The title like the title says I left my dosing pump on all night. I plugged it into the wrong timer and instead of turning on for one minute every two hours it ran continuously for about five hours. I estimate that a dose between 2 to 300 mL of all for Reef… Into my Evo 13.5 gallon tank Now my...

Hi all just wanted some help on know what this coral is. Can’t tell if it’s some kind of singulars or a devils hand. Got it super cheap at the LFS and didn’t ask anything of it. TIA!

hello everyone! I'm really new to reef2reef but I'm anxious for some advice from the lovely folks here. To make a long story short, I have no idea what animal(s?) I can keep in my tank! it's a 65L tank with a heater, thermometer, sponge filter + airline going into it, and a pretty standard white...

Hi everyone , I just got a bubble tip anemone for my tank and noticed this weird thing moving next to it while I am acclimating. Does anybody know what it is ?the arms also move

I have a newly set-up aquarium, and I bought this little guy because i thought it would sift through sand. It is never in the sane. At first it, it was on thr glass as show in the pictures, then it was on the live rock, and now it is on the glass again as in the current photos. My worry is: is...

I’ve had this PBT for a week now, proactively treated with prazi first (for 5 days) did a 50% WC and started copper power. Raised copper to 2.5 over the coarse of 48hrs. Found it lying on the bottom of the tank this morning barely moving. Did a freshwater dip and it sadly passed. Can anyone tell...

Hello been having this angle for about 3 weeks, he had no signs of infection besides the ick. I dipped him in hydroplex for 10 minutes and tossed him in my tank. I’ve been dosing rally pro to help mitigate the ick and grounded ginger which has helped. However a new infection has arrived being on...

Hello! I got a rock flower nem 3 days ago and it’s been doing great, this morning it was out of sight but I was told that they move a lot sometimes when first put into a tank. Well I wanted to make sure it was okay and now it looks like it’s been ate in half!! I was told that it’d be safe in my...

Hi everyone, Basically I left testing for 2 weeks and had a mag/cal and alk drop so I’ve just fixed that then i was looking and in the last 2 days one of my clowns disappeared fully with no trace, (the tanks only 4 months old) so I moved all the rocks looking for him, now my phosphate has gone...

I've made a few posts about my system. Simple corals like Green Star are not growing, my torches, hammers are slowing shrinking and dying. Fish are growing, look healthy eating well and have no issues. What on earth is wrong - what possible next steps could I take? - I'm about to give up My...

Hi guys, I have 2 clowns right now in my tank and one of them (the male) has suddenly started breathing very radidly and is not eating. He ate great yesterday but did not eat today. He ate maybe 1 pellet. I tried spot feeding with both mysis shrimp and pellets but he isn’t interested in it and...

Hello all, first post here on R2R! I love this site because it almost always answers any questions I have. So I thought I’d give it a try with questions directing towards my setup. First off I have a 20g long Innovative Marine Lagoon. It’s been up for about a month. I recently upgraded from a...

Hello, this is my first time on this forum and I need help. In the last 2 months I've been setting up my 15 gallon saltwater fish tank. A few weeks back I introduced my clown fish and the majority of my CUC when all the chemistry levels in the tank were correct. A week after I introduced a...

Hey, my desjardini sailfin tangs bloated and lethargic, he also didn’t eat seaweed when we fed today, could this be dropsy? or does anyone have any thoughts? The parameters are all good and every other fish is doing fine, he has been staying swimming in one corner of the tank. At this same time...

hey all, i’ve been reading for hours on here and believe i’ll get the same answers but i figured it’s worth a shot. all parameters are within normal range. i have the possum wrasse, a tail spot blenny, and now a bicolor dottyback in my 10 gal. the dottyback was added just yesterday. i am...

I have been dealing with cyano for months. It was horrible and covered all my tank and killed a lot of my corals…. Now the past few weeks my tank is starting to clear up and it’s almost all clear… The past two weeks though my tank can’t seem to get rid of this corner of cyano and some green...

So if you know me at all you probably know that I’ve been preparing my (roughly) 10g dwarf seahorse tank for many months now. Two days ago they finally came in the mail, I got six. Three male and three female. One of them wasn’t doing well on arrival and ended up passing that day after getting...

I have a RedSea 750XXL (200 gallon display with sump) and think I have created a high bioload with lots of fish and corals. I am losing lots of my corals. Chemistry: I am experiencing high nitrates and phosphates. I have tried to lower feeding but can't get them under control. Hence, I started...

I got this Duncan a week ago It looked healthy and happy in the shop When I got it home it was fully closed as I expected It hasn’t opened up since and this morning it’s looking bad Is it bailing or is it ok and just sulking

I’m currently running an eshopps S-120 on my 130g system with a 90g display tank with what I would call a moderate to heavy bioload. A LFS near me has a barely used reef octopus 110SSS space saving skimmer for sale. The rating online says 60gal heavy bioload, 90 medium, 130 light. I would go...

Hey all. I just got a 75 gallon and notice a strange line on the top left of it. It runs a little bit and is wavy, and kind of thins out to nothing. I can feel it with my fingers it feels like a smooth bump. I just don’t know if it’s a crack or silicone. I am halfway setting it up and noticed...

So, about a month ago, I got a YWG, and he was good for the night. Then I woke up the next morning, saw him, he went out of his little cave he was in for the night, swam behing the rockscape, and never saw him since. Now, about 2 days ago, I got another YWG, and later through the first night. He...

Hi everyone. This is my anemone, and she’s clearly suffering quite a lot. She’s been in the tank for over two months. Recently I had some sudden parameter drops due to coral additions, specifically KH and magnesium. I didn’t catch it in time — I’m still a beginner — and both of my anemones were...

Can I please get some help with the id of this torch. I received the frag today and the seller is adamant that it’s a ny Knicks however it looks exactly the same as my indo gold (at the top) of the comparison photo. I appreciate it’s still settling in but doesn’t look like a ny kicks to me. He...
