Finally have the money to splurge on a Red Sea build, likely the Reefer 525 G2+. Does anyone have experience with previous Black Friday sales? Will the current 12% off likely be the best discount or should I wait it out a few days to see if there are any increases?

I have two Red Sea ReefLED160S lights for sale with mounts included. Lights saw limited use at low power. These are fantastic and powerful lights, but overkill for my new setup. The 160S excel at projecting great par into deep tanks and have a strong shimmer effect. Each light comes with an...

I wtb a Red Sea Max Nano aquarium. It does NOT have to have the stand but if it does it’s not a deal breaker. Would prefer without though. I live in Georgia if anyone has one somewhat close by.

Hey guys, I just recently upsized to this Red Sea Max 250! I love the curved edges because it’s one less seam to worry about, plus it have a hood for evaporation and jumpers!

This package has been advertised privately half the retail price & im very keen to buy it but… I’m not sure if they make knock off brands in Red Sea tanks. Lol! I know it seems a strange question but can anyone tell me how to authenticate it?!

Hi all, When I turn feed mode on in my Red Sea app, the water level in the sump rises substantially (as expected). When I turn off feed mode, the skimmer immediately turns on when the return pump does, before the sump level drops. The skimmer overflows and dumps a bunch of really watery...

Hi, I’ve just bought a Reefmat 500. I’ve installed it and now my emergency outlet pipe is pouring water into my sump. Meaning that the water is bypassing the Reefmat altogether. I’ve adjusted the flow rate from the main outlet pipe but it makes no difference. Can I somehow work both pipes into...

I am on day 14 of using Red Sea's Reef Mature program and I feel like something isn't right. First of all, I haven't had any algae at all and the manual said I should expect it to appear around day 3-4. Total ammonia is at 0.2, nitrite at 0.4 and nitrate 50. pH is a little low as well (7.8). If...

Hi Guys, I just recently setup a Red Sea Reefer Max 300 G2+ aquarium and purchased the Reefer DC 300 Protein Skimmer as a combo. I'm running a ReefMat 500 Automatic Filter Roller and the skimmer was oversized the setup. I purchased a smaller skimmer to replace it. The skimmer is like...
