question

Hello! I got my first Favia coral today. I’ve only had it for a few hours, but it doesn’t look great. It looks like some of the green has just turned into white gunk. I don’t believe it was like this when I got it, or it happened though-out the 5 hours I’ve had it. Is this bad, and anything I...

I started my reef tank back in April and it has been nothing short of a nightmare from the get go. I added a pair of clowns to the tank a few days after the startup bacteria to help with the cycling process. I elected not to QT the fish since there was nothing else in there to contaminate at the...

Hey everyone! Has anyone experimented with using a Ziss Brine Shrimp Hatchery to culture Copepods or phytoplankton? I feel like it would be super convenient the way it’s made!

Wondering what everyones thoughts are on the Tunze 9012 skimmer. I have a 135 gallon tank that has an AIO box in it with no sump and I'm looking for options for a skimmer that has to fit inside of a 6"x6" chamber. Is it a good skimmer? Are there better options for me?

What are the best hermit crab species that actively eat algae and help with things like GHA and diatoms? They also need to be small and reef safe. My snails don't do much.

I have a 16 gallon biocube with some snails that don't eat a lot of algae, zoanthids and a blastomussa coral, and a citron goby. My question is, I have a lot of algae growth on my sand bed and it looks like I am getting some hair algae on my rocks. I just got the corals yesterday. If I were to...

I am getting some dry shelf rock next Thursday and I also have a citrinis clown goby and some corals, When I add the rock, will it stress my goby or corals out too much?

I am currently acclimating some zoanthids and a blastomussa coral, I have the lights off in the tank right now. Once I get them in the tank, can I turn on the white lights or should a set it to blue lights? Or can they just go without light for another 2 hours?

I just got a citrinis clown goby today. I dont have any corals yet, but I am going to get some very soon. Is there any types of LPS or soft corals they prefer to perch on, or will they perch on all kinds of coral.

How many corals could fit in a 16 gallon biocube?

I like sun corals and chili corals specifically. I know you have to feed these, but other than that how hard are they to care for? And do they need an established tank? Could they go in a mixed reef tank? How much should I feed them? I also know that chili corals need to be put upside down.

Hello Everyone! Well, to start off, I should have listened to everyone on going bigger.... Not because it's easier but because I would want to upgrade! We just moved into a new house and I got a free 75 gallon tank (excuse the stand ... I will not be using that one. I will be building one!) and...

I was thinking about upgrading the lights on my 40b to something strong enough to grow sps and I think 3 AI primes would be probably the best way to do that for the best price. Do you guys know of anything better for around $750 dollars?

So I've had my 10 gallon for about a month now and my pair of clowns look okay so I want to add corals to encourage them to hopefully explore more of the tank since they still like the right side of the tank a lot more. I've heard mixed opinions on torches and hammer which I'm interested in but...

Hello Everyone! I recently moved into a new house and my spouse insisted I upgrade to a bigger tank as this was the time to do it! I was initially going to go with a 75 gallon, but we have a wall in the living room that is 6' and she told me to just go with the 6' 125 gallon tank so we don't...

Can you use an old quarantine tank that had some copper in it as a frag tank? How would you clean the copper out of it?

I'm into reefs not plants lol, is this light good for feeding phytoplankton?

Hi, I have a spare tank in my closet. I use it for observation. If I have an outbreak I move said animal to a hospital Acrylic box. In my observation tank, would it be beneficial to add sand? I already have live rock in there and Rubble in My hob filter. Question two, this observation tank is...

I couldn't find a better thread to post this in, but after fighting off a dino outbreak I had zero algae in the tank. At least noticeable algae. Although there are copepods. I've noticed the last two or three days my large Mexican Turbo snail hasn't been moving at all. Now I know he's still...
