Has anyone managed to find the overflow / forward length sweet spot with a Red Sea ReefMat 1200? Been running for approx. four weeks on my Red Sea Peninsula 650 and finding it impossible to tune my overflow so that it isn't either using the emergency drain or the dreaded constant overflow...

Alright, The S-400 did sell and it was drove out of state last weekend. Hope all three buyers are happy with their items. We always had a roll top desk before the S-400 was bought and a Red Sea 130 set on the top. The top’s wood was toast while the 130 was on it. Then when we moved in the...

TL;DR Building a smaller version of my dream tank, focusing on Red Sea ecosystem and Apex Monitoring/Automation I have always wanted to do a build thread to document everything, mistakes, successes, growth, and failures. My first shipment arrived yesterday, so it begins. So much has changed...

Hello, While having had a tank crash in my 10-gallon I want to take the opportunity to upgrade to a new tank. I have been breaking my head for the following tanks. Waterbox AIO 35.2 or the Red Sea reefer 170 G2. The only reason I would go whit the waterbox is just how easy an AIO is. I once...

Looking at getting a larger (to me) tank. What are peoples thoughts on 50-60 gal systems such as the Red Sea Reefer 250, the Waterbox Marine X 60.2, etc? As well as a thoughts between the two companies (quality, customer service, and such). I am planning on making a purchase this weekend and am...

So I just got trace colors from Red Sea, I am using about 52 ml weekly of calcium on my 200 gallon system, let’s just say 50 ml for this Scenario this week. Would I be correct to say that I would just dose at 5ml of each element this week? Would that be correct?? thanks in advance!!

I have been reefing for over 8 years now and I am finally becoming more serious about coral growth and parameters and the overall health of my tank, rather than just reef keeping. I recently purchased and made the move to a Red Sea Reefer 525 XL. It has been set up for a little less than a...

This tank has been up and running for a bit but I thought I'd start a build thread for it. Monday 17/01/2022 I bought a second hand Red Sea E260 from my LFS that came with all equipment including the sump upgrade for $5000 AUD. about $3700 USD Tank 2 x stock Ai Hydra 26s 2 x return pumps 1 x...

I recently purchased a Red Sea Reefer 250 and found my plumbing looks a lot different that what others are putting together. I'm hoping to add a ReefMat and trying to figure out how to add my Control Panel Slide Out 25 where I would prefer it go but there are pipes here. However, the videos...

Hi, Im thinking of upgrading to a larger aquarium and going from weekly water changes to monthly water changes with dosing. Im trying to figure out how much I would need to dose each week / day to get the right amount of each element (and then getting an estimate of how much it will cost me.)...

Just getting back in so not sure if to spend on the Hanna checkers for calc alk mag and phos or purchase something else like red sea or api or any other out there now

I just got the trace color ABCD from Red Sea. My question is can I equally mix all four together in a separate bottle and dose it all at once using my Neptune doser? Or do I have to keep them separate and individually dose? Thanks in advance

Wanting to upgrade some stuff! Anyone selling a trident system to improve my monitoring, also looking to buy a Red Sea skimmer, ideally an RSK 600, but open to a RSK 300, also a salinity probe for Neptune,

I know this is controversial, but there is no way red sea tanks are worth the money at all in the slightest. I bought a red sea 250 after moving and needing to downsize from my 150(which was just a standard 150 from planet aquariums I purchased from my lfs). It was somewhat sudden and I didn't...

I got a new router for new home network and I need to change the ReefDose/ReefBeat. HELP! Thanks

Hello everyone I hope that you are all well. I wanted to get your views on my aquascape. I'm new to the hobby. I've used all dry rock at the moment. I will add some live rock to it at some point. Will there be enough hiding spaces for fish. Im planning on having a mixed Reef with corals. The...

Hello Everyone I hope that you are all well. Wishing you all a very happy new year. I am currently setting up my first tank red sea reefer 625. I wanted some help with the stock list. I'm almost ready to start it up and cycle it. This is a list of fish that I would like to keep. Wanted to...

This is the refresh of my original 3D Printed Test Kit Organizer Tray thread. The first post showcased now-old designs and one had to dig through the thread to find the new stuff, so a new thread was made to clean things up a bit as the old cannot be edited (Old thread will be deleted/closed by...

Hello everyone, I've come across two designs of the Red Sea blue bucket salt, but not sure which is the current version and which is the old version. One bucket gives measurements for 35.5ppt where the alkalinity is 7.7 dKh, the other design gives measurements for 35ppt where the alkalinity is...
