redsea 250

Starting a new thread for my IM100 tank. My old tank is a Redsea 250, now I’m adding a new tank. The plan is to plumb both tanks together to reduce my maintenance. Here’s my old build thread which I haven’t been updating for a while. Adding a recent picture for my old tank. It gets way too...

Hey everyone, so I had the opportunity to pick up a used RedSea 250 G1 from a local reefer/friend. The tank was in great shape minus the front seal starting to show separation halfway down the sealant seam at the base. To preface, I only bought the tank as to experiment and remove the front pane...

Hi. I bought a used redsea reefer 250 with damaged interior seams. I the price was cheap for the tank so I bought it and decided to remove and replace the interior seams, but I noticed I have cut into the main seam along the bottom too. I made sure to scrape off any residue silicone and I also...

My RedSea reefer 250 has been up and running for about 18 months now and I’ve never really filled it with many fish. I had a few Anthias but I was unsuccessful with them, so now I’m only left with a pair of clowns, a yellow tang and a regal tang leaving me with no more little fish to admire. The...

<re-posting to create a BUILD thread> Sorry for the duplicate Hi friends! Creating a build thread. I currently have a 9 month Reefer G1 9 month old RedSea. It's on our middle floor and somehow talked the wife into an upgrade. Bought a WB 180.5 and will be going into the basement. Overall, I...

Hi I’m about to setup my tank and buy the last few remaining pieces of equipment. In my sumps first chamber I plan on putting a sk-3000 Gen3 Roller Filter the chamber is just big enough for it. The 2nd chamber which is the refuge I plan on putting a baffle to split it into 2 chambers. One for...

Hello, I have a Redsea 250 and I cannot maintain the recommended levels of ALK/CA. Before I was using Seachem Part A/B and it didn't really do anything to help raise levels, I ended up losing three coral. I went to my LFS and picked up Redsea Part A/B they said this will do a lot better because...

Have been reading the threads here for a while so thought it was time to join in. Not long upsized from a Redsea max nano to a reefer 250… love the tank but already thinking should have gone bigger. Looking forward to chatting and sharing with the forum!

So basically I acquired a RedSea reefer 250 from FB marketplace and there was no plumbing included. I So I need to custom plumb this entire thing, currently there is 1 1/2 bulkheads but no threads on the other side. The bulkheads are currently glued. I was thinking of keeping the drain &...

This past weekend we officially became owners of a Red Sea Max C250 AIO system! When we picked it up we thought the tank looked like it was relatively clean. BOY WERE WE WRONG! Here is what we started out with: I'll admit, it's probably not the worst tank you guys have...

Hi! My name is Derek but my friends call me D. So please feel free. I’ve had a 32 bio cube for over 7 years now. I’ve done very well with it and for the most part I love it. I’ve learned, often times, the hard way what will and what will not thrive under the hood of a BC and it’s limited...

Hello everyone, So, someone offered to trade me a red sea reefer 250 tank, stand, sump, and original plumbing for two of my mp40s. What should I look out for in the tank? I'm trying to do some research and make sure everything's included. The tank is a few years old. Any small pieces I...

I have a redsea reefer 250 with a kessil ap700. I tested my par with an apogee 500 par meter. Light is 10" above waterline... and about 6" below water at 100% I was barely hitting 300 par. (Ie 297 par). While I want to eventually hit that 300 par, I don't think running my light at 100% is smart...

Hi everyone! Unfortunately our biocube has a leak, so we are upgrading to a RedSea Reefer 250. The LFS we went to sold us a Danner Supreme Aqua-Mag Model 9.5 for the return pump. RedSea recommends a flow of 660gph for the return pump. It looks like this return pump would have a flow of...

Two years ago I dabbled in the hobby for a short period. Being new to the hobby, I decided to go the cheapest route possible as all of this was like a foreign language to me. I purchased a 75 gallon tank and stand at the large pet retail chain for $200. I purchased all of the other necessary...

Hi everyone! I'll be starting a new reef tank in the next year or so, and wanted to get a head start on what I'll need, tips and tricks, etc... I've been keeping a freshwater planted tank for the last 3 years, and will be making the plunge into the reef world, as I think the contrasting tanks...

Hello i need some opinions, I have some one that is willing to sell me their reefer 250 v2 with stand and sump for $400. Needs cleaning of course and he said we can do a water leak test. ive never purchased a used tank before, What are things I should look for? And/or should I buy a used tank?

I just pieced this up together and I'm really liking the high cave look. This will be going into my Red Sea Reefer 250. You'll see the top view with the egg crate that is cut out for the reefer. That's going to go on the bottom obviously. You'll get an idea how it looks. Except I'm going to turn...
