question

Every night when my lights are off, my corals look god awful at night. Melted, small, closed, just terrible, but then during the day everything looks fabulous. Is there any science or reasoning behind this? Does this happen to anyone else?

Can 2 or 3 Display tanks plumbed to the same sump technically making them an all in one system. I guess a big concern for anyone doing this is flooding in a power outage but I suppose then you do your research on what kind of sump you need or are going to make. so when the water drains it...

This is probably a silly question but I’m going to ask anyway. I have a tank that I’ve had up for a few weeks of fresh water fish and a snail. I kept going back and forth if I wanted to do salt or fresh started with fresh now I’m gonna go to salt since that’s what I really want. My question is...

Relatively newer reefer enthusiast here :) I was searching for a replacement Neptune Conductivity Probe recently and I actually found one! Apparently, it's mfg date is 2016, however, it's new with still capped solution attached (according to the supplier, Dynamictank.com). The probe is...

Bought this torch couple days ago and noticed that it’s arms had branching arms or multiple heads along with other deformities. It’s healthy and looks the same as when I bought it, was just wondering if it was normal.

Does anyone know what this is? I found this worm just sitting out on the open on a frag tile in the frag tank. Their is now sand and zero live rock. It could have been introduced on a frag plug but I dip everything before it enters this tank. I’m just confused on how I’m just now seeing this...

Hello everyone! just thought I’d start with water parameters…. They are all good. I have noticed these little lumps on my hammer coral and over the last week they have grown bigger and began to grow what look like small tentacles. Are these new heads growing?!

So I’ve had my Duncan for quite some time now and can say that it is by far my favourite coral I own. It’s grown 4 new heads since the time I originally purchased the single polyp frag and looks absolutely fantastic! With this I can’t help but wonder why the base/skeleton hasn’t grown at all...

I just put them in the same tank after putting them in small tank adjacent to each other they did not seem to be aggressive so I put them isn’t the same tank. I’ve had the blue one for a couple months now and 4 day ago I bought him a mate. I read the wiki how page about breeding beta fish and...

Hey folks! I recently upgraded my lighting on my standard 29 gallon from a Orbit Marine LED to and AI Prime. The light is sitting about 10" above the tank, and I'm getting a good spread of light all around the tank, except on the right hand side because of my two massive 15 lb rocks sitting...

Hey guys, so a little backstory: I’m a newer reefer but I’ve been a freshwater keeper a few years, and I work at my LFS. I have a 13.5 gallon fluval evo that’s been setup since mid January this year (so about 3 1/2 months). Rn I do weekly water changes and I don’t have a skimmer or fuge but I...

My friend just gave this to me. How come my holy grail is so skinny? Unlike my other torches it is the skinniest? Lol please help? I dipped it and all my parameter is ammonia: 0 Nitrite: 0 Nitrate: 0-5 PPm

I picked up a Waterbox Peninsula Mini 25 and saw they had some of their 2418 stands on clearance and went ahead and picked one up as well. The stand was made for their aquariums meant to be ran with a sump so they have a U shape cut out in the back for the overflow and return piping. So my...

Just noticed this growth on my hammer coral a couple of days ago it also retracts slightly when I shine light on it. Anyone experience something similar?

Hello! Yesterday I went to my lfs with the intentions of grabbing an anenome and 3 peppermint (hoping they’re true) to deal with my very mild aptasia issue I’ve had for the past year in my 120. Knowing myself, I walked out with 6 peppermint, a urchin, and a horseshoe crab. i purchased the...

Okay we have put the tank on the stand, Very Heavy, had a buddy help. Plumbing is dry fit currently. Would like feedback if everything looks good or if I need to change anything (means ordering more parts, so hope not) It's my first time running a sump so.... My main drain has the gate...

How many fish can I get in my 60 gallon tank? I have already have a yellow tang, blue damsel, royal gramma, 3 cromis, 2 clownfish, a clown goby , fire fish, chalk bass, and a diamond goby (I have a protein skimmer btw) I was hoping to add a longnose hawk fish and a six line wrasse

Two weeks into cycling my tank, it’s never been uglier lol. Brown algae everywhere with hair algae sprinkled in. But my ammonia is below 0.02ppm and these are my current parameters tested with api salt/fresh 5 in 1 test strips. Question is, does it look like so good so far? I’m used to...

What kind of fish is this? Looks kind of like a puffer with blue lines and dots but also kind of has horns like those you would see on a small cowfish.

Is it a Myth or Fact that corals grow faster when glued to your rock work? Please tell what you think.

Hello, I have been reading some negative reviews on the current trickle down carbon pad and bio ball system that I am running. I know this isn't an ideal sump setup, but it's the only one I can fit underneath my corner tank. I'm just looking to get the absolute most out of this space. So I was...

Hello, I'm in the process of reviving my old fowlr tank and trying to convert it to a reef tank. I see the general consensus is to now ignore the old "inch per gallon" rule when it comes to stocking the tank, so what is a realistic stock list of forgiving and hardy fish/corals/inverts for my...

Hello, a few days ago I posted a thread asking how to revive my neglected aquarium. You guys all had such good advice and with some additional tips from my local LFS I am now heading the right direction again with the tank. Just to quickly recap I left my 54 gallon corner in my basement...
