Glad I watched your video! I’m still running the original Red Sea 130 and planned to upgrade to the new 350 G2. I started thinking, maybe the 425 but now after watching your video maybe I’ll just go with the 525!

I have the same tank I I have the same problem with the emergency drain and water just keeps going down it.

i have always struggled with downflow valves when the output is that far submerged. it traps bubbles in the pipe. try shortning the pipe so its barely submerged and see if it helps.

I’m a major Sicce fan. I run Sicce pumps for every application, from maintenance to main return pumps in my AIO tanks - with the one exception being a Neptune COR-15 return pump in the sump of my main display tank. I started with a Sicce 4.0, and found myself adjusting the flow wheel every 48-72 hours to try and keep the level consistent. I could never achieve it. Switched to the Neptune pump (which is DC, whereas the Sicce was AC), fine tuned it during setup, and have never had to touch it again. It’s been 6 months. Not one single adjustment. As much as I love Sicce, Neptune’s DC return pump made my life a whole lot easier. I think general AC pumps may fluctuate very slightly over time, while smart DC pumps are precise enough to “self-correct” their output, but it’s just my hunch. Great video. Love your content.

Your Overflow valve adjustment annoyance is sooooooooooooo on point!!!!!!....Super frustrating 🤷🏾‍♂🤷🏾‍♂🤷🏾‍♂

I live in South Africa where our summers are sweltering hot. I have a G1 525XL that popped a seam. Tank was only 6 years old so good luck with yours! I managed to save the glass from shattering using duct tape. I got the tank refurbished and properly reinforced with fresh silicon all round and extra bracing down each corner, and at the bottom. Just got the tank back and this time I removed the two doors that are over the sump side, so that the sump has more air flow (as you mentioned the airflow in the sump sucks!), redid all the plumbing with hard plumbing, I detest clear tubing! Basically made the sump part of the display, neat and tidy.

Im with you on the valve.. it sucks i had to get rid of it because it was driving me crazy. Got an Aquaforest 980.. not a single regret

As a comment mentioned about atmospheric pressure... adjust your valve on a 30.30"/1016mbar pressure day, and you may see fewer adjustments. Standard atmosphere is 29.92" / 1013 mbar for reference. All aquarium users should keep FlexTape (or other waterproof tape) immediately handy, and have a couple people in your phone contacts to act for you in an emergency.

I’m with you , that’s why I went for a DD 1500 aluminium frame 😊

I have the XXL900 and it is quiet as a mouse. I turn the dial and watch the water level in my overflow. I let the water get to a point where is makes no noise and that's it. Haven't touched it since. The water change noise is normal. It takes a couple of minutes after I restart the pumps for it to dial itself back in. After that it's back to being dead silent. I would look at getting a DC pump like a COR 15 or 20 that you can really dial in.

You want a trickle going over emergency!! It will do no harm

Zburn, I'm building the same set up as you about a month and a half behind you. Would love to show you pictures. I had a black G1 350 before this one. Not sure if this would work. But could you put a quarter inch extension on your back up? Obviously not in line with the glass, might give you some room to play with the value. Honestly my is pretty dialed in. However, I do not have as much mechanical items as you yet. Keep making videos man! It's crazy that someone is building that same tank as I am at the same time and has the attention to detail I love. I had a channel for my first 350. Man it was rough. Been thinking about getting back on and progressing through this build. Have loads of videos that what need to be edited though. Anyways keep it up man. Maybe we can chat in the future.

Ive litterlay just got this huge pallet delivered today and im debating swapping to a gate valve before i even setup (cabinet is built) currently need a 2nd pair of hands to lift tank onto cabinet then i can sort plumbing and add the reefmat...did you leave the material in the bubble trap part before the return section or remove it?

Could add like a computer case extraction fan on the back?

I have just bought a 2nd hand 425. I bought it empty. God I hope there are no issues. I don't know who owned it as I am buying it from my local LFS.

I think i build my own diy aquarium all that money to pay for red sea and it not enough room or auto top off issue thanks for video

how much would you have spent to just build your own the way you want it instead of buying a pre-built? For example, think in terms of building the PC you want vs buying an alienware...

The smaller the tank the more difficult the space management. For a sump set up I would not go less than 6ft tank.

You want that little bit of drain going down the emergency pipe that's what it's there for. This is the bean animal method as described on reef Central almost 20 years ago.

There are 2 things happening here, 1 - you got bad advice from Red Sea 2 - you are worrying about this too much, a little water going down the 2nd drain doesn't impact anything. It's one of those things that's driving you crazy because you know its happening but it doesn't harm or help the tank at all. There is also fluctuations in the water level because of the atmospheric pressure, how clogged your filter socks are, if you were using a filter roller then amount of water in your filter roller also affects it. Tune the valve where the water level is further down so when it fluctuates, it doesn't make a sound. Water going over into the secondary drain still goes through the socks - no big deal.

I recently purchased RedSea Reefer S-1000 G2. It's going through Water Cycle now, but after initial installation was done, the technician who installed it asked me to get a water reservoir so that they can hookeup the ATO. After I did, i called him to come in and install it, he wants to charge me US$180 for installation! WTF. Then he text me asking if I were planning installing Auto Dosing, Wave Maker, etc. He said it will cost me the same. The last saltwater aquarium I've had was in 1990's in Miami. and it was just a 4-footer tank. This 7-footer reefer with the sump is a totally different game. When is the right time to install the wave maker? when all livestock in place, or, ideally it goes now? what about the price? Is it any reasonable at all, or a total rip off? what about DYI, any videos? (BTW, that price is installation only, the actual ATO is already here)

Indeed, the email offering a discounted extended warranty is completely intentional! Many companies adopt similar strategies with subscriptions and other products. However, hearing that Red Sea does this honestly leaves a bad taste in my mouth

I have two Red Sea tanks, and I'm so paranoid about them springing leaks

Drill the stand and attached a fan that pulls air out.

I absolutely hate the big overflow box. So many other tank makers keep the back panel flat and i much prefer that look.

Yeah it looks like the new return valve is no better than the gen one. I even fitted a high quality third party valve and it's not better. I have the same issues with drifting. And it does affect salinity. I wouldn't get another red sea tank.

Other then it leaking in less then three years?

The water overflowing into the emergency will not affect salinity. You can cut of the dumb diaphragm valve and put in a gate valve. There is no room in any of the sump areas with RedSea. I have one and probably will never buy another. I would get either water box or Innovation Marine.

i have G2 and i love it dont have any pormplam with it....

Is it not more likely the pump is the thing that's causing drift because a gravity fed tube with a valve that isn't moving should maintain a very steady flow rate. The voltage at the wall socket is not constant, it varies due to the use of power in the home and from the power supply company. Variations in voltage leads to variations in the RPM of a pump's motor. So here in the UK for example, as it's a known fact variations can occur in voltage output, there's a specified plus/minus tolerance limit set by parliament that power companies should seek to stay within, but even then they can drift outside of that. In the UK, the declared voltage and tolerance for an electricity supply is 230 volts -6%, +10%. So between 217V and 253V. Found this on the USA. "Voltage levels are often highest during the nighttime hours and weekends when the electrical demand is minimal and are lowest weekday afternoons when the demand for electricity peaks. Most electric utilities in the U.S. try to maintain the voltage level within plus or minus 5% of the nominal voltage level (e.g. 480V +/-5%), however for short periods the voltage level may be as much as 6% high or 13% low (according to ANSI Standard C84.1). On the nominal 480V system, this would translate to incoming voltage ranging from 509V (480V +6%) to 420V (480V-13%). Larger deviations from nominal voltage are also permissible on a momentary basis or may simply be unavoidable."

Warranty is quite scary I think especially for notorious G1 leaks. If the G1 leaks, you can claim warranty and they will simply replace the tank for you. Done and dusted for them. For the reefer, leaking causes more damage than just a broken glass tank. I shall not elaborate on what more damages it cost but definitely includes mental trauma. Hope the G2 doesn’t develop that reputation!

Replace it with a gate valve

I put a gate valve on mine. No issues. The ATO is a joke.

I always hit the sweet spot... 😏

I had one back in the day and I wasn't pleased with it. Waterbox was the answer.

Maggie Muffler is the solution

Too much whinging . It’s a fish tank . All fish tanks comes with little issues. If u so particular get one custom build to your own specifications 👍🏻

Socks look dirty ignore me tho im ocd lol

Worst tank you could ever purchase

There are much bigger problems in life
