red sea

is this a sign my tank is starting to leak?

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?

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...

We’ve just bought our new home and I finally have the space for my first “big” tank. We’re on a concrete slab and I have room for up to an 84” tank! I’ve been doing some shopping, and ultimately I really like the Red Sea S-1000. I like it for its look, dimensions, and I like the sump layout as...

Hey guys, I have a 3 year old Red Sea 250 G2, bought in early 2022. While cleaning the tank today I noticed a small section of the silicon on the front bottom pane is starting to get discolored from the top. Kind of looks like coralline algae got in between the armored seam and the silicone...
