Hello, I recently got an XR15 pro gen6 and I’m working on a template. Right now, I’m using the phx14+ spectrum, but I’m having a bit of trouble deciding between two options. Should I have a peak intensity photoperiod of 2 hours or should I have a sinusoidal period with a peak intensity that...

I have a Prostar 150 it has 150gal of total water volume. 120g display and 30g sump. I have 3 filter socks and a protein skimmer. The tank has 4 fish total 2x orange storm clowns 1x foxface 1x 6 line wrasse 3x emerald crabs I have zero coral but would like to have a LPS dominate tank and maybe...

I recently set up a 65g with a 20g sump, but my clownfish pair is young and small so they’re not really producing any significant amount of ammonia. Someone I work with at my LFS suggested adding a few green chromis so I got three, and being that they aren’t really hardy fish anymore due to...

Hey friends! On October 23 I got what I assume to be a favia from Petco. It was labeled as an Australian coral, I tried to Google image search it. I did a coral dip from tropic marin before adding it into my tank. The first night, he put out some longish feeder tentacles (not sweepers). The...

I recently added a Midas Blenny to my 35g aquarium, with a pair of clown fish. The last Blenny that I had was super peaceful and shy, but this one has been periodically nipping at the clownfish fins and one clownfish has some damage to his back fins now. Anything I can do to help with the...

Hey guys ive been having issues with brown algae but at this point I don’t have idea what I’m dealing with. Please can you help me to identify?

Totally devastated by my latest build. Whatever it is that’s in the water or on my corals is making me lose both SPS and LPS. A little about my system: 2 year old system 100 g total volume, 3x reefled 90 2x coral plus, 2x 460 nm strips with peak par at 320 for 6 hours Skimmer with air from...

I got a pair of clownfish yesterday evening and fed them when they got home. They did not eat, probably because they weren't hungry or just aren't used to the tank. They had been hanging around the sandbed but one of them had been exploring a little bit and going around the tank a little bit...

Hello fellow Reefers! I made a post a few days ago asking for help validating some hitchhiker ID's I made. It didn't garner too much attention, but for the most part I got the answers I was looking for, with one exception (sort of). At first I thought there was some Aptasia in my Acan colony...

First tank and fish. The one clown is doing great but my other guy seems to be struggling. Added 4 days ago. Still gets up and moves around to eat. Added the air stone last night to help his breathing and been adding garlic guard to food to help boost immune system. What do you think is going...

Hello! I noticed this white blobby stuff in my rock cave about 6 months ago, but couldn't find much info on it so I cleaned it out to be safe. It appears its back now though, and after doing some more research it sounds like it could just be sponged/filter feeders? Posting here to get...

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...
