red sea

Hi all, I've been working on this project for a bit, mostly for myself, but a few people told me that they'd want one or that I should look at making these for others. I thought it would be best to jump onto the forums and show a quick example of what I made so far and see what sort of...

Well as expected I am a recent victim of the Red Sea G1 tank failures…although it was somewhat planned for…I had lowballed my local shop for a new reefer 250 based on the known risks with the G1. Knowing I could get the extended warranty with a new tank and replace it if a problem arose. I...

Hi All, I am a glutton for punishment. Last year I stood up at Waterbox and 4 months later had a job transfer. Last minute I went to post and sell it on here then my company agreed to move all of it. They broke the Waterbox on the move. Being passionate about reefing and moving to Orlando I...

Redsea max nano 20g aquarium used for less then a month then put back in box went a different route! Tank only asking $250 local pickup San Diego

Hello, I recently installed the Red Sea Nano Mat into my Red Sea MAX Nano G2 XL and have had issues with the water level being too high and water just bypassing into my return chamber. Not sure if anyone has had this problem but I’m not sure what to do. Thank you

Used but in great condition, perfect working order and recently deep cleaned. I needed to add a few items to my sump so I no longer have space for the RSK. Would consider a trade for Hydros related stuff. Make me an offer! Based in Longmont, CO. Will not ship.

2 used Reefwave 45 wavemakers. Both never used at higher than 30%. 1 is a year old and comes with box and all included accessories/parts. 2nd pump is 2.5 years old with a new controller. Both WiFi controlled using the ReefBeat app. Both work great just went with different brand.

Hey folks, got this little silicone loosening that I noticed recently. Nothing is leaking yet and I am monitoring to see if it gets worse regularly. Wanted to see if previous/current Red Sea tank owners would know if this would eventually lead into a leak? Thanks in advance.

Looking for reviews on the nanomat. Doesn’t seem to be many reviews anywhere yet (I’m assuming because they are still so new) but I am just looking to hear users thoughts on it so far. I am considering using one in my reefer 170 rather than using a reefmat 250 and loosing half my sump space...

So hi… I kept aquariums from my teen years through to a few years ago when I had a motorcycle accident. At that point - though my injuries were being dealt with - it became very difficult for me to maintain my aquariums so they were closed down. I have had several surgeries since then and I am...

Vote for your favourite roller filter! Let me know if I have missed any.

Hello everyone, first time poster here. I've not had a reef tank for around 2 years, and I am currently looking to get another. I am considering a Reefer 170 or a Reefsys 180. I'd like to see how everyone has theirs set up in terms of aquascape and sump equipment - anyone using a roller filter...
