I am planning a 5 ft x 2 ft x 1.5ft LWH FOWLR build and would like to have a closed loop since I do not want power heads for aesthetics reasons. I am aiming to have around 1500gph an will be using an old 40 gallon aquarium as a sump and I was wondering if that would be ok in handling the flow...

First, a peak at the result. After about 30 hours over 2.5 days, that is the finished product. Now the process. I have a 350 gal, two tank, shared sump system in the living room next door. But there isn't enough room in the cabinet or the living room for all the equipment, let alone a...

I have been reefing for a little over a year now. I can not seem to keep coral happy but its ok; frustrating but slowly figuring it out. I purchased a red sea xxl750 v3 second hand (steal of a deal for the setup) and it has been good to me so far but ....... I keep seeing the failures so it's...

Any recommendations on GPH for a closed loop system? It has one 1.5" drain and four 1.5" return lines on the back wall of the tank. The display volume is 300 gallons. It has a sump with two overflows and four 1" return lines. Approximate head height is about 4.5 feet. I have the...

I have never plumbed a closed loop system before. Recently purchased a 300 gallon aquarium with 1.5" bulkheads on the returns. Having a difficult time deciding what the best way to connect the 3/4" loc-line. Any links, tips, info you can share? I haven't purchased and loc-line or adapters just...

Hello everyone. I currently have an 8-watt UV sterilizer hard plumbed from my sump to my DT, acting as a secondary pump to the DT, along with a direct line from a Cor pump. After reading more, I understand it's better to have a closed loop from the DT directly back to the DT. How important is...

Hello everyone, just set my new aquarium on its stand and I'm starting to rough out a plumbing design. We've just received a Planet 310 that I'd added a couple of extra holes for 1" bulkheads in the back glass to feed a closed loop UV system. I've got a Aqua UV Classic 80 watt unit that was...

I have a general "how to" that requires someone with experience since I've only used closed loops with an Iwaki in a 50gal. I have one closed loop plumbed on a 150g tank (5ft x 2ft x2 ft and on one side I will have a 1" "spray bar" type setup that houses 2 random flow generators with eductors...

The VCA 134-Gallon Cube - Random Flow Generator Powered Mixed Reef! The first of two new offices tanks are officially under way, and I can’t wait to share it here on Reef-2-Reef Our goal with this tank is to build a mixed reef tank with a unique flow solution that utilizes just Random Flow...

Hey R2R, I primarily read through my local reef forum. However I wanted to make my build thread here to get a broader range of inputs on what I’m doing. I’ll likely stick to my plans but it’s always good to hear other opinions. I grew up with a reef tank in my house, but never dealt with its...

I’m getting ready to do a closed loop on a massive reef tank. This tank is 20’ long by 4’ wide. I drew up a diagram on the computer of how I’m thinking it should be, hopefully you can understand it. I wrote next to everything to tell what it is. If you see anything you would change please let me...

Hello, I am about to start a new build. I was able to get a tank second hand that fits perfectly in my house. It is drilled for a closed loop style to go with a standard overflow sump filtration. This excites me as I don’t like the look of any cords or equipment in my display including...

Hey all, I am planning my next tank build. It will be a 340 gallon tank (130"x24"x25"). I am going to do 4 separate closed loops. Ill attach the picture. each color is a seperate closed loop being run by either an ecotech vectra L1 or a Reef Octo Varios-8. Im not sure which pump to go with. I...

Hi hoping some of you can help me decide on the placement and size of the holes/piping for the closed loop I want to run on my new Peninsula tank. It is a 7x3x2 ft tank and i don't want any wavemakers on the viewing panes so going to run a closed loop. I am happy to have wavemakers on the weir...

Hello everyone. I should have done this a while ago as no matter how many threads or videos you read and watch, nothing prepares you for the real thing. Here is my story. A little over a year ago I decided that I wanted to get back into the hobby, so I started researching, reading and watching...

So, I purchased a tank recently with a internal overflow. I have a Synergy overflow on my other reef I plan to install on the new reef. As I was contemplating how to plug up the holes in the bottom after removing the internal overflow, an idea came to me. Why not turn the existing holes into...
