I recently switched from Red Sea dosing products to Seachem products. I emailed Seachem and they were nice enough to send me a calculator excel sheet on how much to mix with RO water to make a stock solution… this is where I’m struggling I am now almost double the daily dose of the Seachem...

Good Morning everyone. So I've recently picked up a Red Sea Reefer 425XL. The silicone seals all look fine, but the horror stories I've heard have made me want to bulk things up a bit. I've reinforced each corner seam, but I'm thinking of adding a brace to sit on the top of each side of the...

I’ve wanting to dose trace elements. I was wondering if anyone does it without doing icp test all the time. I was going to use bright wells trace or Red Sea. I want to use Red Sea though cuz everything I use is Red Sea (products wise). Any suggestions or opinions are great thank you.

My Red Sea 425 XL has a seal issue and I am currently speaking with them to get a replacement. So I might have to empty my tank, take it apart and rebuild a new one. 1) Any and all comments/tips/suggestions are welcomed! 2) If I am going to do this, I will also make some changes to corals and...

Has anyone had issues with their roller made wasting HUGE amounts of filter paper. 2x now in the past 2 months I’ve had my mat use randomly over 500 inches in one day! It usually should be around 40 inches. Seems to be related to the sensor getting dirty I think. I’ve been cleaning it every...

We bought this customizable net cover kit from Bulk Reef Supply, but ended up not needing it. It is still unopened in the original packaging that BRS shipped to me. $50 local pickup, or $70 for shipping and to cover Paypal fees...

Something strange is happening with my Red Sea Calcium Test kit. When I drop in the powder, some of it turns to little stones. And I’m guessing it is messing up the result since some of the powder is not dissolving. I bought the kit new less than one year ago. I follow the directions precisely...

I have two Red Sea Reefwave 45 gyres for sale. I used eight of them on my 1000G system and that was overkill (they push almost 4000gph each) so I'm downsizing to six. All come in their original boxes -- everything as if they were new. $499 for the pair. Shipping is available via UPS Ground for...

Mount only, as pictured. $50 OBO and willing to ship

Hey all, I'm back for more punishment and maybe some enjoyment this time. I've really strived in the past with smaller tanks and I'm hoping that continues for me here. I've had 180g tanks, 20g tanks and everything in between. My last experience with winning the RS 525XL on here was not...

Looking for the Red Sea rsk 600 skimmer. I have a reefer 350 with the rsk 300 but would like the larger size to pull more air through my co2 scrubber. Would also consider similar footprint/power skimmers

Just got the RS Reef Mat and noticed the level sensors on it. When I put my tank on feed mode (using GHL) the water level in my sump rises. Should I shut off the Reef Mat as well as everything else during feed mode? Thank you all for your time and input!

When I was in kindergarten we visited family in Texas. I fell in love with my aunt's 10 gallon aquarium with Mollies and Guppies. When I got home I wanted guppies of my own. We didn't have much money and my mom worked days and nights to afford the trailer we lived in. So, like usual, I went...

Selling a couple items from my old reef setup. Ended up breaking down my tank after a few months, was just too busy with work and everything to keep up with it. All the equipment was only used for about 4-5 months and then taken down and has just been sitting in my closet. Everything was cleaned...

Hello all!! I am really hoping someone can help me with this so I don’t have to replace the controller completely. My ReefWave45 is showing on the Wifi connection and in the app as a 25 so it no longer works. It’s 6 months past the warranty so they are offering a discounted controller but I’m...
