Hey all! The time has come to sell my wife and I's awesome setup. If you would like to see our tank's journey from start to recently, our r2r build thread can be found here. We have loved this tank so much, but we are getting ready to move and with our current plans, we just think they would be...

So I w been in the hobby one and off for about 10 years. Always 10 - 20 size tanks so I somewhat know what I’m doing lol. I always get my premixed water from the same LFS I go. So earlier last year I started a new tank went to my LFS for water and they informed they switched Red Sea Salt to Red...

Please take a look at this photo and let me know your thoughts on what appears to be a bubble in the rear seam of my Red Sea 525 XL. I haven't noticed it in the past, but do not see that area of the tank often, as I have a screen cover. Marking now with sharpie to monitor. How long do I have?

I'm going to be moving soon and im looking to break down / sell my S-1000 G2 system that is about 2.5 years old. System is in good condition, but does have some scratches on the front glass. I am only selling this tank because I am not sure where a tank will be in the new house yet, and i plan...

Hi Reefers, starting a new build thread (which by now is an old build thread as I've already moved on and have another iron in the fire 🤣), but I wanted to document that build and update my profile's build thread while I'm working on the new one. Previous builds (These aren't all of them. But...

Hello. I purchased a Red Sea Reefer S-850 G2 at the end of 2022 and have had no problems thus far. The bottom seam and other seams look good. There is one questionable side, see pics. I contacted Red Sea and they said the seam is acting as it should. Should I be concerned with this?

I'm trying to work out whether I’ve been uniquely unlucky or accidentally enrolled in a long-running product test. Reefer Max G2+ 300 bought Dec 2023, set up Feb 2024. Since then: six ReefATO+ sensor replacements. To be fair, Red Sea support has been responsive. Each time the sensor fails, a...

Finally moved in to my new house and started setting up my dream tank. Unfortunately, I bought a Red Sea Reefer 250 from someone nearby. The bad silicone was not noticeably when the tank was full and I was not aware of how poorly the Red Sea tanks were made. When I got it home I noticed the...

Hi all, Like many of you, I tried the gate valve mod after suffering with the stock red sea valve for a year, and while it was much better, I still had to tweak it now and then (especially after doing a water change). I needed it to be below the emergency overflow and was adjusting it every...
