem. Unfortunately this is a custom design I did, and the overflow does not...
