question

I’ve been wanting to setup my 125g for a while and I just finished moving so it’s finally time to start planning everything. My issue is that I only plan on staying in this house for 3 years before I move into a more permanent home, I hate moving tanks and moving my 125g the first time made me...

I often find myself looking online for inspiration for my reef tank that I’m gonna be setting up. I see a lot of tanks that are super mature and grown in and the corals are just absolutely packed into the tank. I’m talking like 15 corals on a rock. How is this possible? Are coral stings not as...

Hi, all! I'm new here as I just made an account, but I've been creeping for quite some time since starting to keep marine fish 8 years ago. Thank you all for everything I've learned! This may not be exactly the correct forum to post this, but I figured if anyone knows if this is breeding...

Someone on another site was telling me I shouldn't feed my new corals because it stresses them out. How true is this? I fed them 1-2 tiny pieces of brine shrimp just to see what would happen, figuring there was no harm in it. Can I ask what the reasoning behind this is, or better yet, why...

I am looking at making a 2" hole in my wall to run a piece of PVC through the wall and into my garage. In the garage i want to keep stuff like my ATO, automation tools, and some other items for my tank. The temp in there fluxuates a fair bit but it never freezes or gets much above 80-90F. It...

Hello! My LFS had a black blunt spine brittle star on sale and I made an impulse purchase because I love the way they look. I know most brittle stars are reef safe but I’ve read that some may eat fish. Does anyone have experience with this type of brittle star?

Hi, I’ve had this Vlamingi Tang for a couple months now and he has been a family favorite. He is super friendly, eats aggressively, gets along with tank mates (Invited my Vampire Tang to school with him and other fish after a day), and overall a super great fish. He has never shown any negative...

Can I spot feed Red Sea AB plus to my bta?

Hello, I am having an issue that I cannot find the fix to. My return line is connected by tubing to a bulkhead, then loc line connectors in the tank in an arc to prevent siphoning, which works. but, When I turn my tank off, water continues to drain into the sump very slowly , what could this be...

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...
