Hello! I have been freshwater keeping for a few years, and I have just started cycling my first saltwater aquarium. I know I have a lot to still learn, and it's going to take some time, but I'm ok with that and excited to start reefing! Equipment so far: 40 gallon breeder 40 pounds of live...

Bought my mushroom a few weeks to about a month ago, noticed some weird activity from it acting normal, to not expanding/shriveling, then acting normal. I noticed a purple looking growth going down the side of the rock it’s on for about a week now. I look into my tank tonight to find it...

Hello, I started in this hobby over a year and a half ago and this site along with many others have helped me navigate the reef tank world for all this time with major success and the occasional incident. Finally, I made an account days ago and was going to post a fun thread introducing myself...

I just finally finished setting up my 65g and turned the pump on for the first time. I noticed the flow seemed really loud so I looked in the corner-flow section where the noise was coming from. It turns out that there’s a hole on the underside of the elbow that my loc line is connected to, and...

Sorry if this seems like a stupid question but I'm genuinely concerned, so in the past I lost all my fish to either ick or velvet (it was one or the other) so I completely left my tank fishless for a very long time (coral only), but due to a lightning issue all of my coral died (light became too...

This snail does nothing but eat my snails . I got it from a home shop as part of a clean up crew .... need help identifying this snail and if I should get rid of it ....thank you Hard to get really good photos in the position it's in hope they work

Help!! I’m setting up a marineland 65g tank with a built in overflow section, and with the way the drilled hole is positioned on the bottom of the tank, the pipe is tilted to get to the space provided for the return. Is this what it’s supposed to look like?

Initially thought it might have been a mantis, but nothing has died from it, nor been disturbed by it seemingly. So I’m curious if anyone has had this happen. Below is a video and a listing of the little equipment I have running. Innovative Marine 100 Gallon INT Aquarium with full...

Hey guys! A friend sold me what he believed was a mini maxi, but after now seeing it face to face i really think it’s a haddoni. It’s small, maybe 10cm across? But the tentacle length and shape really doesn’t strike me as mini maxi:). I’ll attach the photos. Foot is a grey colour, no spots or...

Hello, I was finally able to record my dominate clownfish shaking against the sand bed. I’ve had her for two months and the only other fish is an other clown I had for 3 weeks. I’m pretty sure she started this behavior 5 days ago because I was able to notice the sand bed looking different. She...

In a little bit of a unique situation here. I got zoanthids/plays growing on my crocea clam shell. It’s getting to a point where they’re starting to cover the mantle. My current remedy is irritating the zoas so they close for a period of time, but I can only do that so often. I can’t use kalk...

Hello, my dominate clown has been rubbing its lower body against the sand bed at night and I’ve never seen this before. I’ve had it for two months and the only other fish is another clown I’ve had for 3 weeks. Should I be worried?

Hello! I have a hard coral that I got from a LFS about 8-10 months ago. I honestly do not remember exactly what this coral is, and would appreciate some help in IDing it. It is also starting to bleach from the inside out it looks like. I have had 0 changes to my tank besides add a couple...

Hi all - I have this purple-reddish algae covering all my rocks and filter equipment. I have read about cyanobacteria and coralline algae, but this algae does not seem to match either description. It spreads fast on rocks and hard surfaces but seems to stay away from my crushed coral substrate...

Morning, all! I'm helping an elderly relative replace her lighting on her 150gal softie reef. 2 out of the three T247s are going bad, so she's springing on the 66" Blade. The T247s were running 100% Blue from 9am-7pm, whites 20% 10am-5pm. What kind of settings should I be going for to not...

I cut the small piece of the protruding plastic (in the back chamber) on my Flex 15, in order to fit my protein skimmer. small pieces of plastic got into the water column, I tried my best to get them out of the water with a fine net but could this cause damage to any fish or corals in the long run?

Hi, I’ve posted about my tank before on other groups but it’s kinda going backwards so I’m asking for help once again. I set up my Fluval evo in march. I have 2 damsels, 5 pieces of life rock, and a mangrove. I have the stock light. It’s been looking brown for about 2 months. I thought it was...

Hello I was curious to if anyone knows if this is ich? Thank you so much

Hi fellow reefers, I’ve been battling low pH issues in my Marine X 110.4 for a long time now, and I’m really concerned. My pH just won’t go above 7.7 (sometimes it even drops to 7.6). I’ve done everything I can think of to improve the situation: I’ve moved to a bigger apartment, opened doors...

I have a 30 gallon setup that will eventually go into a 150 gallon next year. I have a basic ni crew light, a heater, a fluval canister filter (no sump) a hang on back oase protein skimmer, a fluval uv light that connects too my filter, a auto top of system, auto feeder, 2 wave makers, carib sea...

Hello, I have been dealing w a weird algae/ Dino’s? I was wondering if anyone could help me ID

Hello all, I’m having some troubles with the corals in my 65g tank. It’s my first reef, so keep in mind I’m fairly new to this. None of my corals seem to be growing, and I’m really lost as to why. I have lost two corals (Kenya tree and Duncan) for unknown reasons. Other than those, I have some...

As the title says, I have a new tank. My livestock consists of two clowns, two nassarius snails, and two cerith snails. I feed the clowns pellets and mysis shrimp (not at the same time. The mysis are a treat). The nassarius snails do a great job on the uneaten mysis, but they really don't go...
