coral advice

Hello, I’m quite new to reefing. I’ve transferred from freshwater I had quite the freshwater collection and breeding set ups… stingrays, rare peacocks and heaps more. Made the transition to reef tank as It all got too much and thought I would downsize into a single display tank and thought...

My hammers receding and turning white. I have a 30gal with bunch of zoas, gsp, pulsing xenia and a kenya tree that are all doing well. At the moment I have pyjama cardinal, porcelain crab, about a dozen blue legend hermit crabs and a banded coral shrimp. I have an intank protein skimmer and a...

Got a frag of Pom pom Xenia shipped 4 days ago and it is completely shriveled. Is this a lost cause? Can it recover? What can I do? I am new to the hobby and need some help. Thanks :)

So I got this frogspawn (I think it is a frogspawn) about 7 months ago. When I first got it, it looked healthy, then I'm pretty sure I bleached it with my light and it turned almost white and began to recede. Fast foward and I've moved houses and got my tank set up again. I was scared to use my...

Relatively new to corals and saltwater! I have a bubble tip anemone in my tank currently that was gifted to me. I was reading about them and say a post that said white BTA is bleached/dead. I’ll attach two photos of mine, just looking for opinions on wether or not it’s bleached as I saw...

Aquacultured coral is coral that’s grown in controlled, aquarium-style environments instead of being taken from the ocean. These systems use stable lighting, flow, and water conditions, so the corals grow up already used to the type of environment we keep in our home tanks. Because of that...

Lighting Upgrade & Trachyphyllia Reaction – Looking for Advice Hi everyone—looking for a bit of guidance. I recently upgraded my lighting from two AI Prime 16HDs to a G6 XR30 Radion because I wanted more power and the ability to keep SPS corals. I’m currently running the AB+ profile at 50%with...

Hi Guys, First time poster on any forum so here we go. Decided to convert my freshwater planted tank to Saltwater tank and so far i am loving it. Plan is to get mainly soft coral and maybe LPS tank. Tank setup on 12/11/25. Was cycling it without light so its clean. Used 2 different cycled media...

9 days ago I brought home what the shop called a kingspawn, a super fancy frogspawn with massive polyp size. It’s just a single head but this is what it looked like the day after I brought it home: The day after that I decided to feed it a small chunk of prawn just like I give to my nems, and...

Hi everyone. This is my very first post. I have had my tank running since March 2025. Right now I have one royal gramma (neo), two clown fish (Mai Tai and MooDeng), and a number of invertebrates (5 astreas snails, 5 cirith snails, 2 bumblebee snails, 1 nassarius snail, 1 margarita snail, 1 candy...

So I really need some help here with this stuff, I have insane algae growth going on in this aquarium and it’s been this way for like 2 months and keeps getting worse. Every single day I have to clean my glass and the next morning it’s completely covered again. I have 2 circulation pumps and a...

Hi all, I have been trying to keep sps and lps corals in my tank for some time, I have noticed that my phosphate levels are registering on my Hannah UL range Phosphate tester around 0.9 and my nitrates tested with the Hannah test kit are around 75ppm. I have tried keeping all kinds of easy to...

Hey guys, I’m about to do a little bit of a deep clean, water change, and revamp for my aquarium and I was wondering what the best placement for my corals are in terms of flow. Everyone seems to be doing all right, but I’d love to know the placement that would help everybody thrive and live...

Hi all sorry for the long post, I have a Cade 1500 S2 that I purchased second-hand from fakebook around a year ago to upgrade from a Waterbox 90.1. For the first 9 or so months I have had no issues with the tank, and transferred the majority of my live coral and corals across to the larger...

I hope this is the right location to post this Can anyone help with identification of some LPS torch corals - the pictures have been taken under strong blue LED lighting and the camera used is decent and gives colours super close to visually seen colours. These corals have been imported from...

Last night my frogspawn went from plump and happy to almost like a deflated balloon. All other corals in my tank are doing great, even the other frogspawn. I dont have a good before picture, but it was looking similar to the orange frogspawn picture ive provided. Params Alk- 10.5 Mag-1300...

I have a 220-gallon aquarium and have managed to get past the initial challenges and learning curve. Everything is mostly automated now. I'm looking for larger corals, but have hit a bit of a dead end in this area. Everything I find seems to be just a drop in the bucket. I would like to find...

Every time i try to spot feed the corals that benefit from consuming meaty foods, or my nems, these two go on a spree ripping food from every tentacle in the tank that has ahold of some. Is there anything I can do or a product to use to protect the corals while they eat? My poor lobo and...

Hi Reef2Reef team, Can't tell you how excited I am to have found this community. I've had this fluval 13.5 running now for 4 months. I'm going to be honest ChatGPT has gotten me this far throughout the hobby. I was wondering if you guys could take a look at my current fluval set up and give me...

noticed this lobo coralhas been having some issues notice some white buildup on the side look like worms. Took the coral out and decided to dip it today in a revive and iodine dip. Then I noticed these white worms looking things were coming out like crazy. Was wondering if anyone had any more...

Our frogspawn was thriving, living its best life (first photo - last Sunday July 20), until last Tuesday it started to decline FAST (second photo - July 27). The only new factors to the tank are that we added a few turbo snails, ninja star snails, dwarf cerith, hermit crabs, zig zag...

I have a 135 and 125 gallon reef tanks. Been in the hobby for years but still learning new things. Some of my corals colors seem not as bright as they could be. Have lots of coral. Have no nitrate and very little to no phosphate. Feed twice a day for fish. Wondering if I am low on trace...

Hey guys! I woke up this morning to a white sponge growing under our torch coral and I was wondering if it was harmful and should be removed :)I've attached a photo. Thankyou in advance!

As I re-enter the hobby, I am currently trying to plan out what kind of things I would put in my tank. When I look at corals on certain sites like LiveAquaria, they have a brief spreadsheet about the needs of each coral, such as their lighting and flow requirements, and their supplement...
