red sea

Hello! I woke up this morning to another bloom of white slime all in the sump. The only thing I have changed on my tank is adding the Red Sea reefdose system 2 days ago. I have it dosing the usual, alkalinity, calcium, magnesium, and nopox. I have the doses all set to Red Sea’s recommended...

Hi, I seem to have a tank that's causing a clash of opinions on what size light to get. My tank dimensions are: 4 L x 20 W x 23.8” H and i have a fairly flat scape; 4 rocks in a row, kept basic for coral real estate and basically no shadowing. I keep LPS and softies- nothing particularly rare...

Hi. I have an all in one 20 gallon Red Sea Nano Max. I clean the protein skimmer cup weekly. But there is build up at the bottom of the skimmer. How do I best clean that. Do I need to take the entire assembly out? Thank you!

I recently purchased a 65 gallon Red Sea aquarium on Offerup. I currently have a 32 gallon Biocube stocked with 4 fish and I am planning on transferring these fish into the new tank. However, the nitrates in this new tank are fairly higher than my Biocube (40 ppm versus 10 ppm). Is this too big...

Stay tuned for details -- I figured I should confer with the admins;)

I recently purchased a 65 gallon Red Sea tank on Offerup. The owner was including all of his livestock along with the tank. One of the fish included was a fairly large blue tang (about 6-7 inches). I understand that he is likely too large for this tank but I had no choice but to take him. What...

Hi, on the package it says "0825 12", does this mean that the product expires in 2025 or in 2012?

Well, here I am. The prototypical cautionary tale: I bought this tank with big dreams and genuine interest, but because multiple life reasons and changes, it has been sitting in the garage since I picked it up in late 2018. Finally, I'm now relocating so I can't put this off any longer. I have...

I am water testing my new Red Sea 3xxl 900. When I filled up the sump which sits on a foam pad in the stand it looks as though there is water or air trapped under there, or just that the foam is being pressed against the glass more in a specific spot. I did notice this right away, however...

I dropped one of the vials for my red sea nitrate pro test kit a couple of days ago and I can't seem to find replacements for them online, does anybody have any ideas where I can get them?

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...

So I hard plumbed my Red Sea 170, I filled it up and it is running well so far. I do have a tiny leak but that is not what I am worried about lol. That should be an easy fix. My concern is in the emergency drain, middle pipe, and the weight of it caused by how I hard plumed it. With the entire...
