We just got back from 10 days away to find this weird, thick white substance in our sump (pics below). It's pure white, thick and is mostly on the display drain tube, and on the bottom of the refugium. There is some in the crevices of the live rock that in the refugium too. It blows off in...

Please read & select from options 1-5. Note: We keep multiple tanks and this concerns our freshwater 35g, solitary black moor. Fish was diagnosed with columnaris and has been fighting infection since October 2022. Neoplex in tank - last dose was 6/20. Neoplex in food - last dose was 6/22 as we...

Hi hopefully someone can identify this for me. I’ve never seen anything like this before. I tried to manually remove it but it’s surprisingly VERY hard to scrape off even with a toothbrush. It’s a 6month old system 125 gal with a VERY LIGHT bio load(two clowns, a gramma, softies and hammers)...

Just came back from a 2 week work trip, got some SPS that have been in my tank for 6 months that suddenly have burnt tips and some that have partially STN. Immediately ran tests but nothing standing out to me that would cause this. Trident has maintained alk, cal and mag pretty steady the...

Hi All, Thanks in advance for your time. I've scoured the internet to find a match with the symptoms i see on my hippo tang but unfortunately, with my inexperience, could not 100% ID the infection. I've tried making pictures with him free swimming but this was near impossible so I had to scoop...

Setting up my first 15 gallon tank this weekend I plan on putting 2 mocha storm clowns, a file fish, and 2 cardinals and a dart fish would this be too much for a 15 gallon?

I recently got a euphylia coral about 2 days ago and it’s not doing great, I’m not sure if it’s from the acclimation process but it’s starting to really concern me and willing to do anything to help aid it. I’m just not sure what to do I’m turning off he pumps and setting my ai light to...

Short Version: Male Clownfish ~5 years old - Spots on body appear to be missing color almost like injuries. Not scratching, eating well, has been nesting (digging big 8-10 inch divot in the sandbed). Sailfin ~5 years old - Left fin seems damaged might be due to fighting (4 zebrasoma tangs in...

Hi there, I need some advice please. I have a TMC reef habitat 60, i am waiting for a new sock holder so I can have a sock on the overflow pipe and the middle pipe. I’ve never unscrewed the middle pipe before. I’ve today went to try unscrew it and swap the current sock and holder to the...

Hey everyone, I went to my LFS yesterday and saw they had a tiny yellow goby, I knew it wasn’t a yellow clown goby because his body was slightly wider and eyes were smaller, I thought it was similar to my black barred circus goby, so I asked to see him eat and he didn’t seem very interested but...

So I was in my head tonight and was wondering if I should redo my aqua scape. My cycle should be over by the 22nd give or take. If that’s the case and my nitrates are to high I’ll probably do a 50% water change and possibly redo my aqua scape. I would most likely reuse the rock that’s in the...

He always was swimming around like crazy all day he would always take his evening laps around the tank everyday without fail, and now he doesn't even move when I feed the tank. he just has been laying down on the sand bed not even on the glass or rocks like he usually does he is just sitting on...

Need help not only identifying what kind of algae this is but also ways to help prevent and get rid of it. This tank is the Evo 13.5 with stock everything. I have added the FluvalSea Mini Protein Skimmer. Sand is Caribsea Fiji Pink. All of the levels in the tank look normal and the salt level is...

Looking for some help/advice with my mixed reef tank. Over the last month and a half I have been struggling with diatoms and cyano outbreaks, and the one I’m currently in right now is not getting better. This tank is exactly 1 year old and this is the first issue it’s having. Over the last year...

I have been running the $67 Hygger 4-channel dosing pump intermittently for the past year and am not impressed with its reliability. Recently I have had two major issues with this pump. One is that one of the heads does not allow the rollers to move at all. I suspect that the peristaltic tubing...

Hello everyone, So today I took my L2 apart for a deep clean and now for the life of me I cannot get the pump face and the motor to seal. Is there a trick out there I should know? I have had to place this on my tank and remove it a fair 6-7 times. My back can't handle much more lol.

Hi all, Yesterday was a disaster. When getting home from my LFS I drip acclimated two new juvenile engineering gobies. Did a lot of research on them and figured they would be a great addition. When adding the first one it instantly swam into the pistol shrimp/YWG den and got shot up and...

Hi, about 6 months ago i noticed my snails have not been as active. Nassarius would lay on the top of the sand and not move for days but wont die. As if they are sleeping. Turbos would sit at one corner and not move too. I got a feeling it was salinity and not mag since i dont dose mag so it...
