help

I can't find any other algae that looks remotely similar. Has anyone ever seen algae like this? It grows in long vine like strands along the rock and has spread across all my rocks. Easy enough to remove with tweezers but can never remove all of it. Thanks.

Hi, recently my tank has been running with lower nitrates as before and one major thing i realised was slower coral growth and they aren’t as puffy. I only keep lps and softies and they both have slowed down in growth ever since my nitrates dropped to 5. I used to run my tank with high nitrates...

I have these white filaments all over the tank. Also have a vermetid outbreak that I am treating with bumblebee snails and manual removal. Alk is 10.5, salinity 1.025, phosphates, nitrates and pH are I in normal limits. Any help is greatly appreciated!

Looking for some help.. So I had what I thought was a pair of biota mandarin goby’s. Well turns out as they matured I have two males… I know the simple answer is to just separate them and take one out but my problem is we a 93 gallon and have built an extensive BRS hsna aquascape. So other...

I recently began noticing an issue with my Duncan coral. It has been a little more closed up than normal but not much. on the side skeleton area of the duncan there is a bit of tissue recession. There is a open patch on the upper section that is surrounded by a yellow 'rim'. Where the skeleton...

I started to notice some of this clear white stuff growing on my rocks can anyone tell me what it is?

Pretty certain this is green Cyano. Tank was severely neglected. Went through a divorce moved tank twice in less than 6 months. Then couldn’t keep up with maintenance. I know I did it to myself but I’m trying to get back on track. Lost all my coral except GSP and some mushrooms, fish made it...

Hi all, I'm looking for some advice really. I have been experiencing some issues with my corals for the past 2-3 weeks now. Initially I had found a faulty power head giving me a fair amount of stray voltage into the water (nasty zap!) However since rectifying this I expected to see improvement...

Hey all. I received a BTA thru overnight shipping on 04/21 and promptly acclimated it and put it in my 90 gallon tank. He went under a rock pretty quickly and was there all day yesterday. I moved the rock to check on it and possibly feed it shrimp a few hours ago and this is what I saw. Is it...

Newbie reefer here. Recently, I've been battling a brown-ish growth in my sand bed. I suspect it's cyano due to the presence of small tendrils, but its brown so could it be diatoms? Its a 75G, currently stocked with 2 ocellaris clowns, 1 royal gramma, 1 firefish, 1 starry blenny, and 1 pajama...

Hi there, I have an aggressive Pygmy Hawkfish. I’m having problems introducing new fish to the reef tank. I was curious what you guys suggest? Should I return him to LFS? Or are there specific fish that I should get that might be compatible with his temperament?

Hey everyone! I got a green BTA delivered yesterday and after putting it in, it was moving around quite a bit and it's foot was firmly attached to the rock work but it was looking quite deflated which I assume was normal after shipping overnight. Upon searching the entire tank for it all night...

Hey guys, I recently bought a goni frag and it looked really good in the store. It was already growing small baby heads down the sides so i knew it wasn’t a recent frag. Anyway I brought it back and acclimated for 45 mins and put it in the tank. It didnt open up that day which i guess is normal...

Hey guys this is my first big tank 65”L 30”W & 17” tall (pretty much 150g according to BRS calculators). Will be a budget build because I can’t convince myself why to buy the higher end stuff. Doesn’t make sense to me. Please let me know if they’re are better suggestions/options! :) return...

I have a aqua knight over my 20 gal and I would like to know what settings I should have it on for coral.

I recently bought a 60 gallon with sump and stand on facebook marketplace for $200, I think the total volume is ~80 gallons. I'm a 16 year old working on this tank on a smaller budget. The equipment I need is a return pump and eventually a skimmer. What skimmer will work for the tank that won't...

is this the right place for this? not my main display but my families 150g mixed reef has T O N S of limpets and for a while i didn’t think anything of it which turned out to be a mistake…… acan colony that’s normally super healthy and full had been closed for two weeks or so before i stepped...

Hi everyone, recently I had encountered a problem with my tank. I was getting stray voltage in my water from one of my pumps. I have replaced the defective part but since this has happened none of my corals have really opened. Before this happened I was seeing really nice growth and extension...

Okay i have a 20g tank divided in the centre for my clownfish breeding project. New fish seem to be dying for no reason but there definitely is a reason which i dont know yet. Swimming happily at 6pm then dead at 9pm. But then theres others in there which are fine. Same tank same water. The tank...

My tank is going on two months old, I have always had a hard time identifying diatoms from Dino’s. What do y’all think? I have been having trouble getting my NO3 & PO4 up and my setup has ceramic bio rings and uses standard medium size tetra filter cartridges with activated carbon in them...

Looking for input on what may be going on that my gem tang just stopped eating. I got him about 10 days ago he has been in 20 gallon QT doing TTM. Qt was medicated with copper power (2.6ppm). He was eating frozen like a pig, fat and happy. 2 days ago he stopped eating all together. I have not...
