question

what type of green algae is this?

So Ive been wanting to turn my 29 gallon tank into an anemone tank for a while but I don't have the money to afford an API light which is the only light I’ve been able to find that’s recommended. Are there any good amazon lights or multiple smaller lights that wont break my bank. I’d be willing...

Hey all, it's been a few years since I kept a saltwater tank - my expertise is definitely in freshwater and turtles. In the past I had 2 thriving reef tanks with fish & LPS but once my ex and I broke up I kept the freshwater and he took the salt tanks (he was definitely the salt expert!) So...

For anyone that uses the X aqua overflow kit - what return pump do y'all use? I have the sicce syncra 3.0, and I have to cover up the overflow in order to keep the water level in the tank, or it will just drain to the bottom of the overflow pipe.

I got a tank custom made by a guy who has been making aquariums for decades and is highly recommended by local reefers. People have allegedly had tanks running from him for decades with no leaks. However I’m not sure if I should be concerned with the structural integrity of the tank? I was quite...

got it as a gift for doing a favor and want to know if it’s a good deal or not.

Hi, I have recently started up my reef tank again, had a total tank shut down one of my fish got velvet and it all went down hill from there. I got everything back up and running though, recently started with some softies doing okay and my LPS (hammer and Frogspawn) are doing amazing. I was...

Hello I've recently just setup a 150gallon tank that I'm looking to make primarily an SPS Reef. I do already have a few fish for it that have been in my 40g macro tank for the last 2 months. Those fish are a pair of SixLine Wrasse and two Aiptasia eating Filefish. The one fish that I really...

Hey again Reef2Reef! Today I noticed something I’ve never seen before on my candycane coral. It appeared to have a grey crack on one of the heads. It looks weird in comparison to the rest of the coral. I don’t know if it’s starting to bleach or if it’s just a sign of growing like stretch marks...

Hi! This is my first post on the forum so please let me know if I’m doing something incorrectly. I bought this Exquisite Wrasse 4 weeks ago and he displayed no abnormal behavior until around a week and a half ago. He started to swim around at the top of the tank and now he rarely goes down into...

Hello! I am new to the hobby and am in the process of planning out my first reef tank. The tank that I have selected is 48" long and 24" wide and 20" tall with two flexible return pump discharge points in the middle back of the tank. I am very interested in the Vortech MP40 powerheads but I...

I set up my new tank yesterday and like an idiot I accidentally left the pump power connector in the water. There is nothing in the tank as i just started cycling it yesterday.I used my multi meter to look for stray voltage and it didnt look like there was any in the water or anything super off...

Hello, everyone! I'm posting on behalf of my dad, so please bear with me. He's got a 60-gallon tank with an Apex system, and all parameters have been checked and double-checked. All other fish, anemones, and corals seem fine, but something is going on with his orangetip bristletooth. We...

Hi all. I have the Oceanic Creator 2 The issues is that the probes have a range when to add saltwater or DI water. As you can see on my apex there is a daily and sometimes by entire 1 point during 2 days. There is no way to make it more stable. Do you think this is hurting my system? Are those...

What are these little pink blobs that are appearing? They move in the flow if it hits them just right. They are hard to describe - kind of like a pink blob that was smushed into a pancake. I do apologize about the picture quality - I need to get a better phone. Thank you!

My tank is a 16 gallon Biocube. Right now I am not satisfied with my aquascape. I have three pieces of dry rock I want to put in my tank. My question is can I add all three pieces in at once or should I do it more slowly? I am also wondering how I should prepare it to go into my tank. Should I...

Hello all, I have a 10g fairly new tank. Worry not everything is cycled of course but I started noticing orange patches here and there on my sand. All levels are within normal ranges so I have no idea what this might be, but then again I still consider myself a beginner and I don’t know much...

Hey everyone, so quick question I was having a breakout of Dino’s and I’m sure cyano over the pat 6 months. I ended up breaking down the tank as I’m setting up a 60 cube. I took all the rock out that had all the Dino slime and hosed it off and it’s pretty much outside. Can I reuse the rock...

Hi everyone, I’ve had this school of about 20 blue/green chromis I got around a year ago. They are currently in a 225G and being fed with frozen brime, cyclops, scraps of seaweed left the tangs, and small stuff in the water column throughout the day. So far there’s has been no aggression. I...

Hi there. I recently set up a tank dedicated to a Harlequin pair. I received both through a package and after acclimating them, I noticed that the female was displaying behavior indicating she was preparing to molt (slow and limited movement, hiding in rockwork, etc.). She molted 2 days after...

Hi all so today I was of course in my tank with no gloves which was dumb of me but I was just sticking a frag to its new home. Anyway I scraped my index finger by the cuticle and immediately took my hand out and washed it with water and soap and put neosporin on it. fast forward this morning, I...

Back when I started almost a year ago, I didn't realize how big of a deal drip acclimation and having a QT process was. Due to that, two fish and a shrimp were lost. I was just curious what others did or did not do at the start of their reefing hobby that now seems impossible to forget due to...

Are flatworms really that bad? They look ugly but don’t seem to be effecting anything. I have those yellow rasses and those blue damsels. Those guys don’t eat the flatworms. When I feed I’ll dip rocks in RO and take a couple dead flatworms and drop them in with the food to get them accustomed to...

I know I need a light, sand, and rock. Which light would work? Would this be a nano or aoi build for a build thread? What else do I need? I want to do a budget build. I plan on having Zoa’s and Ricordia One clown. would a yellow watchman gobie and pistol shrimp be too much? thanks

Hey guys ! I really would love your ideas, input, Suggestions on coral businesses. I plan on starting a veteran owned and operated coral business in the next year or so. I want it to be like no other business out there. All coral will be aquacultured and priced to compete with wild caught...
