question

What is your favorite or most interesting fact about keeping a reef or about reefs in general?

What current places collect rock and keep it fully submerged during shipping? Not just wet, but in a box of water. It's rare and expensive but it keeps all the life alive.

I heard two completely different perspectives from fellow reefers this weekend and wanted to see what the broader community thinks. Do you clean your sump? If so, what’s your reasoning and how often do you do it? If you don’t clean your sump, have you noticed any impact on your system, or do...

Ok so I run an Ai prime 16HD for 11hrs total including the 2hr ramp up and down. I'm planning on having only soft corals aside from a small bit of Blastomussa wellsi. I was wondering if my lighting was ok because currently my Dendronephthya is open 100% of the lighting cycle but my GSP only...

Hey everyone, First post here and it’s a somewhat big one. I have a tank that’s a little shy of 20 gallons (rounded just for ease of conversation) and it’s getting to the point where I’m adding my last fish. (tank attached bellow). I currently have 2 clowns 1 scooter dragonet and a shrimp, goby...

What are these worm like i see on the rock. They don't look like alptesha anemone

It seems the general consensus regarding Flame Scallops is that they do poorly in captivity, and last only a few weeks to a few months if you're lucky. Just a few weeks ago, I started auto dosing 110ml daily of a live phtyo blend to my 60gal mixed reef and am tempted to give a Flame Scallop a...

Hey everyone, Lately I've been wondering why reef tanks are still kind of niche compared to freshwater setups. I keep hearing the same things from outsiders, that it's too much work or everything dies super easily or it's crazy expensive. But honestly with all the gear we have now like good...

I recently got a smatfarm 140w g6 for my 40 gal breeder, I’m looking for specific settings/height to use for a sps tank with fish. This is my first reef tank so I’m gonna do mostly easy to keep corals to start

Hello! I'm relatively new to this, but I recently wanted to try and culture my own phytoplankton to use as food for other creatures I want to take care of, as well as run some projects on them. I work at an aquarium, so I went and did a plankton drag to gather some samples and brought them...

So I’m visiting family in Berthoud Colorado went to a local Lfs which have a very nice selection of what may be Mardi Gras bounce mushrooms for only 40 dollars I live in socal and am leaving back home Sunday my flight will be 11:15 I am thinking about getting the mushrooms tommorow on Saturday...

So, I've got a question, about phyto and pods. I know they are beneficial for the tank, but also food for fish and corals. And I'm wondering, how does it work, should I culture them in my DT (no sump) or should I have separate containers for them, and dose them as needed? If you could link any...

Does anyone have experience keeping fish in a tank that is too small for them on a temporary basis? I’m setting up a new tank and have thought about keeping fish in a 40 gallon breeder while working on the build. The only fish that would need a bigger tank would be my two spot tang. He...

I picked up this hammer coral but I dont know what its called. The guy at the lfs said it might be a toxic hammer but to me it looks more like an Australian splatter but the teal base on the stems throw me off. I like to know the names of all my corals so I would like to know what this one is...

Hey does anyone know of any active Papua New Guinea fish exporters? The last time I saw anything come into the US from Papua New Guinea was a couple years ago. If their are no active ones, then does anyone know what happened?

Can someone tell me if this trachy looks happy or stressed? It seems to constantly be slightly puffier than when I bought it months ago and this picture here shows it at its max today. I read online that it could be searching for food or it could be stressed, and not to attach it to rock work...

I'm really new to the hobby and just set up my tank to begin its fishless cycling period. I've looked through some other threads, but want to ask some questions more specific to my tank and lights :]. First, some background info. I did some tests today, and my parameters are as follows pH 7.7...

Does Anyone Know why Innovative Marine has gone away with their 25 lagoon Aps stand , 10 - 15 gallon and tank stands ? and few other small changes ? I thought I read somewhere someone bought them out but now cant find anything , Really like their products hope they didnt get bought out by a...

Hi all, just bought 2 days ago a Clavularia Viridis from my LFS, The guy there said to just put her on the rock I want her to colognise, since she got a “Not conventional form” (not flat at all) I was wonder If she will adapt by herself to the rock, The guy at the LFS told me to place it so that...

Hello everyone, I have a question, that I hope I can find some assistance with on here. I included some photos below, or my female clownfish. I will say this is now the 3rd time she’s exhibited this behavior and it’s quite strange to me, but she basically will stop eating, abandon the male...

Hello fellow Hobbyists & Reefers! I was doing general research on what I wanted to add to my upcoming tank, and I want to keep a LOT of butterflyfish together. Specifically, I want Three Chaetodon collare also known as the Pakistan Butterflyfish as well as with two other different species of...

So I have a 13.5 gal reef tank. My calcium levels are usually 400 ppm (after water changes, which happen weekly) and I dose all for reef 2ml in the morning and 1ml in the afternoon. This keeps my alk stable at 8.45 but my calcium keeps dropping. This tank is loaded with lps and softies with a...

My first puffer used to bite the rocks and scoop up sand, but can I also use cuttlefish bone or other stuff? I just bought a 1 inch baby porcupine puffer so he's not big enough to eat live crabs.

Hey everyone, Are there any of you genius people out there that have created your own protein skimmer? I am in a pickle because finding a skimmer that would fit in my sump. I only have a clearance of around 18.5 inches vertically. Although I only need one for a 75 gallon, finding appropriately...

Hello all! My first question here, probably of many! I have done freshwater tanks for about 4-5 years, recently got into saltwater a year ago I have a established 75 gallon in my room, it has been cycled for about 5 almost 6 months, and I also have a established quarantine tank that has been up...
