Hello, I've had a Redsea Reeftmat for almost a year now with my Bashsea Smart Series Sump 36". The drains on the Bashea Sump are 1 1/2" so I've always just shoved the flexible tubing of the reefmat into the drain pipe of the sump and its work fairly well. However, I just want to clean up the...

Hey there, I have a new RedSea REEFER SKIMMER 300 I'm looking to sell. I’ve been running it for about 3 weeks but I just think it’s too oversized for my ~30 gallon tank. I recently bought a RedSea REEFER G2 170 and it came in a bundle with the tank so I assumed it is appropriately sized but...

Hi Everyone, I'm newish to the hobby (tried reefing when I was a teen and am revisiting it in adulthood) so would love some advice. I have a RedSea Reefer Skimmer 300 on my RedSea Reefer 170 G2. Total system volume is ~38 gallons which is decently below what BRS recommends for this skimmer...

Hey everyone, just want yall's opinions/recommendations on what my next build should be! I currently have an older BioCube and want to upgrade. I am looking for a tank somewhere in the ballpark of 65-100 gallons. I know almost everyone here would probably agree that I should get a system with a...

What's everyone's thoughts one the new redsea peninsula? It looks great and love the hidden feet, but seems weird they got rid of the above sump ATO reservoir. I'm sure it's to accommodate their filter roller and skimmer sticking out above the sump, but they don't seem to have much room for an...

Hey everyone, I recently upgraded my lights on my large system and shut down my smaller system so I have some items for sale. Kessil A360X's Qty 5 1. I upgrade my current tank and the dimensions just don't work very well with the A360x's. I had them for about 1 year and they worked great. I...

ReefDose should be delivered today, my plan is to mount it dorectly on the right side wall of my sump. (Reefer 250 G2). Has anyone installed an effective shelf or basket for all their supplement bottles under the doser? Or should I just leave them directly on the floor of the sump? Trying to...

I should really have started doing this a couple years back. NO3PO4-X usually sells for $45 give or take, and I could make so much more by just buying the Vodka, Vinegar and mixing in with RODI so what follows is a Quoted recipe from a 5yr old Nopox Recipe thread that I found on R2R. Credit goes...

Hello, I have a brand new in the box RedSea Reefer 900xl G2 with white stand and sump for sale. Price is $4500 for everything In January my 900 G1 version leaked with a bad seam, RedSea wanted to warranty repair the seam and I threw a fit and they sent a new set up instead. The new G2 is...

Full Tank Shot as of 7/19/2024: Come one come all, welcome to my build thread. First, a bit about myself. When I was 14 I stumbled into an archaic corner of YouTube where people were keeping reef ecosystems in little glass boxes. I was hooked and immediately wanted to join in the fun. My...

Hey all, getting a new tank and these are going to be way too powerful. Ran these are my 200 gallon for a year and a half. I have two Red Sea Reefwave 45's with controllers along with some replacement parts. Bearings were replaced about 2 months before breaking down the old tank, they are still...

I have two RedSea ReefWave 25 powerheads for sale. They’re just a little overkill for my 40 gallon mixed reef so I’m downsizing. I am the original owner of one, and bought the other one used. Both are in excellent condition and are shown in the pictures below. Both have been well cared for...

For Sale are 2x RedSea 90w LEDs Both come with a mounting kit and will be sold as a pair. These lights have a double adapter cable so they will only need one plug. The lights were only used for 8 months at 30% intensity on a shallow tank. Everything works! I will include screws but no wall...

I’m selling two RedSea ReefWave 25 power heads. I am the original owner and they have seen light use for the last 8 months. They are in excellent condition and have been cleaned only with citric acid solution. These are fantastic pumps, but are a little overkill for my 40 gallon lps tank...

Moving Soon and would like to Sell this tank, only setup for a few months, no scratches and comes with everything shown, also a custom Kraken reef lid which are pretty expensive

Just bought home a RedSea reefer 250 g2 and am in the process of getting the plumbing put together now. We plan on installing both a reef mat and a skimmer on this system, and part of me thinks it would be easier to connect it all now in the very beginning before getting water in the system...
