red sea

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...

I purchased this skimmer a few years ago and then I ended up not using it. It's brand new in box and factory sealed.

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...

i'm in search of a red sea reefer 350 lid (V3), no specific brand, thanks!

Hey all, so I’m in the market for a smaller tank for my daughters room since “she loves fish” and to have a bit more room for growout. I’m looking for something in the 25-40 gallon range. I’ve always been a Red Sea fan and still have connections through my former store for their tanks, so have...

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...

I bought a Red Sea ATO upgrade kit about 10 days ago. Installed in my Reefer 350, got erratic behavior - inconsistent fills between 0.05 gallons per fill (which would be the expected top off volume per fill given 25x25 return chamber and 3 mm between sensors), up to 0.8 gallons per fill with...

Four units available! $249 each. I used eight of these on my 1000G system and I am downsizing since they put out so much flow (4000GPH). All four of these work perfectly and are clean and ready to give your tank a strong sheet of waves. UPS Ground shipping is $7 for one unit, and a flat $10...

ITEM SOLD Hello, I'm working on breaking down my tank and want to start off with selling my dosing pump. It's very slightly used and like new. It comes in its original box with all original equipment. I'm also throwing in some free colored tubing to use with the dosing pump. I'm asking for...

Looking for a used Red Sea Reefwave 25. Needing it for my Max 250.

Want to purchase a 150x75x60cm tank (LxWxH) and not sure to go with 2 Red Sea 160s or 3 Red Sea 90s. Which would be more optimal for coverage, plans are to run some soft coral mainly with a few sps corals

Hi fellow reefers I need a little help figure out the best way for cable management and overal control panel placement in the xxl750 stand v3. I have looked for inspirations and pictures for the last 4-5days but still can’t find what I’m looking for without having to dyi. I’ve seen people...

I have a red sea reefer 350 g2 tank (75-gallon display, 17-gallon sump) and I'm shopping for a red sea protein skimmer. My LFS has a sale on the Rsk 600 AC for $400 and the Rsk 300 DC at $415. I don't know what to get between these two because I heard that oversizing your protein skimmer is bad...

Selling a G1 RSR 525XL with the V3 sump already modified for use with the included ReefMat 500 in great condition. This tank was purchased new from saltwateraquarium.com in October of 2021, so it’s less than 2 years old and was only broken down 7/1 of this year. The tank has been cleaned and...

I have not had a personal tank set up at my house for the past couple years after a catastrophe claimed my 300 gallon (3 day power shutdown over high winds, while out of town and no cell service, luckily my brother was able to rescue a lot of the livestock). However, with the recent birth of my...

I'm sure you all have ran into this question a thousand times but I'm looking into getting into the reefing hobby after doing freshwater for so long. I've found these 3 companies seem to be the big players I see others talk about. I think the red sea setup looks sexy, but I've heard that they...
