question

I’m not sure if this exists somewhere in the forum or how other people have learned this but I’m having a harder time picking it up. How do people know what a coral will look like when more grown out? Being new to the hobby I find a lot of coral that look really good, and that my tank can meet...

These little white coils are growing all over my base rocks and my back glass, any idea what they are? I’ve tried picking them off but they won’t budge.

Hello everyone i was looking into buying two wavemakers for my red sea reefer g2+ 200 and i was wondering if i should buy 2 jecod-dlw 10's or 2 jecod-dlw 20's. I was wondering if the 20 was too powerful for my 50 gallon tank? Greets

Conducting a survey!! Based on your experience what is your sps and lps coral success rate on the first 1 year of a tank preferably to more sensitive ones ( torches, acros etc) (dead rock, starting from scratch). Also if you would like to comment what after how many months you find you tank...

Could you house a Klein's butterfly in a macroalgae tank? I am aware that they aren't coral safe, but I cannot find any info on them with Macros.

I know this is a pretty odd question but I've been looking into the Ruby Scats lately and found very little beyond the basics. I know they get pretty big, do better in groups, and do tend to eat quite a bit of greens, but I was wondering if you could do a few in a macro tank? I've noticed that...

Long story short. When I started up my tank, I added too much ammonia because I was misreading my API test kits. I have since switched to Red Sea. Ammonia was sky high, I did about a 1/3 water change. Went away for a week. Came back, ammonia was even higher, Red Sea test came back blue, and...

So I just started up my new tank. As a source of bacteria, I used Ocean Direct Live Sand and Dr. Tim's One and Only for Reef tanks. For ammonia, I used Dr. Tim's Ammonium Chloride. Tank is filled with saltwater at 1.025 specific gravity. Original water is RODI. I added the bacteria and ammonium...

My clownfish recently started laying and this is their second time laying in my tank and they have laid before but not in my tank and there are a lot of eggs but only 20 hatched each time and there is complete darkness water quality is perfect but still only get a few

I just got 2 new corals and the lady at the lfs didn’t know what they were, can I get some help ID them please?

Here’s my numbers at the moment. With salifert: Alk- 8.6 Phos- .02 Mag- 1200 With Fluval master kit: PH- 8.0 Nitrite- 0.1 Nitrate- 3 I started my tank the end of last November and it’s been going good so far. Tho I have noticed in the past couple months my hammer and Duncan don’t look the...

I bought a Eheim Classic 250 from Amazon and it arrived with a broken piece shown in picture. I’ve never used a canister filter, but after taking it apart and looking it over I don’t think the broken piece will affect the functionality, but someone with more knowledge might be able to tell me...

I’ve had my clown fish for over a month now they are a breeding pair according to the previous owner the female is significantly larger than the male and they’ve been eating just fine they are the biggest fish in the tank and are left alone the water parameters are almost at zero and today I...

I need some help from the builders and structural engineers on here. I stumbled across a ridiculous deal on my dream 300 gallon deep dimensions tank (6ft L x 3ft W x 27” T). I was initially gonna put a 150 gallon tank in this spot (hence the plumbing). I am concerned if my floor can support it...

I'm not sure what's going on with my RFA and it has me concerned. He was vibrant green with a bright orange foot when I brought it home about a month and a half ago. It grew extremely quickly and eventually decided to detach from the corner it was bunkered down in and I woke up to seeing it...

Hello all, I’m new to the clownfish breeding scene and this is my first attempt at raising the fry. This group is on day 18 post hatch and have been moved to a 20g grow out tank since they are no longer on rotifers. Should I be worried that they are all schooling in the corner of the tank close...

I'm assuming that this is a bad sign. I've had a margarita snail for about a month, and I noticed that in the past few days it appears the coralline growth and patterning of its shell is flaking away to reveal a pearlescent white shell. I've only used pre-made Saltwater and distilled water...

I’ve had a Duncan for a half a year is so now, and after a friend over feeding the tank a few things showed up. There appears to be something new growing on it, but it doesn’t look like a new Duncan head. Additionally, I think there is some sort of black bubble algae, should I just leave that...

So after a year and a half I finally decided to try some sps corals. I picked up Forest Fire Digitata, Green Birdsnest, and a Grafted Monticap. They have been in the tank for about 10 days and was just wondering if they look healthy or not. At the moment I am still slowly raising alk to 8.5 and...

Does anyone know if its possible to cut a fleece roll in half? I'm thinking about 3dprinting and designing a reefmat for my waterbox cube 10. But all the fleece roll I can find here are a minimum of 8cm.. which should fit but barrelly. I want to cut let's say a red sea 250 in half but want to...

I have a 20g with a talbot damsel who I think is maturing and turning out to be an butt (yes I know who woulda thunk). It’s starting to kind of target my bar goby when it’s swimming near his rocks. I was wondering if there’s a fish I could add to disperse the aggression perhaps like a royal...

Got them in a pack, so i’m not sure what kind of corals they are. Thanks.

Hey guys so I currently have what I'm 99% sure is a male Harlequin Shrimp as his tails underside is all white. I absolutely love this guy. They are such fascinating creatures and I really want to get him a mate. I have a steady supply of food from my LFS and I have a large sump with live rock...

Can anyone with a red sea 525 XL g2+ (the newest ones that don't come with ATO reservoir) tell me if your tank has and aluminum lip on the front that supports the front panel? Just got delivery of a new tank and stand (to replace a g1 with an issue) and the support rep had said 525 and up now...

I recently cycled my tank and I entered the ugly stage so I got some clean up crew. My LFS recommended some emerald crabs along with a handful of other things. After I took them home and put them in the tank, I did some research because I thought that I’ve heard emerald crabs aren’t reef safe. I...
