reef

Hi guys! I was wondering to get some help, yesterday I saw this in my pincushion urchin, at first I thought it was just sand that somehow got on him, but when I watched him today the white thing was still on him. I took several pictures, but the one on the post is the best one I got. It would...

I’ve been using the same Red Sea reefmat for about 2 months and at first it was working totally well. About halfway through the roll u noticed consumption rate went up from about 30inches a day to 180inches. Progressively it kept getting worse till water started spilling over the sides...

Hello everyone, I just recently started my 55 saltwater up after having two failed attempts of getting it going. Both times I ended up doing something wrong that causes the tank to go wrong and fail. But, I’m determined to make it work. I recently started it back up, I cleaned out my filter...

Hello, I have been searching nonstop for anything regarding sick marine bettas and I just keep finding that they basically just “never get sick.” mine has been doing great for months. Eats great (I feed him live feeder ghost shrimp) and is one of my favorite fish. He’s recently stopped eating...

Hello, Im new to this website but I kept tanks in the past. Ive seen lots of videos and some vague posts by reef builders on a coral cycle. I couldn’t find anyone with experience so I figured Id do a “cheap” basic set up. The tank is currently 2 days old and has some of what I think are basics...

Hello! I just upgraded from a 10 Gallon to a 18 Gallon Red Sea Nano desktop and would like to set up a controller and dosing system for the new tank. The Nano is an All in one so it has a built in filter sock, skimmer, charcoal but thats it. Any recommendations on how to augment the existing...

Has anyone tried or know how to cultivate bacteria to be dosed back into the reef tank? I saw a video by WWC with the owner of Coral Morphologic, he did a tour of his facility and he mentioned that he was going to discuss how he cultivates Dr Tim’s bottled bacteria, but never got to it!

So I have had a small bubble coral colony in my 32 gallon biocube since december. It was doing well in the tank until the past month or so I started to notice a drastic regression in health. In the past few days I think it has officially died and I am at a complete loss. I made no major changes...

Hi All, I managed to find 2 pygmy rooster waspfish that were added to my tank about 3 weeks ago. I believe I have a male and a female, and they've set up shop next to each other in a corner of my tank. They sit around sticking out of their little lairs, and once lights are down they are out...

I’m planning to get a new 13 gallon tank and eventually make it into a reef tank. I was hoping to start out by cycling then adding corals and a cleanup crew, and maybe a month or so later, adding an ocellaris clownfish/pair and maybe a bangaii cardinal… I wanted to know if anyone could walk me...

So I just got home today to find that my fairy wrasse had died but this isn't what my question is about. Should I now do a water change to avoid an ammonia spike? I removed what was left of the carcass but it looked like my snails and crabs had been eating it for a few hours maybe. I did a water...

So I have had a bubble coral in my biocube 32 since I around January when I first started the tank. It was a small colony that was doing great for a while up until fairly recently. I have noticed it is closed up most of the time and has a brownish algae it seems on part of its skeleton which can...

Hello everyone, I'm new to R2R but have been keeping fish for about 2.5 years now. I just started my first saltwater tank and can't wait to share my journey with everyone along the way!

I’m a year into reefing and really want to know if it’s better to shut my whole canister filter completely off when feeding my corals. I just got this canister filter (CF500 UV MKII) for my 55 gallon reef tank, I’ve previously had two tidal 110’s on my tank and then recently transferred all the...

Hey, I found recent AF product - Anti Phosphate - https://aquaforest.eu/freshwater/products/af-anti-phosphate/ It's relatively light color, so it does not seem to be a ferric hydroxide related as most of reef dedicated products are. I wonder - what could be the ingredient and why isn't it...
